POSITIVE ELECTRODE ACTIVE MATERIAL PARTICLE, LITHIUM ION SECONDARY BATTERY AND METHOD FOR PRODUCING POSITIVE ELECTRODE ACTIVE MATERIAL PARTICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18326483 titled 'POSITIVE ELECTRODE ACTIVE MATERIAL PARTICLE, LITHIUM ION SECONDARY BATTERY AND METHOD FOR PRODUCING POSITIVE ELECTRODE ACTIVE MATERIAL PARTICLE
Simplified Explanation
The abstract describes a patent application that focuses on improving the rate characteristic of a positive electrode active material particle used in batteries. The particle has an O2-type structure and consists of transition metal elements (Mn, Ni, and Co), Li, and O. There are two modes of the particle:
- First mode: Spherical positive electrode active material particle with an O2-type structure.
- Second mode: Positive electrode active material particle with at least one shell and at least one void in the cross-sectional structure. The shell has an O2-type structure and consists of transition metal elements (Mn, Ni, and Co), Li, and O. The surface of the shell has crystallites, and the void is present along the inner wall of the shell.
Potential applications of this technology:
- Battery manufacturing industry
