A Comparative Study of Carbon Anodes Produced by Ball

The ball milling was carried out in a conventional planetary ball mill as well as in a high-energy ball mill. For graphite, our goal is to investigate the ball mill effect, so a high-energy ball mill was used to maximize the change. Whereas for layered graphene, due to the large particle size of the pristine material,
