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

摘要

Provided are lithium secondary batteries wherein capacity, durability and rate characteristics are improved compared to the past. The plate-shaped particles or films for the positive electrode active material of lithium secondary batteries comprise cobalt and lithium and have a layered rock salt structure. The (003) face is oriented to intersect with the plate surface.
