10g Mesoporous Nano Carbon for Lithium-Sulfur Battery

Rechargeable lithium–sulfur (Li–S) batteries have recently become one of the most promising energy storage systems due to the low-cost and high-specific energy of sulfur cathodes. The practical application is still hindered by many material challenges, including dissolution of intermediate lithium polysulfides (Li2Sxx>3) in the electrolyte, large volumetric expansion (80%) of sulfur upon lithiation, and poor electronic/ionic conductivity of sulfur and lithium sulfide (Li2S). 

Mesoporous carbon has large specific surface area and pore capacity, good electrical conductivity and structural stability, controlled pore size distribution and ordered pore structure, which can effectively improve the utilization of sulfur and the cycling performance of batteries. The composites of ordered mesoporous carbon and sulfur can obtain better electrochemical performance. The small load of mesoporous cabron can help to inhibit the diffusion of polysulfide ions and facilitate the transport of lithium ions during the charge and discharge. In addition, the large pore capacity can increase the sulfur loading and improve the initial discharge capacity and cycling performance of the battery.
