2、Anode Materials

 

 
Anode Materials Li-ion Button Cell Samples

 

Advantages:

  1. Most of the graphite products from Dawudian deposit will be anode materials due to the excellent electrochemical performance;

  2. Some performances are better than that of existing anode materials;

  3. The yield is 60% , higher than average level of the industry (40%).

Applications:Anode Materials of EV Power Battery and Energy Storage Battery.
