Abstract
The increasing demand for energy storage in recent years requires higher energy of lithium-ion batteries (LIBs). The recent development of electrode materials, such as layered oxide cathodes and Si based anodes, with high theoretical capacity and appropriate working voltage, creates great potential to meet the requirements for higher energy density. However, the development of high-energy electrode materials has been plagued by their persistent surface degradation and structural fatigue issues in batteries. Layered oxide cathodes experience abrupt strain accumulation caused by inherent anisotropic lattice changes, leading to the generation of intergranular and intragranular cracking. Moreover, their intrinsic high reactivity with electrolyte at the highly delithiated state suffers from serious surface reconstruction, including interfacial side reaction and phase transition. In terms of the anode, large volume change and deteriorated solid-electrolyte interphase of Si anode result in the pulverization of Si particles the increase in cell impendence. This talk mainly concentrates on the advanced interface design to tackle the challenges of high-energy electrode materials for next-generation batteries.
