제목 Synthesis of In-situ gel polymer electrolyte with Lithium bis(fluorosulfonyl)imide(LiFSI) and 1,3-dioxolane(DOL) used by Lithium Ion batteries
초록 In general, Solid polymer electrolyte or inorganic solid electrolyte often exhibit high ionic conductivity at room temperature. Despite its advantages, ISE has not been widely used in high energy lithium batteries due to its brittleness and extremely poor electrode/electrolyte contact. Therefore, in-situ polymerization of polymer electrolytes effectively solves the above-mentioned problems. During the in-situ polymerization process, the monomer, plasticizer, lithium salt and initiator are combined into a precursor solution, and then the precursor solution is injected into the lithium battery. After the precursor is polymerized in situ under certain external conditions to obtain a gel/solid polymer lithium battery. Another solvent commonly used in Li batteries, known as in-situ polymerization reactions, is 1,3-dioxolane (DOL). In this paper, we studied the effect of LiFSI as a catalyst and investigated its effect on polymerization.
