Abstract

Development of advanced energy-storage batteries for portable electronic devices and electric vehicles must accomplish several requirements: safety, low-cost, nature friendly, long lifecycle, high energy density, and high theoretical capacity. Lithium-sulfur batteries can execute these requirements. However, the practical application of lithium-sulfur battery is hindered by several major disabilities, such as volumetric expansion of sulfur, structural instability, high self-discharging, poor electronic conductivity of sulfur, and low cycle life. This article deals with different types of carbons as additives in cathode for lithium-sulfur battery.
