Abstract

Abstract : Lithium-sulphur batteries are one of the most promising areas in the development of batteries based on lithium. If the problems associated with them will be solved they could be a very attractive secondary energy sources mainly for electromobility due to their high gravimetric energy density. One of the main disadvantages of the lithium-sulphur batteries is the deposition of polysulfide on the surface of the lithium anode leading to loss of capacity during cycling. As a solution to this problem, a carbon fibres structure was used in this article, which will absorb these polysulfide and this will consequently slow down the decline of capacity and increase stability and capacity in higher C-rate.
