Abstract: Recent research work of solid-state thin fin batteries mainly focus on the constructon of electrodelelecrolyte interaces with a low impedance and the development of solid elecrolytes with a high ionic conductivity.In this review, the structure design and ion ransport mechanism of solid-state thn fim battery were inroduced.The research progress of anode fim, cathode fim and solid elecrolye fimn were represented.In aditon,some problems of lctrodelelectrolyte interfaces and their improvement strategies were also summarized.
