The top ten brands of mobile phone batteries are Panasonic, Nanfu, Speedmaster, Shuanglu, Chaowei, Tiannen, Pinsheng, SONY, Desai, millet, graphene is a carbon elemental, with a high specific surface area, good thermal conductivity, electrical conductivity, chemical stability and half integer quantum Hall effect.
At present, mobile phone batteries are mainly based on ternary lithium batteries, graphene battery batteries are of course the last, but at present graphene batteries are still in the research and development stage, and industrialization will take quite some time.
