Enhanced Electrochemical Performance of the Lithium-Manganese-Rich Cathode for Li-Ion Batteries with Na and F CoDoping.

The lithium-manganese-rich layered oxide cathode (LMR-NMC), LiMnO·(1 - )LiMO (M = Co, Ni, and Mn), is on demand because of its high specific capacity of over 250 mA h g between the voltage range 2.0-4.8 V (vs Li/Li).
