Lithium/Sulfur rechargeable battery for power applications

锂/硫电池系统对于大规模电力应用是非常有前途的，因为它在各种类型的可充电电池中具有最高的能量密度和最低的成本。然而，Li/S电池的容量下降和循环寿命短一直是商业开发的问题。本项目的目的是研究容量衰减的机理，并开发有效的方法，如使用碳纳米管和纳米复合吸收剂来提高Li/S电池的循环寿命。预期成果是开发含硫阴极材料和聚合物电解质，使电动汽车成为技术上具有竞争力和环境上优越的上级运输选择。

The Lithium/Sulphur battery system is very promising for large-scale power applications as it has the highest energy density and lowest cost among various types of rechargeable batteries. However, the degradation of the capacity and short cycle life of Li/S battery have been problematic for commercial development. The aim of this project is to study the mechanisms of capacity fading and to develop effective means such as use of carbon nanotubes and nanosize composite absorbents to improve the cycle life of Li/S batteries. The expected outcomes are the development of sulphur-containing cathode materials and polymer electrolytes, enabling electric vehicles to be a technically competitive and environmentally superior transportation option.
