Abstract

Compared with liquid organic electrolytes, lithium ion conductive solid electrolytes offer improved safety, reliability and leakage-free properties, as well as the advantageous wider electrochemical voltage ranges and the possibility for structural batteries. For this reason, all-solid-state Lithium-Ion Batteries (LIBs) have attracted great interest in recent years. In this regard, electrode deposition technology is expected to play an important role in the development of all-solid-state LIBs. We propose a new method for preparing a cathode film using a cold spray technique. In this study, LiCoO2 films were deposited using a cold spray technique. From SEM observations, the average thickness of the LiCoO2 films was estimated to be approximately 20 micrometers. Cyclic voltammetry showed the LiCoO2 film prepared with cold spraying to be electrochemically active. While the electric capacity of the LiCoO2 cathode film decreased monotonically until 70th cycle, it tended to give a relatively constant value after the 70th cycle. The cold spraying method may provide a useful route for the development of all-solid-state LIBs.
