 A phase change mediation combined with cord reinforcing concept is proposed to improve the electrical conductivity and flexibility of CO-anode materials by fabricating graphing cord in situ with C and SiO2 nanodomains generated in the CO matrix via chemical vapor deposition. The increased SiO2 regions alleviate volume change, enhance tenacity, and contribute to additionally plus storage and pledge more channels for Li-plus transfer and electrolyte wedding. The as fabricated SiO at gra anodes deliver a high reversible capacity of 1,127 mAh G-1 at 0.2A G-1 with 87% capacity retention after 200 cycles, deepening the understanding of the electrochemical reaction mechanism of Li-plus in SiO and inspiring a rational design tactic for advanced lithium ions batteries.
