Unravelling the Role of Electrochemically Active FePO(4) Coating by Atomic Layer Deposition for Increased High‐Voltage Stability of LiNi(0.5)Mn(1.5)O(4) Cathode Material

Ultrathin amorphous FePO(4) coating derived by atomic layer deposition (ALD) is used to coat the 5 V LiNi(0.5)Mn(1.5)O(4) cathode material powders, which dramatically increases the capacity retention of LiNi(0.5)Mn(1.5)O(4). It is believed that the amorphous FePO(4) layer could act as a lithium‐ions...

Sumario:Ultrathin amorphous FePO(4) coating derived by atomic layer deposition (ALD) is used to coat the 5 V LiNi(0.5)Mn(1.5)O(4) cathode material powders, which dramatically increases the capacity retention of LiNi(0.5)Mn(1.5)O(4). It is believed that the amorphous FePO(4) layer could act as a lithium‐ions reservoir and electrochemically active buffer layer during the charge/discharge cycling, helping achieve high capacities in LiNi(0.5)Mn(1.5)O(4), especially at high current densities.
