后锂电池时代新型电池的开发与展望

石油、天然气等化石能源的枯竭及人类生存环境的进一步恶化,迫使人们寻求和开发清洁可再生能源和高效绿色的储能装置.传统的锂离子电池等已难以满足将来电动汽车等大规模使用的电器对于大容量蓄电装置的要求.文章综述了日本产业技术综合研究所周豪慎教授课题组近年来的研究成果,介绍了组合型电解液的概念及原理,并重点讨论了锂-铜电池和锂-空气电池等基于组合型电解液的后锂离子电池的设计方法和电化学性能.文章指出,组合电解液技术将是开发高能量电化学储能装置的重要思路和有效方法.

The development and prospects of advanced batteries in the post-lithium battery era

Due the limited supply of fossil fuels and environmental degradation arising from flue gas emissions,it is imperative to discover clean and sustainable energy,and to develop effective and green energy storage devices.Conventional lithium ion batteries cannot meet the requirements of future large scale electrical applications such as electrical automobiles which need higher energy density.We present here an overview of our recent work,beginning with an introduction to the concept and principle of hybrid electrolytes,and followed by a detailed discussion of the design and electrochemical performance of hybrid electrolyte-based post-lithium batteries such as Li-Cu and Li-air batteries.The hybrid electrolyte technology is considered to be a promising method to develop electrochemical high energy storage devices.
