Nowadays, there is a huge demand for energy due to the population growth and technological progress. The researchers pay an intensive attention to the devices able to produce and store energy. Lithium-sulphur batteries represent this kind of device. Li-S batteries play a significant role in a development of rechargeable batteries. They are attractive adept due to their high theoretical capacity of sulphur (1672 mAh/g), abundance and non-toxicity of sulphur and low cost of sulphur. Li-S battery belongs to the conversion type of battery; it means new chemical compounds during electrochemical reactions. However, it is needed to solve some scientific problems, such as nonconductivity of sulphur and its volume increase during charge and discharge process [1, 2]. To solve these problems, composite materials based on sulphur are investigated. This work deals with sulphur/carbon composite as a cathode material for lithium-sulphur batteries. There are more forms of carbon which can be mixed with sulphur to improve the battery performance. Herein we report carbon microfibers prepared by electrospinning added to sulphur/CS2 solution as a composite cathode material.
