Si@SiO2 nanowires/carbon textiles cable-type anodes for high-capacity reversible lithium-ion batteries

To fulfil the increasing demands for high-efficiency next-generation energy storage systems, different electrode matrixes have been designed to achieve the desired batteries with high energy density and long cycle life. Herein, we fabricated novel binder-free Si@SiO2 nanowires/carbon textiles cable-type anodes for Li-ion batteries applications. The half-cells based on the above electrodes delivered high reversible capacity of 2247 mA h g−1 at 800 mA g−1, good rate capability, and excellent cycle stability of as long as 1000 cycles at 8 A g−1. Full batteries including the as-synthesized Si@SiO2 anodes and commercial LiCoO2 cathodes were also fabricated, which exhibited greatly enhanced performance, thus revealing that these novel Si@SiO2 nanowires/carbon textiles cable-type electrodes can be applied in next-generation energy storage devices.
