    Co-Authors: Nam-soon Choi, Yang-kook Sun, Stefan A. Freunberger, Jaephil Cho, Xiulei Ji, Linda F Nazar, Khalil Amine, Gleb Yushin, Zonghai Chen, Peter G Bruce
    Abstract:

    Energy-storage technologies, including electrical double-layer capacitors and rechargeable Batteries, have attracted significant attention for applications in portable electronic devices, electric vehicles, bulk electricity storage at power stations, and "load leveling" of renewable sources, such as solar energy and wind power. Transforming Lithium Batteries and electric double-layer capacitors requires a step change in the science underpinning these devices, including the discovery of new materials, new electrochemistry, and an increased understanding of the processes on which the devices depend. The Review will consider some of the current scientific issues underpinning Lithium Batteries and electric double-layer capacitors.

  • silicate cathodes for Lithium Batteries alternatives to phosphates
    Journal of Materials Chemistry, 2011
    Co-Authors: Saiful M Islam, Robert Dominko, Christian Masquelier, Chutchamon Sirisopanaporn, Robert A Armstrong, Peter G Bruce
    Abstract:

    Polyoxyanion compounds, particularly the olivine-phosphate LiFePO4, are receiving considerable attention as alternative cathodes for rechargeable Lithium Batteries. More recently, an entirely new class of polyoxyanion cathodes based on the orthosilicates, Li2MSiO4 (where M = Mn, Fe, and Co), has been attracting growing interest. In the case of Li2FeSiO4, iron and silicon are among the most abundant and lowest cost elements, and hence offer the tantalising prospect of preparing cheap and safe cathodes from rust and sand! This Highlight presents an overview of recent developments and future challenges of silicate cathode materials focusing on their structural polymorphs, electrochemical behaviour and nanomaterials chemistry.

    Abstract:

    Abstract The future of rechargeable Lithium Batteries depends on new approaches, new materials, new understanding and particularly new solid state ionics. Newer markets demand higher energy density, higher rates or both. In this paper, some of the approaches we are investigating including, moving Lithium-ion electrochemistry to higher potentials, nanowire or mesoporous electrodes and an O 2 cathode, will be discussed.

  • Nanomaterials for rechargeable Lithium Batteries
    Angewandte Chemie-International Edition, 2008
    Co-Authors: Peter G Bruce, Bruno Scrosati, Jean-marie Tarascon
    Abstract:

    Energy storage is more important today than at any time in human history. Future generations of rechargeable Lithium Batteries are required to power portable electronic devices (cellphones, laptop computers etc.), store electricity from renewable sources, and as a vital component in new hybrid electric vehicles. To achieve the increase in energy and power density essential to meet the future challenges of energy storage, new materials chemistry, and especially new nanomaterials chemistry, is essential. We must find ways of synthesizing new nanomaterials with new properties or combinations of properties, for use as electrodes and electrolytes in Lithium Batteries. Herein we review some of the recent scientific advances in nanomaterials, and especially in nanostructured materials, for rechargeable Lithium-ion Batteries.

  • Formulation of Blended-Lithium-Salt Electrolytes for Lithium Batteries.
    Angewandte Chemie (International ed. in English), 2019
    Co-Authors: Xuehui Shangguan, Shanmu Dong, Xinhong Zhou, Guanglei Cui
    Abstract:

    Blended-salt electrolytes showing synergistic effects have been formulated by simply mixing several Lithium salts in an electrolyte. In the burgeoning field of next-generation Lithium Batteries, blended-salt electrolytes have enabled great progress to be made. In this Review, the development of such blended-salt electrolytes is examined in detail. The reasons for formulating blended-salt electrolytes for Lithium Batteries include improvement of thermal stability (safety), inhibition of aluminum-foil corrosion of the cathode current collector, enhancement of performance over a wide temperature range (or at a high or low temperature), formation of favorable interfacial layers on both electrodes, protection of the Lithium metal anode, and attainment of high ionic conductivity. Herein, we highlight key scientific issues related to the formulation of blended-salt electrolytes for Lithium Batteries.

  • Progress and prospect on failure mechanisms of solid-state Lithium Batteries
    Journal of Power Sources, 2018
    Co-Authors: Bingbing Chen, Longlong Wang, Guanglei Cui
    Abstract:

    Abstract By replacing traditional liquid organic electrolyte with solid-state electrolyte, the solid-state Lithium Batteries powerfully come back to the energy storage field due to their eminent safety and energy density. In recent years, a variety of solid-state Lithium Batteries based on excellent solid-state electrolytes are developed. However, the performance degradation of solid-state Lithium Batteries during cycling and storing is still a serious challenge for practical application. Therefore, this review summarizes the research progress of solid-state Lithium Batteries from the perspectives of failure phenomena and failure mechanisms. Additionally, the development of methodologies on studying the failure mechanisms of solid-state Lithium Batteries is also reviewed. Moreover, some perspectives on the remaining questions for understanding the failure behaviors and achieving long cycle life, high safety and high energy density solid-state Lithium Batteries are presented. This review will help researchers to recognize the status of solid-state Lithium Batteries objectively and attract much more research interest in conquering the failure issues of solid-state Lithium Batteries.

  • novel cellulose polyurethane composite gel polymer electrolyte for high performance Lithium Batteries
    Electrochimica Acta, 2016
    Co-Authors: Kailiang Liu, Shanmu Dong, Xinhong Zhou, Meng Liu, Junmei Cheng, Chengdong Wang, Qingfu Wang, Hongguang Sun, Xiao Chen, Guanglei Cui
    Abstract:

    Abstract The increasing interest in gel polymer electrolyte for the Lithium battery is attributed to its excellent plasticity, enhanced safety and significantly improved electrochemical stability. Herein, on account of the two-phase structure of thermoplastic polyurethane (TPU) consisting of soft and hard segments, the cellulose/TPU with ether bond composite gel polymer electrolyte (CGPE) was fabricated and investigated for applications in Lithium Batteries. This study demonstrated that the CGPE possessed preeminent comprehensive properties such as sufficient ionic conductivity (4.8 × 10 −4  S cm −1 ) at 80 °C, high Lithium ion transport number (t +  = 0.68) and improved electrochemical stability. Moreover, the assembled LiFePO 4 /Li battery using CGPE exhibitedoutstanding rate capacity and remarkable cycle performance at the elevated temperature of 80 °C. Notably, the discharge capacity was still 128.2 mAh g −1 after 200 cycles, 95% of the capacity retention at a charge/discharge rate of 2C. These findings suggest that CGPE is a very prospective polymer electrolyte for high-performance Lithium Batteries.

  • Recent advances in all-solid-state rechargeable Lithium Batteries
    Nano Energy, 2017
    Co-Authors: Chunwen Sun, Yudong Gong, David P Wilkinson, Jin Liu, Jiujun Zhang
    Abstract:

    The all-solid-state Lithium Batteries using solid electrolytes are considered to be the new generation of devices for energy storage. Recent advances in this kind of rechargeable Batteries have brought them much closer to a commercial reality. However, several challenges such as insufficient room temperature ionic conductivity (10−5~10−3 S cm−1) when compared to those of conventional organic liquid electrolytes (10−2 S cm−1), the difficulty in informing an effective electrode-electrolyte interface and insufficient fundamental understanding of the interfacial process after charge/discharge, hindering the reality of such devices. To accelerate the research and development, the overall picture about the current state of all solid-state Lithium Batteries was reviewed in this article with major focus on the material aspects, including inorganic ceramic and organic solid polymer electrolyte materials. In particular, the importance of the electrolytes and their associated interfaces with electrodes as well as their effects on the battery performance are emphasized by in-depth discussion and data analysis. To overcome the challenges, several possible research directions are also suggested for facilitating further improvement on the battery performance.
