The main commercial application of lithium batteries is graphite, that is, carbon, and copper foil is used to conduct current without reaction. Another safe cathode material is Li4Ti5O 12 lithium titanate, which is safer because its reaction voltage relative to Li/Li+ is about 1.5V, and there is no potential safety hazard caused by the deposition of metallic lithium on its surface. At present, anode materials used in industrial production mainly include nano-silicon and part of nano-titanium dioxide.

If it is in the research field, there are too many negative electrode materials, and some people use graphene as the negative electrode material or lithium alloy.
