Abstract (en)
[origin: WO2021074074A1] The present invention relates to a solvent-free solid electrolyte for an alkali metal solid battery comprising an alkali metal conducting salt and a semi-interpenetrating network (sIPN) consisting of a cross-linked and a non-crosslinked polymer, wherein the semi-interpenetrating network consists of a non-cross-linked polymer selected from the group consisting of polyethylene oxide (PEO), polycarbonate (PC), polycaprolactone (PCL), chain-end-modified derivatives of said polymers or mixtures of at least two components thereof and the cross-linked polymer comprises polyethylene glycol dimethacrylate (PEG-dMA). The invention furthermore relates to a method for producing a solid electrolyte and an alkali metal battery having the solid electrolyte according to the invention.
