What is Enhanced Electrochemical Performance and Thermal Stability of ZrO~2~- and rGO–ZrO~2~-Coated Li[Ni~0.8~Co~0.1~Mn~0.1~]O~2~ Cathode Material for Li-Ion Batteries about?

LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM811) has been considered as a promising cathode for Li-ion batteries (LIBs) due to its high electrochemical capacity and low cost; however, poor cycling stability is one of the main restricting factors in industrial applications of the NCM811 cathode material. Notably, the capacity fading and low structural stability of NCM811 are intensified at elevated temperatures. ZrO 2 -and composite rGO-ZrO 2 -coated NCM811 were fabricated by a facile wet chemical method and evaluated at 25 and 55 °C to overcome these impediments. The ZrO 2 coating provides superior cycling and thermal stability and perfectly protects the cathode active material from deleterious side reactions, and HF attacks by suppressing the direct contact of NCM811 particles and electrolytes. Despite these advantages, the discharge capacity of the ZrO 2 -coated cathode material (166.3, 187.7 mAh g -1 ) is slightly lower than that of the pristine cathode (171.7, 193.0 mAh g -1 ) due to the insulative nature of ZrO 2 NPs, after one cycle at ambient and elevated temperatures. The first cycle discharge capacity increased to 185.9 and 206.7 mAh g -1 at 25 and 55 °C, respectively, with the rGO-ZrO
