Key Points

The aim is to develop a SiO2@C anode that addresses issues of conductivity and volume expansion in lithium-ion batteries.
Constructed a covalently bonded Si–O–C structure
Characterized the electrode materials
Evaluated electrochemical performance in lithium-ion batteries
Increased conductivity observed in the SiO2@C anode
Enhanced capacity compared to traditional silica-based electrodes
Reduced volume expansion during cycling

Implication

Constructs a new SiO2@C anode to enhance conductivity and capacity in lithium-ion batteries, suggesting potential for improved commercialization.

Abstract

Silica-based materials, serving as one type of prospective electrode for advanced high-energy density LIBs (lithium-ion batteries), are encountering critical obstacles in commercialization, including inherently poor conductivity, volume expansion and particles...
