摘要: 同锂离子电池相比,全固态锂电池不仅安全性好,而且在提高比能量、比功率密度以及循环性能方面也有更大的空间,从而得到广泛关注。在现有全固态锂电池中全固态薄膜锂电池(TFB)的制备工艺成熟,电池性能优异,已率先实现了商品化生产。同传统的锂离子电池不同,TFB的主要制备方法是物理成膜形成致密正极、电解质和负极薄膜,各层薄膜采用原位叠加方式形成。本文总结了近十年来TFB的研究工作,力图囊括全固态薄膜电池的完整制备过程以及各制备环节的技术进展和存在的科学技术问题。本文首先分述了固态电解质薄膜、正极薄膜、负极薄膜等三个主要构成部分的研究进展和关键问题,在此基础上,归纳了电极/电解质界面的设计、制备以及TFB制备过程及其关键问题和技术的研究进展,最后还介绍了基底、集流体、封装三个辅助部分的制备过程以及最近报道的新型特殊结构TFB。

Abstract: All-solid-state thin film lithium batteries (TFBs) have better safety as well as greater potential in the energy density, power density and cycle life than lithium ion batteries (LIBs). TFBs have the most mature preparation technology among the exiting type of all-solid-state lithium batteries, which performance were excellent and were also taking the lead to achieve the commercialization. The states of art preparation of TFBs were quite different with LIB, which is mainly depending on physical deposition. Every part of TFBs such as cathode, anode, electrolyte and collector was prepared into high density films followed with in situ stack. This review summarizes the progress and advances for the studies of TFBs in the recent decade. We tried to give an airscape from the view points of the whole preparation of TFBs, the existing problems of scientific and technical. The solid inorganic electrolyte film, cathode film and anode film regard as three main steps for TFBs preparation, which progress and key issues of were described separately. On this basis, the whole preparation of TFBs and the TFBs with special structure were discussed, following with the brief advances of substrate, current collector and encapsulation.
