This project aims to develop silicon-based cathode materials for high-performance RT-sodium/sulphur batteries. These are expected to improve the sulphur electroactivity with sodium and supress the shuttle effect, achieving high energy density and cycling stability. This project will accelerate the sluggish electrochemical reactions between sulphur and sodium by embedding sulphur in hollow mesoporous carbon nanospheres, and modify the surface of the mesoporous carbon nanospheres’ host. A superior RT-sodium/sulphur battery with high energy density, a long cycling life, and stationary storage has potential to shift fossil fuels towards renewable energy system to power the economy in the long run.

该项目旨在开发用于高性能RT-钠/硫电池的硅基阴极材料。这些有望改善硫与钠的电活性并抑制穿梭效应，实现高能量密度和循环稳定性。该项目将通过将硫嵌入中空介孔碳纳米球中来加速硫和钠之间缓慢的电化学反应，并对介孔碳纳米球的主体进行表面改性。具有高能量密度、长循环寿命和固定存储的上级RT-钠/硫电池具有将化石燃料转向可再生能源系统的潜力，从而从长远来看为经济提供动力。
