Nano Sulfur Composite for Li/S Polymer Secondary Batteries

Abstract:

Article Preview

The Li/S polymer secondary batteries presents higher capacity, lower materials cost and much better performance in higher operation temperature. A nano-scale sulfur polymer composite cathode material has been developed for these batteries, and its cycle capacity is over 700mAh/g when the lithium metal is used as the anode; A nano-scale Cu/Sn alloy powder has been synthesized by a novel micro-emulsion process, its cycle capacity is over 300 mAh/g; The performance of PVdF gel electrolyte has been improved through the addition of the nanometer SiO2 synthesized in-situ. The advanced Li/S polymer secondary batteries will be a promising alternative for next generation energy storage system.
