1. A solid polymer electrolyte comprising:
a cellulosic polymer matrix, the cellulosic polymer matrix comprising a network of a cellulosic polymer;
lithium ions dispersed in the cellulosic polymer matrix;
ceramic particles dispersed in the cellulosic polymer matrix, wherein the ceramic particles comprise a metal oxide;
one or more plasticizers dispersed in the cellulosic polymer matrix; and
one or more polymer networks in contact with the cellulosic polymer matrix, the one or more polymer networks comprising a cross-linked acrylate-containing polymer, further comprising 25% to 60% by weight of the cellulosic polymer matrix, 10% to 25% percent by weight of the acrylate-containing polymer, 20% to 35% percent by weight of a source of the lithium ions, 2% to 7% percent by weight of the one or more plasticizers, and 10% to 25% percent by weight of the ceramic particles.
