Title:
炭素被覆正極材料及びその製造方法
Document Type and Number:
Japanese Patent JP7375056
Kind Code:
B2
Abstract:
A carbon-coated cathode material (3) and a preparation method thereof. The carbon-coated cathode material (3) includes a lithium metal phosphate particle (P) and a carbon coating layer (C). The carbon coating layer (C) is coated on the lithium metal phosphate particle (P). The carbon coating layer (C) is formed by a first heat treatment and a second heat treatment. A first carbon source is added in the first heat treatment, and a second carbon source is added in the second heat treatment. The first carbon source has a first weight percentage relative to the lithium metal phosphate particle (P). The second carbon source has a second weight percentage relative to the lithium metal phosphate particle (P). The first weight percentage of the first carbon source is equal to or less than the second weight percentage of the second carbon source.
