Abstract

See full text

A secondary battery cell includes a cathode of a first electrode material, an anode of a second electrode material, and a solid polymer electrolyte layer disposed between the cathode and anode. The solid polymer electrolyte includes a first surface in contact with the cathode and a second surface in contact with the anode. The solid polymer electrolyte layer includes a cellulosic polymer matrix. The cellulosic polymer matrix includes a network of the cellulosic polymer. Lithium ions are dispersed in the cellulosic polymer matrix. Ceramic particles are dispersed in the cellulosic polymer matrix. The ceramic particles include a metal oxide. One or more plasticizers are dispersed in the cellulosic polymer matrix. One or more polymer networks are in contact with the cellulosic polymer matrix. The one or more polymer networks include an acrylate-containing polymer.
