ROOM-TEMPERATURE FABRICATION OF LITHIUM COBALT OXIDE THIN-FILM ELECTRODES BY LITHIUM HYDROXIDE SOLUTION TREATMENT

An economical, energy-efficient, and environmentally friendly solution process was used to prepare lithiated thin-film electrodes as a catho de for lithium rechargeable microbatteries. Well-crystallized and elec trochemically active lithium cobalt oxide thin-film electrodes were sp ontaneously fabricated in a single synthetic step in a 4M lithium hydr oxide solution at room temperature without any postsynthesis annealing . The estimated film properties show that the obtained spinel lithium cobalt oxide films (space group Fd3m) has possible use as a desired ca thode film.
