thermal runaway caused fire and explosIon of lithium Ion Battery
Journal of Power Sources, 2012Co-Authors: Qingsong Wang, Ping Ping, Xuejuan Zhao, Chunhua ChenAbstract:Lithium Ion Battery and its safety are taken more consideratIon with fossil energy consuming and the reductIon requirement of CO2 emissIon. The safety problem of lithium Ion Battery is mainly contributed by thermal runaway caused fire and explosIon. This paper reviews the lithium Ion Battery hazards, thermal runaway theory, basic reactIons, thermal models, simulatIons and experimental works firstly. The general theory is proposed and detailed reactIons are summarized, which include solid electrolyte interface decompositIon, negative active material and electrolyte reactIon, positive active material and electrolyte reactIon, electrolyte decompositIon, negative active material and binder reactIon, and so on. The thermal models or electrochemical-thermal models include one, two and three dimensIonal models, which can be simulated by finite element method and finite volume method. And then the related preventIon techniques are simply summarized and discussed on the inherent safety methods and safety device methods. Some perspectives and outlooks on safety enhancement for lithium Ion Battery are proposed for the future development. Language: en

pilotaxitic na1 1v3o7 9 nanoribbons graphene as high performance sodium Ion Battery and aqueous zinc Ion Battery cathode
Energy Storage Materials, 2018Co-Authors: Yangsheng Cai, Guozhao Fang, Jiang Zhou, Fei Liu, Zhigao Luo, Anqiang Pan, Shuquan LiangAbstract:Abstract For the development of high-performance sodium and aqueous zinc Ion batteries, the exploitatIon of suitable cathode materials is urgently needed. In this work, pilotaxitic Na1.1V3O7.9 nanoribbons/graphene (Na1.1V3O7.9@rGO) have been prepared. As cathode for sodium Ion Battery, the Na1.1V3O7.9@rGO delivers high capacities at different rates. Stable capacity of 84.8 mA h g−1 is obtained at 1 A g−1 after 500 cycles, corresponding to a low capacity fading rate of 0.015% per cycle. The ex-situ XRD and TEM results demonstrate good structural stability of Na1.1V3O7.9@rGO. Most importantly, the layered structure of Na1.1V3O7.9@rGO is firstly employed as cathode for aqueous zinc Ion Battery. This composite can deliver a high capacity of ~ 220 mA h g−1 at 300 mA g−1, as well as good cyclic stability, which suggests the sodium vanadates may be a good cathode candidate for aqueous zinc Ion Battery.

highly durable na2v6o16 1 63h2o nanowire cathode for aqueous zinc Ion Battery
Nano Letters, 2018Co-Authors: Ting Zhu, Mengyu Yan, Xuanpeng Wang, Xiujuan Wei, Wen Luo, Wei Yang, Wencui Zhang, Liang Zhou, Zhiqiang Zhou, Liqiang MaiAbstract:Rechargeable aqueous zinc-Ion batteries are highly desirable for grid-scale applicatIons due to their low cost and high safety; however, the poor cycling stability hinders their widespread applicatIon. Herein, a highly durable zinc-Ion Battery system with a Na2V6O16·1.63H2O nanowire cathode and an aqueous Zn(CF3SO3)2 electrolyte has been developed. The Na2V6O16·1.63H2O nanowires deliver a high specific capacity of 352 mAh g–1 at 50 mA g–1 and exhibit a capacity retentIon of 90% over 6000 cycles at 5000 mA g–1, which represents the best cycling performance compared with all previous reports. In contrast, the NaV3O8 nanowires maintain only 17% of the initial capacity after 4000 cycles at 5000 mA g–1. A single-nanowire-based zinc-Ion Battery is assembled, which reveals the intrinsic Zn2+ storage mechanism at nanoscale. The remarkable electrochemical performance especially the long-term cycling stability makes Na2V6O16·1.63H2O a promising cathode for a low-cost and safe aqueous zinc-Ion Battery.
