✦ Synopsis

An LiNOy-MnO, mixture, heat treated in the presence of HsO, or IWO,, has shown excellent rechargeability as an electrode material for rechargeable lithium batteries. XRD patterns of this compound are completely different from known Li-Mn composite oxides such as LiMn,O, or Li,MnO,. The presence of HzOz or HN03 preferentially reduces the LiMn,O, content. The physicochemical properties of this new compound have been compared with those of other types of Li-Mn composite oxides.
