A method of preparing a gel type polymer electrolyte for a lithium-sulphur battery

摘要

The process for preparing a PEGDMA polyethylene glycol dimethacrylate gel-type polymer electrolyte is based on the fact that first of all a film by a photoinitiated PEGDMA cross-linking reaction and butyl methacrylate BMA is prepared. It is then soaked in an electrolytic solution of bis-trifluoromethanesulfonimide lithium salt of LiTFSI, where prior to mixing the mixture of PEGDMA with the photoinitiator and BMA, nanoscale silica nanoparticles SiO₂ are dispersed in the BMA. .
