China team devises boron-doped carbon-sulfur aerogel with consecutive core-shell structures for high-capacity, long-life Li-S battery

Green Car Congress

Researchers at Jiangsu Normal University in China have devised a boron-doped carbon-sulfur (BCS) aerogel with consecutive “core-shell” stuctures as a binder-free cathode for lithium-sulfur batteries. These problems result in low specific capacity and poor cycling life of Li-S batteries.
