Investigation of New Conductive Carbon Materials for Lithium-Sulfur Batteries

近年来，锂硫电池引起了人们的极大兴趣，主要是因为它们的理论比能量是锂离子系统的几倍。然而，由于硫是一种电绝缘体，导致性能不佳，因此锂硫电池存在内阻高的问题。本文旨在确定在含硫阴极中使用两种不同的导电碳材料组合的可行性，以产生结构改进的阴极，从而提高导电性。我们的目标是在锂硫电池中测试这种阴极，以显示更低的内阻和更好的性能。

Lithium-Sulfur batteries have been of great interest in recent years due primarily to their theoretical specific energy being several times greater that of Li-ion systems. However, Lithium-Sulfur batteries suffer from the issue of high internal resistance due to fact that sulfur is an electrical insulator resulting in poor performance.Here OXIS aim to determine the feasibility of using a combination of two different conductive carbon materials within the sulfur containing cathode in order to produce cathodes with a modified structure and hence improved electrical conductivity. We aim to demonstrate testing of such cathodes within Lithium-Sulfur pouch cells to show lower internal resistance and improved performance.
