Abstract

En 中文
• A phase-compatible surface engineering strategy by fabricating a spinel ionic conductor coating layer together with Cr/Ti co-doping is proposed to modify Li-rich layered oxides (LLOs) • The optimal LCTO-LLOs-1 exhibits a capacity retention of 85.6% and voltage decay of 0.309 mV/cycle after 500 cycles at 1 C. • The LCTO surface modification is beneficial to construct a stable surface structure, effectively suppressing oxygen release and interface side reactions.
