Enhanced electrochemical properties of fluoride-coated LiCoO(2 )thin films

The electrochemical properties of fluoride-coated lithium cobalt oxide [LiCoO(2)] thin films were characterized. Aluminum fluoride [AlF(3)] and lanthanum fluoride [LaF(3)] coating layers were fabricated on a pristine LiCoO(2 )thin film by using a spin-coating process. The AlF(3)- and LaF(3)-coated f...

Sumario:The electrochemical properties of fluoride-coated lithium cobalt oxide [LiCoO(2)] thin films were characterized. Aluminum fluoride [AlF(3)] and lanthanum fluoride [LaF(3)] coating layers were fabricated on a pristine LiCoO(2 )thin film by using a spin-coating process. The AlF(3)- and LaF(3)-coated films exhibited a higher rate capability, cyclic performance, and stability at high temperature than the pristine film. This indicates that the AlF(3 )and LaF(3 )layers effectively protected the surface of the pristine LiCoO(2 )film from the reactive electrolyte.
