摘要:

全固态锂电池由于具有安全性高、循环寿命长、能量密度高等特点,在化学电源领域具有非常好的应用前景。因全固态锂电池是一种使用固体电极材料和固体电解质材料,不含任何液体的锂电池,所以全固态锂电池的电极制备以及组装与现有液态锂电池的方法存在较大差异。本文详细综述了典型的几类全固态锂电池的电极制备与组装方法及相应的性能特征,分别针对氧化物、硫化物以及聚合物固体电解质体系,归纳分析其结构、正极制备方法、负极修饰方法以及电池组装方式,并在最后对全固态锂电池的实验室开发组装方式给出了建议,为全固态电池研究的同行们提供借鉴和参考。

Abstract:

All-solid-state lithium batteries, with good safety, long life and high energy, are an emerging option for next-generation technologies on the road to a green energy storage device. All-solid-state lithium batteries are prepared with all-solid electrode and all-solid electrolyte without liquid additives. Therefore, the electrode preparation and assembly of all solid-state lithium batteries are quite different from those of existing liquid lithium batteries. Here we summarize the typical assembly approaches of prototype all-solid-state batteries using oxide, sulfide, or polymer as solid electrolytes, providing reference for all-solid-state battery researchers.In this paper, the electrode preparation and assembly technology with the corresponding performance characteristics of several typical all-solid-state lithium batteries are reviewed in detail. The structure, cathode preparation methods, anode modification methods and battery assembly methods of oxide, sulfide and polymer solid electrolyte are summarized and analyzed respectively. Finally, some suggestions on the laboratory development and assembly methods of all solid state lithium batteries are given.

Key words: all-solid-state lithium batteries, electrodes preparation, assembly technology, solid electrolyte, lithium batteries
