摘要

A sulfur cathode with high capacity per area (>7 mA h cm(-2)) and high sulfur loading (6.7 mg cm(-2)) was fabricated by synthesizing a carbon fiber cloth-sulfur composite via a simple method. It is worth noting that an ingenious method is adopted which can improve the performance of Li-S batteries by forming in situ polysulfide ions.
