The point of this review is mainly focusing on the safety and practicability of solid-state lithium ion battery. And this review emphatically discusses and analyzes these practical manufacturing methods and strategies by illustrating some novel and excellent reported examples instead of barely collecting and classifying these new materials over the years. Based on the current industrial technology and market requirements, we summarize four types of most practical solid-state electrolytes (polymer gel, PEO-based, garnet-type and sulfide-type electrolyte) whose potential of application, strategy of improvement and possibility of mass production are all analyzed in this review. Li ion transport mechanisms in different electrolytes, which are commonly accepted in recent years, are summarized and stated as well. Besides, the key interfacial problems of electrolytes and electrodes for solid batteries is emphatically discussed and we also sort out some useful methods for actual production. And there are some interesting and novel content in this paper, which is that the lithium metal is not considered as an anode material because we think that is not realistic and economical for industrial manufacture in recent years and the polymer gel is analyzed to be a great transition electrolyte from liquid electrolyte batteries to all-solid-state batteries.

这篇综述的重点主要放在固态锂离子电池的安全性和实用性上。这篇评论通过阐述一些新颖而出色的实例，着重讨论和分析了这些实用的制造方法和策略，而不是多年来仅收集和分类这些新材料。根据目前的工业技术和市场需求，我们总结了四种最实用的固态电解质（聚合物凝胶，PEO基，石榴石型和硫化物型电解质），它们的应用潜力，改进策略和大批量生产的可能性在此评论中对所有生产进行了分析。总结和阐述了近年来在不同电解质中锂离子的迁移机理。除了，着重讨论了用于固体电池的电解质和电极的关键界面问题，并为实际生产提出了一些有用的方法。而且本文中有一些有趣而新颖的内容，那就是锂金属不被视为负极材料，因为我们认为近年来对于工业生产而言这是不现实且不经济的，并且聚合物凝胶被认为是一种很好的材料。将电解液从液体电解质电池过渡到全固态电池。
