Procedure

Polymer Electrolyte: Five grams (g) of propylene carbonate, 5 g of poly(ethylene glycol)diacrylate (Mn=700), 1 g of lithium trifluoromethanesulfonate (“Litrif”), and 17.5 milligrams (mg) of dimethoxyphenylacetophenone (“DMPAP”) were added together and sonicated for 15 minutes until dissolved. The electrolyte is a colorless to light yellow liquid before UV exposure and a transparent gel afterwards. All chemicals were purchased from Sigma-Aldrich and used as received.
