INQUIRY

Lithium-sulfur battery is the next generation of high energy density electrochemical energy storage device, the carbon and sulfur composite positive electrode double-sided electrode plate is the key component to improve its performance. This electrode sheet uses advanced carbon-sulfur composite technology to effectively compound highly conductive carbon materials with sulfur through a carefully designed structure. Carbon materials not only provide a good conductive network for sulfur, but also effectively limit the volume expansion of sulfur during charge and discharge through its porous structure, and reduce the shuttle effect of soluble polysulfide ions, thus significantly improving the cycle stability and energy density of the battery.
