Tuning of Ni, Mn, and Co (NMC) Content in 0.4(LiNixMnyCozO2)·0.4(Li2MnO3) toward Stable High-Capacity Lithium-Rich Cathode Materials

Li-rich cathode materials can offer a high specific capacity of ≥250 mA h g–1; however, the major issues are their structural instability, capacity degradation, and voltage decay upon prolonged cyc...
