Abstract
There is provided an electrochemical cell which has a non-metal negative electrode (anode on discharge). That is, no solid metal active material is used. The active material of the anode is lithium manganese oxide, Li.sub.x Mn.sub.y O.sub.z. According to another aspect of the invention, both the anode and cathode are formed of lithium manganese oxide, such as Li.sub.x Mn.sub.2 O.sub.4, where the starting material for both the anode and cathode has a value of x in a range of 1.ltoreq.x.ltoreq.3.
