Enhanced Electrochemical Properties of Gradient Cathode Material By Coating
One promising approach to resolve these stringent shortcomings of high-voltage cathode materials is the surface modification using inorganic coating materials such as Al2O3 and ZrO2, ZnO, AlF3, Ni3(PO4)2, and AlPO4 on the result products. The process for the material preparation involve calcining the lithium source precursor such as LiOH, Li2CO3, LiNiO2 etc with another precursor such as Co3O4, Co(OH)2, LiNi1/3Mn1/3Co1/3(OH)2, Ni0.8Co0.15Al0.05O2, Ni0.25Mn0.75CO3 etc at high temperature. The coating process happens at results material, which would have a distinctively separation between bulk material with the coating layer. We coat the material on the precursor, and then use the coating precursor to prepare the cathode material.
