graphene is used as the cathode in a graphene battery.The amount of graphene incorporated into the electrode is usually based on the performance requirements and depends upon the existing efficiencies and/or weaknesses of the solid-state precursor material.
Graphene can make batteries that are light, durable and suitable for high capacity energy storage, as well as shorten charging times. It will extend the battery’s life-time, which is negatively linked to the amount of carbon that is coated on the material or added to electrodes to achieve conductivity.
This technology will be the double life of the batteries
i apolpgize for the answer and thanks
I apologize this is not my specialist , thank you for invitation
