In Situ Generation of a Gel Polymer Electrolyte via the Controlled Formation of Ethylene Carbonate in a Poly(ethylene carbonate)‐Hydrogenated Nitrile Butadiene Rubber Solid Polymer Electrolyte (Adv. Sustainable Syst. 7/2024)

Gel Polymer Electrolytes In article number 2400027, Mickael Dollé and co-workers develop an innovative waste-free method for converting solid polymer electrolytes with low ionic conductivity into electrolytes with enhanced electrochemical performance. The initial solid polymer electrolyte is produced via solvent-free melt processing. Heat-induced in situ decomposition of the conductive phase yields a gel polymer electrolyte with high lithium ion mobility and promising electrochemical performance.
