Lithium-sulfur batteries are next-generation battery systems with low cost and high specific energy. However, it is necessary to solve several deficiencies of these batteries such as shuttle effect, and gel polymer electrolyte is a great candidate. These perspective materials can be used as a replacement for liquid electrolytes, and at the same time, they can help to solve the problems of lithium-sulfur batteries. In this work, gel polymer electrolyte (GPE) based on methyl methacrylate was prepared by cross-linking strategy. As cross-link ethylene glycol dimethacrylate (EDMA) was used. Prepared gel with a high electric conductivity was testing in the lithium-sulfur cell (Li/GPE/S). The electrochemical performance of the cell was studied.
