Researchers optimize the assembly of micro-/meso-/macroporous carbon for Li-S batteriesLi-S batteries are considered as promising alternatives for Li-ion batteries in the new generation of energy storages, due to high specific capacity (1675 mAh/g) and energy density (2600 mWh/g) of sulfur. But the poor conductivity of sulfur and severe shuttle effect of reaction intermediates destory the stability of this system. A variety of porous carbon materials have been applied as sulfur hostææææææ
