摘要
采用水电解质溶液的锂离子电池(简称水系锂离子电池)虽然能量密度较低,但可解决采用有毒、易燃有机溶剂电解液锂离子电池所涉及的安全性和高成本问题,同时有望克服现有水系可充电电池(如铅酸和镍氢电池)寿命短的瓶颈,作为智能电网用的储能电池具有很好的应用前景.本文综述了近年来水系锂离子电池在新型电池体系及相关电极材料的一些研究进展,对该领域所面临的挑战做了简单的讨论,并提出一些建设性的观点及可能的解决方案.此外,还对近两年发展起来的以金属锂为负极的水系电池体系(双液体系)做简单总结.
Although the lithium-ion battery using aqueous solution as electrolyte has low energy density, it may solve both the safety and large cost problems for lithium-ion batteries that use highly toxic and flammable organic solvents, and the poor cycling life associated with commercialized aqueous rechargeable batteries including lead-acid and nickel-metal hydride batteries, showing promising application in stationary power sources for smart grid. The present work reviews the latest advances in the exploration and development of battery systems and related materials. Also the main challenges in this field are briefly discussed and some constructive views and possible solutions are provided. On the other hand, present work also reviews the recent progress of the application of Li-metal anode, and analyzes its advantage, disadvantage and challenge.
