Method for manufacturing lithium cobaltate oriented sintered plate
Provided is a method for manufacturing a lithium cobaltate oriented sintered plate, comprising (a) providing a green sheet comprising Co3O4 particles, (b) firing the green sheet to form a Co3O4 oriented sintered plate, and (c) firing the sintered plate in the presence of a lithium source to introduce lithium and thereby form the lithium cobaltate oriented sintered plate composed of LiCoO2, the method further comprising (d1) attaching a Mg-containing compound to the Co3O4 oriented sintered plate before the step (c) or (d2) attaching the Mg-containing compound to the lithium cobaltate oriented sintered plate after the step (c) to fire the sintered plate. According to the present invention, a lithium cobaltate oriented sintered plate can be manufactured in which grain boundaries in the plate thickness direction are significantly reduced and with which enhanced battery performance can be achieved when used as a positive electrode active material in lithium secondary batteries.
