Abstract

Being considered as one of the most potential cathode materials, Li_1.15Ni_0.17Co_0.11Mn_0.57O₂ draws plenty of attention towards its optimization on cycling and rate performance. The surface coating process provides a longer cycling life and better rate performance for the cathodes. A systematic investigation has been carried out on the nano-AlPO₄ coating layer for the Li_1.15Ni_0.17Co_0.11Mn_0.57O₂ cathode material through a facile in situ dispersion process. The 1% coated cathode material can hold about 90% capacity retention after 100 cycles. Besides, the surface coating enhances the rate ability of Li_1.15Ni_0.17Co_0.11Mn_0.57O₂, which holds a reversible capacity of 202.3 mAh g^-1 at the rate of 1C. Surface information is collected during cycling, which reveals that less side reactions occur on the electrode-electrolyte interface after the coating process for improved cycling and rate performance.
