Lithium ion batteries are made of four main components: the nonaqueous electrolyte, graphite for the anode, LiCoO2 for the cathode, and a porous polymer separator. In the manufacturing process, the polymer separator must be porous, with a controlled porosity. The four main materials are in turn mixed in various proportions to create the lithium-ion battery.
