It can be seen that the magnetic pressure from the middle to the end of discharge (2) is higher than that of the conventional product (CB), which uses electrolytic manganese dioxide adsorbed on the A group element system. This is due to the fact that the lithium was treated with chloride and neutralized with Lion (-therefore, the IA and IIA elements on the surface were removed (this is due to the fact that lithium is not adsorbed to the negative electrode surface).
