A theoretical method to predict novel Organic Electrode materials for Na-ion batteries
Computational Materials Science, 2017Co-Authors: Wanwan Zhang, Pengkun Sun, Shaorui SunAbstract:Abstract Currently known Organic Electrode materials for lithium-ion batteries have severe cost and resource constraints and are difficult to implement in applications for large-scale electrical energy storage. Compared to lithium-ion battery Electrode materials, sodium-ion battery Electrode materials are more abundant and more cost effective. However, methods for the prediction of Organic Electrode materials for sodium-ion batteries are not perfect at present. A fast and accurate theoretical method for finding possible candidates for Organic Electrode materials for Na-ion batteries is urgently needed. In the present work, dispersion-corrected hybrid density functional theory is applied to study five Organic Electrode materials for Na-ion batteries. The results of this study show that the D2 dispersion-corrected hybrid functional method (HSE06-D2) can precisely calculate the potential of Organic materials with a small average error of approximately 3.68%. The band gap values are approximately lower than 2.5 eV, which proves that the materials have good conductivity and are expected to be candidates for Organic Electrode materials for sodium-ion batteries.

A precise theoretical method for high- throughput screening of novel Organic Electrode materials for Li-ion batteries
Journal of Materiomics, 2017Co-Authors: Wanwan Zhang, Pengkun Sun, Shaorui SunAbstract:Abstract Organic Electrode materials have gained significant attention due to their flexibility, lightweight characteristics, abundant resources in nature, and low CO2 emission. It's urgently needed for setting up an accurate high-throughput screening theoretical scheme that could find out possible candidates of Electrode materials. Currently, the error between the theoretical potentials calculated by the PBE-D2 (DFT-D2, dispersion-corrected density functional theory) method and the experimental values is larger than 12%. Thus, it's essential to finding a more accurate method. In the present work, hybrid functionals and vdW correction methods are applied to investigate six reported Organic Electrode materials for Li-ion batteries. The results show that the hybrid functional combined with the D2 dispersion corrected method, i.e., HSE06-D2 (Heyd, Scuseria, and Ernzerhof, dispersion-corrected), is able to predict the potential of the Organic material precisely with an average error of approximately 5%. This method occupies much hardware resources and being very time consuming, but it could be applied as the final ultrafine step in the high-throughput screening program.

Study of Lithium Migration Pathways in the Organic Electrode Materials of Li-Battery by Dispersion-Corrected Density Functional Theory
The Journal of Physical Chemistry C, 2015Co-Authors: Yanhui Chen, Shaorui Sun, Xiayan Wang, Qinghua ShiAbstract:Organic materials have been considered a promising alternative as Electrodes for rechargeable lithium-ion batteries. However, there are some obvious shortcomings, especially poor dynamics performance. Approaches to understand the reason for the poor dynamic performance are the main point of the present work. In this paper, an Organic Electrode material,C12H4N4, is selected as a sample, and studied by dispersion-corrected density functional theory (DFT-D2). The calculation results show that the band gaps of delithiated and lithiated states are about 0.9 and 1.0 eV, respectively, which is consistent with the conventional conjugated Organic materials implying the good electronic conductivity. The Li-ion migration pathway forms a complicated three-dimensional (3D) network. The migration energy barrier is higher than 0.53 eV, which is obviously higher than that of the inOrganic Electrode material, demonstrating the poor ionic conductivity. In Organic materials, although the steric hindrance is lowered due to t...

High Throughput Screening of Organic Electrode Materials for Lithium Battery by Theoretical Method
The Journal of Physical Chemistry C, 2015Co-Authors: Shaorui Sun, Yanhui ChenAbstract:Screening the appropriate Organic Electrode material of a lithium battery from the Organic structure database by the theoretical method efficiently is crucial for the further experimental study. Unfortunately, the density functional theory is not appropriate due to that it fails to calculate the van der Waals interaction between the Organic molecules. In this work, dispersion-corrected density functional theory (DFT-D2) was applied to study nine experimentally reported Organic Electrode materials, and the theoretical method successfully predicted their potentials, which suggests that it is a feasible method to search and investigate the Organic Electrode material. The method is further applied to investigate 31 Organic crystallines selected from the CCDC (Cambridge Crystallographic Data Centre) database. The theoretical results show that the potentials range from 0.01 eV to 2.76 V, while the capacities distribute from 150 to 623 mAh·g–1, and most of the band gaps are smaller than 2.5 eV, which indicates t...

First-Principles Study of an Ethoxycarbonyl-Based Organic Electrode Material of Lithium Battery
The Journal of Physical Chemistry C, 2014Co-Authors: Yanhui Chen, Shaorui SunAbstract:Organic molecules are potential candidates for Electrode materials of rechargeable lithium batteries because of their beneficial properties such as cost-effective, environmentally friendly, and sustainable. Until now, the efficient theoretical method to study the Organic Electrode materials remains elusive. In this paper, an Organic Electrode material of a lithium battery, Li2C18O8H12·4H2O, is investigated by the dispersion-corrected density functional theory method. Two outlined points are presented: (1) the method is a powerful tool to predict the geometry structure and the discharge potential of the Organic Electrode material; and (2) the periodic crystal structure does more to determine the property of the Organic Electrode material than the single molecular structure. The intermediate structure corresponding to the first discharge plateau is explored, in which the reversible inserted Li ion occupying layers and the unoccupying layers are arranged alternatively. The special structure makes the interme...

reversible lithium ion uptake in poly methylmethacrylate thin film via lithiation delithiation at in situ formed intramolecular cyclopentanedione
Advanced Energy Materials, 2016Co-Authors: Yan Wang, Haoshen Zhou, Honghe Zheng, Li Zhang, Liya Zhang, Fei ZhangAbstract:Herein, it is proposed that poly(methylmethacrylate) (PMMA), a widely-used thermoplastic in our daily life, can be used as an abundant, stable, and high-performance anode material for rechargeable lithium-ion batteries through a novel concept of lithium storage mechanism. The specially-designed PMMA thin-film Electrode exhibits a high reversible capacity of 343 mA h g−1 at C/25 and maintains a capacity retention of 82.6% of that obtained at C/25 when cycled at 1 C rate. Meanwhile, this pristine PMMA Electrode without binder and conductive agents shows a high reversible capacity of 196.8 mA h g−1 after 150 cycles at 0.2 C with a capacity retention of 73.5%. Additionally, PMMA-based binder is found to enhance both the reversible capacity and rate capability of the graphite Electrodes. Hence, this new type of Organic Electrode material may have a great opportunity to be utilized as the active material or rechargeable binder in flexible or transparent thin-film batteries and all-solid batteries. The present work also provides a new way of seeking more proper Organic Electrode materials which don't contain conjugated structures and atoms with lone pair electrons required in traditional Organic Electrode materials.

Polyanthraquinone as a Reliable Organic Electrode for Stable and Fast Lithium Storage
Angewandte Chemie (International ed. in English), 2015Co-Authors: Zhiping Song, Haoshen Zhou, Hui Zhan, Yumin Qian, Minoru Otani, Mikhail L. Gordin, Duihai Tang, Donghai WangAbstract:In spite of recent progress, there is still a lack of reliable Organic Electrodes for Li storage with high comprehensive performance, especially in terms of long-term cycling stability. Herein, we report an ideal polymer Electrode based on anthraquinone, namely, polyanthraquinone (PAQ), or specifically, poly(1,4-anthraquinone) (P14AQ) and poly(1,5-anthraquinone) (P15AQ). As a lithium-storage cathode, P14AQ showed exceptional performance, including reversible capacity almost equal to the theoretical value (260 mA h g(-1); >257 mA h g(-1) for AQ), a very small voltage gap between the charge and discharge curves (2.18-2.14=0.04 V), stable cycling performance (99.4% capacity retention after 1000 cycles), and fast-discharge/charge ability (release of 69% of the low-rate capacity or 64% of the energy in just 2 min). Exploration of the structure-performance relationship between P14AQ and related materials also provided us with deeper understanding for the design of Organic Electrodes.

Energy and Environmental Science, 2014Co-Authors: Zhiping Song, Haoshen Zhou, Yumin Qian, Xizheng Liu, Tao Zhang, Yanbei Zhu, Minoru OtaniAbstract:Organic Electrode materials are promising alternatives to transition-metal based intercalation compounds for the next generation of high-performance and sustainable batteries. Herein, a novel quinone-based Organic, lithium salt of poly(2,5-dihydroxy-p-benzoquinonyl sulfide) (Li2PDHBQS), was successfully synthesized through a simple one-step polycondensation reaction, and applied as a cathode for Li–Organic batteries. As an oligomeric lithium salt with average polymerization degree of 7, Li2PDHBQS combines the advantages of the O⋯Li⋯O coordination bond and increased molecular weight, thus solves absolutely the dissolution problem of active material in non-aqueous electrolytes, which has seriously hindered development of Organic Electrode materials. Benefiting from the high theoretical capacity, intrinsic insolubility, fast reaction kinetics of the quinone group, accelerated Li-ion transport and uniform blending with conductive carbon, as well as the stable amorphous structure, Li2PDHBQS shows superior comprehensive electrochemical performance including high reversible capacity (268 mA h g−1), high cycling stability (1500 cycles, 90%), high rate capability (5000 mA g−1, 83%) and high Coulombic efficiency (99.9–100.1%). Investigation of the structure–property relationship of Li2PDHBQS and its analogues also gives new insights into developing novel quinone-based Organic Electrode materials, for building better Li–Organic or Na–Organic batteries beyond traditional Li-ion batteries.

In this paper we provide an overview of Organic Electrode materials, including their fundamental knowledge, development history and perspective applications. Based on different Organics including n-type, p-type and bipolar, we firstly analyzed their working principles, reaction mechanisms, electrochemical performances, advantages and challenges. To understand the development history and trends in Organic Electrode materials, we elaborate in detail various Organics with different structures, including conducting polymers, organodisulfides, thioethers, nitroxyl radical polymers and conjugated carbonyl compounds. The high electrochemical performance, in addition with the unique features of Organics such as flexibility, processability and structure diversity, provide them great perspective in various energy storage devices, including rechargeable Li/Na batteries, supercapacitors, thin film batteries, aqueous rechargeable batteries, redox flow batteries and even all-Organic batteries.

Prospects of Organic Electrode materials for practical lithium batteries
Nature Reviews Chemistry, 2020Co-Authors: J. ChenAbstract:Organic materials have attracted much attention for their utility as lithium-battery Electrodes because their tunable structures can be sustainably prepared from abundant precursors in an environmentally friendly manner. Most research into Organic Electrodes has focused on the material level instead of evaluating performance in practical batteries. This Review addresses this by first providing an overview of the history and redox of Organic Electrode materials and then evaluating the prospects and remaining challenges of Organic Electrode materials for practical lithium batteries. Our evaluations are made according to energy density, power density, cycle life, gravimetric density, electronic conductivity and other relevant parameters, such as energy efficiency, cost and resource availability. We posit that research in this field must focus more on the intrinsic electronic conductivity and density of Organic Electrode materials, after which a comprehensive optimization of full batteries should be performed under practically relevant conditions. We hope to stimulate high-quality applied research that might see the future commercialization of Organic Electrode materials. Organic materials can serve as sustainable Electrodes in lithium batteries. This Review describes the desirable characteristics of Organic Electrodes and the corresponding batteries and how we should evaluate them in terms of performance, cost and sustainability.

molecular electrostatic potential a new tool to predict the lithiation process of Organic battery materials
Journal of Physical Chemistry Letters, 2018Co-Authors: Luojia Liu, Licheng Miao, Zhenfeng Shang, J. ChenAbstract:This work is pioneering to introduce molecular electrostatic potential (MESP) to investigate the interaction between lithium ions and Organic Electrode molecules. The electrostatic potential on the van der Waals surface of the Electrode molecule is calculated, and then the coordinates and relative values of the local minima of MESP can be correlated to the Li binding sites and sequence on an Organic small molecule, respectively. This suggests a gradual lithiation process. Similar calculations are extended to polymers and even Organic crystals. The operation process of MESP for these systems is explained in detail. Through providing accurate and visualizable lithium binding sites, MESP can give precise prediction of the lithiated structures and reaction mechanism of Organic Electrode materials. It will become a new theoretical tool for determining the feasibility of Organic Electrode materials for alkali metal ion batteries.

Design Strategies toward Enhancing the Performance of Organic Electrode Materials in Metal-Ion Batteries
Chem, 2018Co-Authors: Qiu Zhang, Zhiqiang Niu, J. ChenAbstract:Summary Organic Electrode materials have shown great potential for metal-ion batteries because of their high theoretical capacity, flexible structure designability, and environmental friendliness. However, their electrochemical performance still needs to be further enhanced, which mainly depends on the molecular structures, Electrode fabrication, electrolyte, and separators. In this review, we present the working principles and fundamental properties of different types of Organic Electrode materials, including conductive polymers, organosulfur compounds, Organic radicals, carbonyl compounds, and other emerging materials. We then focus on the strategies toward enhancing the electrochemical performance (output voltage, capacity, cycling stability, and rate performance) of Organic Electrode materials in various metal-ion batteries. The key challenges of Organic Electrode materials for metal-ion batteries mainly contain the high solubility in electrolyte, low intrinsic electronic conductivity, large volume change, and low tap density. This review provides insights into the development of Organic Electrode materials with high performance for next-generation rechargeable metal-ion batteries.

An Insoluble Benzoquinone-Based Organic Cathode for Use in Rechargeable Lithium-Ion Batteries.
Angewandte Chemie (International ed. in English), 2017Co-Authors: Zhiqiang Luo, Luojia Liu, Qing Zhao, J. ChenAbstract:Organic Electrode materials of rechargeable batteries have attracted a great interest because of their containing of renewable C, H and O elements, but meanwhile face the challenge of high solubility in Organic electrolyte. We here report an Organic Electrode of tetra-(phthalimido)-benzoquinone (TPB) through introducing the rigid groups into benzoquinone molecular skeleton which showed insoluble character in aprotic electrolyte, revealing a high capacity retention of 91.4% (204 mA h g-1) over 100 cycles at 0.2 C. The extended conjugated structure also contributes to enhancing high-rate perfomance (155 mA h g-1 at 10 C ). Moreover, density functional theory calculations illustrate that favorable synergistic reaction between multiple carbonyls and lithium-ions can also enhance initial Li-ion intercalation potential. Our results demonstrate that grafting rigid groups on molecular skeleton provide new approaches for next-generation Organic Electrode materials of lithium-ion batteries.

advanced Organic Electrode materials for rechargeable sodium ion batteries
Advanced Energy Materials, 2017Co-Authors: Qing Zhao, Yong Lu, J. ChenAbstract:Benefiting from the high abundance and low cost of sodium resource, rechargeable sodium-ion batteries (SIBs) are regarded as promising candidates for large-scale electrochemical energy storage and conversion. Due to the heavier mass and larger radius of Na+ than that of Li+, SIBs with inOrganic Electrode materials are currently plagued with low capacity and insufficient cycling life. In comparison, Organic Electrode materials display the advantages of structure designability, high capacity and low limitation of cationic radius. However, Organic Electrode materials also encounter issues such as high-solubility in electrolyte and low conductivity. Here, recently reported Organic Electrode materials, which mainly include the reactions based on either carbon-oxygen double bond or carbon-nitrogen double bond, and doping reactions, are systematically reviewed. Furthermore, the design strategies of Organic Electrodes are comprehensively summarized. The working voltage is regulated through controlling the lowest unoccupied molecular orbital energies. The theoretical capacity can be enhanced by increasing the active groups. The dissolution is inhibited with elevating the intermolecular forces with proper molecular weight. The conductivity can be improved with extending conjugated structures. Future research into Organic Electrodes should focus on the development of full SIBs with aqueous/aprotic electrolytes and long cycling stability.

Stable cycling of small molecular Organic Electrode materials enabled by high concentration electrolytes
Energy Storage Materials, 2020Co-Authors: Taotao Cai, Yan Han, Qing Lan, Feng Wang, Jun Chu, Hui Zhan, Zhiping SongAbstract:Abstract Small molecular Organic Electrode materials (SMOEMs) enjoy favorable high capacity and low cost, but suffer from poor cycling stability and low Coulombic efficiency due to the unavoidable dissolution in aprotic electrolytes. Previous studies of the dissolution inhibition strategy mainly focused on the molecular designing or Electrode engineering, but neglected the important or crucial influence of the electrolyte. Herein, a facial “high concentration electrolyte” strategy is employed to study two typical dianhydride molecules, namely 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTCDA) and 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA), achieving dramatically improved cycling stability for both. Remarkably, in 3 M LiTFSI/DOL + DME electrolyte (lithium bis(trifluoromethanesulphonyl)imide/1,3-dioxolane + 1,2-dimethoxyethane), PTCDA shows a high capacity retention of 87% (relative to the maximum capacity of 147 mAh g−1) after 1000 cycles at a current rate of 100 mA g−1, along with an exceptional average Coulombic efficiency of 99.99%, setting one of the best cycling performance records for SMOEMs. The comparative study of NTCDA and PTCDA in LiTFSI/DOL + DME electrolytes with different concentrations (1, 2, 3, and 4 M) indicates that both intrinsic crystalline structure stability of the active material and appropriate electrolyte are key origins of good cycling stability. According to ex-situ characterization results, a “dissolution–redeposition” mechanism of SMOEMs is proposed to update researchers’ obscure understanding of the dissolution behavior. We believe this work provides not only confidence on the performance potential but also insightful mechanism understanding of SMOEMs, which are important for their further development towards practical application.
