POSITIVE ELECTRODE MATERIAL, PREPARATION METHOD THEREOF, AND SECONDARY BATTERY INCLUDING SAME - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18326025 Titled 'POSITIVE ELECTRODE MATERIAL, PREPARATION METHOD THEREOF, AND SECONDARY BATTERY INCLUDING SAME'
Simplified Explanation
The abstract describes a positive electrode material for batteries. It consists of a core and a shell layer. The core has a molecular formula of LiNiCoMnM1O, where x is between 0.8 and 1.0, y is between 0 and 0.2, a is between 0 and 0.1, z is between 0 and 0.1, and M1 can be Al, Ta, or B. The shell layer has a molecular formula of LiCoA1NbM2O, where m is between 0.85 and 1.0, n is between 0 and 0.15, b is between 0 and 0.1, 1-m-n is between 0.001 and 0.02, c is between 0 and 0.05, and M2 can be W, Mo, Ti, Zr, Y, or Yb.
