Recent advances in cathode materials for sustainability in lithium
Spinel LiNi 0.5 Mn 1.5 O 4, with its voltage plateau at 4.7 V, is a promising candidate for next-generation low-cost cathode materials in lithium-ion batteries. Nonetheless, spinel materials face limitations in cycle stability due to electrolyte degradation and side reactions at the electrode/electrolyte interface at high voltage.
