Comparison of various conductive agents(Carbon black, carbon nanotubes or graphene) for lithium ion batteries
In the current commercial lithium-ion battery system, the limiting factor is mainly the electrical conductivity. In particular, the insufficient conductivity of the positive electrode material directly limits the activity of the electrochemical reaction. It is necessary to add a suitable conductive age...
