Abstract:

At present,commercial lithium ion batteries（LIBs） mostly use organic liquid electrolyte,which is flammable,explosive,leaky and other security risks.The use of solid electrolyte instead of organic liquid electrolyte could effectively improve the safety of batteries.The solid electrolyte for Li-ion battery can be divided into inorganic electrolyte and organic（polymer） electrolyte.Inorganic solid electrolyte has good adaptability to high temperature or other corrosive environment,which is suitable for rigid battery in extreme working environment;polymer solid electrolyte has obvious advantages in flexibility and processability,which is suitable for flexible battery and other fields,but these materials still have problems to be solved.Inorganic-organic complex is expected to integrate the advantages of the two materials,learn from each other and improve the comprehensive performance and practical value of solid electrolyte.

Key words: lithium ion batteries, inorganic solid electrolyte, polymer solid electrolyte
