Nowadays, the practical application of Li-S batteries is still inhibited by its inferior cycle stability caused by the shuttle effect. Herein, we report the design and fabricate of a fishbone based porous carbon (FBPC) for ultralong cycle life Li-S batteries. Prepared by carbonizing the tuna bone with activation process, FBPC is a heteroatoms-doped hierarchical porous carbon material which owns following...
Lithium-sulfur (Li-S) battery is regarded as one of the most promising candidates for developing advanced energy storage system, but the polysulfide shuttle effect remains the biggest obstacle for its practical application. In this work, nano-hydroxyapatite (Ca5(PO4)3(OH)) was used as an additive in the sulfur cathode and carbon-coated separator to prevent the polysulfide shuttle effect and thus to...
