Note: The above are only the two most commonly used particle size specifications. We can provide products with other particle size specifications according to customer specific requirements.

 

4.  Recommendations 

 

This type of alloy is a medium-cobalt high-power product.

 

Compared with other types of low-cobalt alloy powder products, this type of alloy powder has the characteristics of high capacity, high platform and long life.

 

Note: Due to different processes, the above test results and parameters are only a reference for the design of the final battery product.
