Cobalt-intercalated layered manganese oxide

MnO has been also coated with PANl to improve its electrochemical performance. Shin et al found that the cobalt-intercalated layered manganese oxide (CLMO) displayed the excellent cyclability over 40 cycles, although it exhibited a low discharge capacity (143 mA h g at 40 mA g current density) [51]. After chemical oxidative polymerization of aniline...

Unlike cobalt and nickel, manganese does not form a stable, pure LiMn02 phase and forms the spinel structure instead, named after the mineral of spinel (Table 1.3) with the composition of Lio.5Mn02, conunonly expressed as LiMn204. Manganese-based cathode materials are attractive mainly due to their low cost compared to cobalt and nickel. A wide variety of the hthiated manganese oxides with multiple structures and compositions (Li Mn 0 ratios) exist and many of these compounds can reversibly intercalate lithium, but amongst these materials, spinel materials and the layered derivatives are the most mature, to the point of commercial availability. Spinel-stractured materials will be discussed separately in the next part of this chapter.
