Abstract
En 中文
• The initial Coulombic efficiency of the NG anode was improved by decreasing its specific surface area. • LiAlO2 not only significantly reduces interfacial resistance but also improves the affinity for lithium. • The LiAlO2 layer promotes an Al-F/LiF-enriched SEI with elevated electron work function. • Remarkable capacity retention of 80.3 % is obtained after 800 cycles at 4C charge-discharge rate.
