PLATE-SHAPED PARTICLES FOR POSITIVE ELECTRODE ACTIVE MATERIAL OF LITHIUM SECONDARY BATTERIES, LITHIUM SECONDARY BATTERY POSITIVE ELECTRODE ACTIVE MATERIAL FILMS, MANUFACTURING METHOD THEREFOR, LITHIUM SECONDARY BATTERY POSITIVE ELECTRODE ACTIVE MATERIAL MANUFACTURING METHOD AND LITHIUM SECONDARY BATTERIES

摘要

An object of the present invention is to provide a lithium secondary battery which has improved capacity, durability, and rate characteristic as compared with conventional lithium secondary batteries. A plate-like particle or a film for a lithium secondary battery cathode active material has a layered rock salt structure. The (003) plane is oriented in a direction intersecting the direction of the plate surface of the particle or film.
