Core-shell Architecture Strategy of Improving the Electrochemical Performance of the Li-rich Layered Oxides: A Review

Abstract

Lithium-ion battery (LIB) serves as power supply for suitable electronics and stationary electrical systems (storage) as a result of their outstanding combination of extraordinary densities (power and energy). The cathode constitutes an integral part of LIBs and its property determines the performance of the battery. The layered lithium-rich oxide (LLO) is unique and favourable cathode materials for LIBs as a result of its high capacity compared to conventional cathode materials such as LiNiO2etc. However, they demonstrate several performance limitations such as low first cycle efficiency and poor cycling stability thus, limiting their practical applications. Therefore, this review discussed a core-shell architecture strategy of enhancing the electrochemical performance of the LLOs materials for LIBs.
