Cathode active material, method of preparing the same, and cathode and lithium battery containing the material |
摘要 |
Composite cathode active materials having a large diameter active material and a small diameter active material are provided. The ratio of the average particle diameter of the large diameter active material to the average particle diameter of the small diameter active material ranges from about 6:1 to about 100:1. Mixing the large and small diameter active materials in a proper weight ratio improves packing density Additionally, including highly stable materials and highly conductive materials in the composite cathode active materials improves volume density, discharge capacity and high rate discharge capacity.
