PLATE-LIKE PARTICLE FOR CATHODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY, CATHODE ACTIVE MATERIAL FILM FOR LITHIUM SECONDARY BATTERY, METHODS FOR MANUFACTURING THE PARTICLE AND FILM, METHOD FOR MANUFACTURING CATHODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY, AND LITHIUM SECONDARY BATTERY

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.
