Room temperature, liquid-phase Al2O3 surface coating approach for Ni-rich layered oxide cathode material

Abstract

A room temperature, atomic-layer-deposition-like coating strategy for NCM811 (80% Ni) is reported. Trimethylaluminum is shown to readily react with adsorbed moisture, leading both to Al2O3 surface layer formation on NCM811 and to trace H2O removal in a single treatment step. Even more importantly, the cycling performance of pouch cells at 45 °C is greatly improved.
