In article number 1801573 , Guk‐Tae Kim, Zexiang Shen, Stefano Passerini and co‐workers report MnPO 4 ‐coated LiNi 0.4 Co 0.2 Mn 0.4 O 2 (MP‐NCM) as a cathode material for lithium‐ion batteries. The MnPO 4 coating acts as a protective layer physically preventing the contact between the NCM active material and the electrolyte, thus, stabilizing the electrode/electrolyte interface and preventing detrimental side reactions, eventually leading to a significantly enhanced rate capability and excellent cycling stability.
