Anodes of Li[sub 4]Mn[sub 5]O[sub 12], and Li[sub 4]Ti[sub 5]O[sub 12] with a spinel-type structure have been evaluated in room-temperature lithium cells. The cathodes that were selected for this study were the stabilized spinels, Li[sub 1.03]Mn[sub 1.97]O[sub 4] and LiZn[sub 0.025]Mn[sub 1.95]O[sub 4], and layered LiCoO[sub 2]. The electrochemical data demonstrated that Li[sup +] ions will shuttle between two transition-metal host structures (anode and cathode) at a reasonably high voltage with a concomitant change in the oxidation state of the transition metal cations so that the Li[sup +] ions do not reduce to the metallic state at the anode during charge. These cells reduce the safety hazards associated with cells containing metallic-lithium, lithium-alloy, and lithium-carbon anodes.
