JACS最新锂电文章:Silicon Nanowire Fabric as a Lithium Ion Battery Electrode Material


A non-woven fabric with paper-like qualities composed of silicon (Si) nanowires is reported.  
The nanowires—made by the supercritical fluid-liquid-solid (SFLS) process—are crystalline,
range in diameter from 10 to 50 nm with average length over 100 m and are coated with a thin
chemisorbed polyphenylsilane shell.  About 90% of the nanowire fabric volume is void space.  
Thermal annealing of the nanowire fabric in a reducing environment converts the
polyphenylsilane coating to a carbonaceous layer  that significantly increases the electrical
conductivity of the material.   This makes the nanowire fabric useful as a self-supporting,
mechanically flexible high-energy storage anode material in  a lithium ion battery.  Anode
capacities of more than 800 mA h/g are achieved without the addition of carbon binder.
