摘　　要：半固态锂电池是将可脱嵌锂的活性材料颗粒和导电剂颗粒分散在电解液中形成电极材料的一种新型电化学储能技术,与传统锂离子电池相比,预计其规模化生产成本低,且避免了锂离子电池中电极材料粉化脱落的问题,因此电池循环寿命更长。目前半固态锂电池发展出了两种技术类型:半固态锂液流电池和半固态锂浆料电池,其技术原理已经通过验证,进入到基础关键技术开发阶段。本文综述了半固态锂电池的国内外研究进展,并对研发过程中的关键技术问题进行了总结和分析。The semi-solid lithium battery is a new type of electrochemical energy storage technology.It uses a uniform mixture of energy storage particles,conductive particles and electrolyte as the semi-solid electrode.Compared with the traditional lithium ion battery,this new technology has the significant advantage of low cost in the large-scale application.Besides,the cycle life of the battery can be extended by refraining the electrode material from being pulverized and detached from the current collector.At present,two kinds of semi-solid lithium battery have been developed:semi-solid lithium flow battery and semi-solid lithium slurry battery.The technical principle has been verified.In this paper,the research progress of the semi-solid lithium battery is reviewed,and the key problems during the research process are summarized and analyzed.
