Abstract

A strategy of reinforced PPy wrapping over an acetylene black-coated sulfur composite (PPy–AB/S) was designed for synthesizing cathode materials of Li–S batteries with improved performance. It was found that the resulting PPy–AB/S cathodes were able to maintain 630 mA h g−1 even after 200 charge–discharge cycles at a rate of 0.5 C.
