In addition, the key issues encountered by many Mn-based materials, including Jahn–Teller distortion, Mn dissolution, crystal water, impact of electrolyte, etc., are also discussed. Finally, challenges and perspectives on the future development of manganese-based materials are provided as well.
A large variety of materials have been synthesized and evaluated as cathode materials for LIBs.
