- This paper reports a high capacity lithium-sulphur (Li-S) battery cathode, based on packing monodisperse highly porous carbon nanospheres into interconnected clusters. This cathode achieved dense crack-free high areal sulphur loading (5 mg cm-2) with high electrical conductivity and low cathode impedance. The cathode delivers among the best reported volumetric capacity to date, above typical Li-ion areal capacity, with low capacity fading of 0.1% per cycle at 0.5 C over 500 cycles. It also shows the best gravimetric capacities published to date (670 mAh/g after 500 cycles). This simple-to-make cathode has the potential for large-scale Li-S battery applications.
