Unravelling the Role of Electrochemically Active FePO₄ Coating by Atomic Layer Deposition for Increased High-Voltage Stability of LiNi_0.5Mn_1.5O₄ Cathode Material.

ABSTRACT: Ultrathin amorphous FePO₄ coating derived by atomic layer deposition (ALD) is used to coat the 5 V LiNi_0.5Mn_1.5O₄ cathode material powders, which dramatically increases the capacity retention of LiNi_0.5Mn_1.5O₄. It is believed that the amorphous FePO₄ layer could act as a lithium-ions reservoir and electrochemically active buffer layer during the charge/discharge cycling, helping achieve high capacities in LiNi_0.5Mn_1.5O₄, especially at high current densities.
