摘要 Background Thanks to the high theoretical capacity, silicon oxides (SiOx) hold great potential as anode materials for the next-generation high-performance lithium-ion batteries (LIBs). However, the low conductivity and substantial volume fluctuations of SiOx result in significant polarization and rapid capacity fading, greatly hindering its electrochemical performance and practical application. Methods To overcome the inherent challenges of SiOx, herein, a dual surface modification consisting of a carbon layer and conducting polymer layer is coated on SiOx. The process involves chemical vapor deposition (CVD) with C2H2 as the carbon source, followed by vapor-phase polymerization (VPP) to form high-quality carbon and poly(3,4-ethylenedioxythiophene) (PEDOT) layers on SiOx. Significant findings The dual-modified layers provide the resulting SiOx with enhanced electrical conductivity and improved structural stability. The modified SiOx demonstrates a high charge capacity of 1660.1 mAh/g at 0.1C, remarkable rate performance with the charge capacity of 945.0 mAh/g at 3C, and superior cycling span (∼812.7 mAh/g over 200 cycles). In addition, the modified SiOx demonstrates excellent compatibility with conventional graphite (GP) anode material, significantly enhancing its electrochemical performance.
