a novel solid oxide redox flow battery for Grid Energy Storage
Energy and Environmental Science, 2011Co-Authors: Xuan Zhao, John B Goodenough, Kevin HuangAbstract:In this work we report proof-of-concept of a novel redox flow battery consisting of a solid oxide electrochemical cell (SOEC) integrated with a redox-cycle unit. The charge/discharge characteristics were explicitly observed by operating between fuel cell and electrolysis modes of the SOEC along with “in-battery” generation and Storage of H2 realized by an in situ closed-loop reversible steam-metal reaction in the redox-cycle unit. With Fe/FeO as the redox materials, the new Storage battery can produce an Energy capacity of 348 Wh/kg-Fe and round-trip efficiency of 91.5% over twenty stable charge/discharge cycles. This excellent performance combined with robustness, environmental friendliness and sustainability promise the new battery to be a transformational Energy Storage device for Grid application.

Recent advances of electrode materials for low-cost sodium-ion batteries towards practical application for Grid Energy Storage
Energy Storage Materials, 2017Co-Authors: Yunming Li, Yaxiang Lu, Chenglong Zhao, Yong-sheng Hu, Maria-magdalena Titirici, Hong Li, Xuejie Huang, Liquan ChenAbstract:Abstract Energy Storage plays an important role in the development of portable electronic devices, electric vehicles and large-scale electrical Energy Storage applications for renewable Energy, such as solar and wind power. Lithium-ion batteries (LIBs) have dominated most of the first two applications due to the highest Energy density and long cycle life. Room-temperature sodium-ion batteries (SIBs) have re-attracted great attention recently, especially for large-scale electrical Energy Storage applications. This is on one hand due to the abundant and widely distributed sodium resources and on the other hand due to the predicted lower cost from using Na, as well as Al current collectors for both cathode and anode. One of the important advantages as well as challenges in SIBs is to use low-cost materials as active electrodes to compete with LIBs in terms of cost/kWh. In this review, both cathode and anode materials for SIBs are reviewed, with focus on the latest development of electrode materials from 2013. Advantages, disadvantages and future directions on the existing electrode materials will be discussed based on the literature and our experience. Although a large number of electrode materials have been reported in the literature, SIBs are still facing grand challenges, which can be overcome by continuing the research efforts to search for new electrode materials with better performance, lower cost, higher safety and more stable interface with electrolyte. Once the right electrode materials are discovered throughout a fundamental understanding of the intimate relationships between its structure and performance, we believe that SIBs with low cost and long life will have promising prospects in low-speed electric vehicles (e.g., bicycle, quadricycle, etc.) and large-scale Energy Storage in the future.

Energy Storage Materials, 2016Co-Authors: Liping Yue, Jun Ma, Jingwen Zhao, Shanmu Dong, Guanglei Cui, Jianjun Zhang, Zhihong Liu, Liquan ChenAbstract:All solid-state polymer electrolytes have been received a huge amount of attention in high-performance lithium ion batteries (LIBs) due to their unique characteristics, such as no leakage, low flammability, excellent processability, good flexibility, wide electrochemical stability window, high safety and superior thermal stability. In this review, we summarized a series of all solid-state polymer electrolytes based on modified poly (ethylene oxide), polycarbonate, polysiloxane, succinonitrile and organic-inorganic hybrid composite. The recent progress on all solid-state polymer electrolytes has been reviewed in term of their potential application in LIBs. It is expected that the high-performance solid-state polymer electrolytes can be used in portable electrochemical devices, electric vehicles and Grid Energy Storage.

an intermediate temperature garnet type solid electrolyte based molten lithium battery for Grid Energy Storage
Nature Energy, 2018Co-Authors: Jialiang Lang, Denys Zhuo, Zeya Huang, Yang Jin, Hui Wu, Changan Wang, Kai Liu, Yi CuiAbstract:Batteries are an attractive Grid Energy Storage technology, but a reliable battery system with the functionalities required for a Grid such as high power capability, high safety and low cost remains elusive. Here, we report a solid electrolyte-based molten lithium battery constructed with a molten lithium anode, a molten Sn–Pb or Bi–Pb alloy cathode and a garnet-type Li6.4La3Zr1.4Ta0.6O12 (LLZTO) solid electrolyte tube. We show that the assembled Li||LLZTO||Sn–Pb and Li||LLZTO||Bi–Pb cells can stably cycle at an intermediate temperature of 240 °C for about one month at current densities of 50 mA cm−2 and 100 mA cm−2 respectively, with almost no capacity decay and an average Coulombic efficiency of 99.98%. Furthermore, the cells demonstrate high power capability with current densities up to 300 mA cm−2 (90 mW cm−2) for Li||LLZTO||Sn–Pb and 500 mA cm−2 (175 mW cm−2) for Li||LLZTO||Bi–Pb. Our design offers prospects for Grid Energy Storage with intermediate temperature operations, high safety margin and low capital and maintenance costs.

high capacity li2s graphene oxide composite cathodes with stable cycling performance
Chemical Science, 2014Co-Authors: Zhi Wei Seh, Yi Cui, Haotian Wang, Nian Liu, Guangyuan Zheng, Hongbin YaoAbstract:With its high theoretical capacity of 1166 mA h g−1, Li2S is a promising prelithiated cathode material for applications such as vehicle electrification and Grid Energy Storage. Herein, we demonstrate facile synthesis of Li2S–graphene oxide composites for use as high-capacity and stable-cycling Li2S cathodes. The wrapping of graphene oxide onto the surface of Li2S through favorable lithium–oxygen interactions helps to minimize the dissolution of intermediate polysulfides into the electrolyte during cycling, which is a major reason for rapid capacity decay. Using the Li2S–graphene oxide composites as a cathode material, we demonstrate a high discharge capacity of 782 mA h g−1 of Li2S (∼1122 mA h g−1 of S) with stable cycling performance over 150 charge–discharge cycles.
