Abstract:<\/h4>\n
Gel polymer electrolytes (GPEs) present the best compromise between mechanical and electrochemical properties, as well as an improvement of the cell safety in the framework of Li metal batteries production. However, the polymerization mechanism typically employed relies on the presence of an initiator, and is hindered by oxygen, thus impeding the industrial scale\u2010up of the GPEs production. In this work, an UV\u2010mediated thiol\u2010ene polymerization, employing polyethylene glycol diacrylate (PEGDA) as oligomer, was carried out in a liquid electrolyte solution (1 M LiTFSI in EC\/DEC) to obtain a self\u2010standing GPE. A comparative study between two different thiol\u2010containing crosslinkers (trimethylolpropane tris(3\u2010mercaptopropionate) \u2010 T3 and pentaerythritol tetrakis(3\u2010mercaptopropionate) \u2010 T4) was carried out, studying the effects of the crosslinking environment and the GPE production methods on the cell performances. All the produced GPEs present an excellent room temperature ionic conductivity above 1 mS cm \u22121 , as well as a wide electrochemical stability window up to 4.59 V. When cycled at a current density of C\/10 for more than 250 cycles, all of the tested cells showed a stable cycling profile and a specific capacity >100 mAh g \u22121 , indicating the suitability of such processes for up\u2010scaling.<\/p>\n","protected":false},"excerpt":{"rendered":"
