3M™ Battery Cathode Materials
3M™ Battery Cathodes are mixed metal layered oxides comprising of Manganese, Nickel, and Cobalt. They have improved thermal stability and up to six times less Cobalt for reduced price volatility when compared to the industry standard Lithium Cobalt Oxide. 3M offers three cathode products - BC-618, BC-718, and BC-723. 3M has developed these proprietary cathode powder formulations with precise control of structure and compositions tailored for both energy and power applications.
Features and Benefits:
- Thermally stable
- Excellent electrochemical properties
- Uniform particle size, shape and morphology and good density
- Up to six times less cobalt than Lithium Cobalt Oxide
- Compatible with most existing battery manufacturing processes
