Abstract
A solid polymer electrolyte precursor composition includes (i) one or more organic solvents; (ii) one or more cellulosic polymers dissolved in the organic solvent(s); (iii) one or more polymerizable components dissolved or dispersed in the organic solvent(s); (iv) one or more photo-initiators dissolved or dispersed in the organic solvent(s), where at least one of the one or more photo-initiators, following irradiation with light, promotes polymerization of at least one of the one or more polymerizable components; (v) one or more lithium ion sources dissolved or dispersed in the organic solvent(s); (vi) one or more plasticizers dissolved or dispersed in the organic solvent(s); and (vii) one or more ceramic particles dissolved or dispersed in the organic solvent(s).
