the reactor while being stirred the mixed solution was stirred and heated to 50 u00b0 c and the reaction proceeded for 4 hours at this temperature to produce an organosilicon polymer then 0 020 mol of nano li 4 ti 5 o 12 less than 100 nanometers was added and a sand milling process was carried out for 2 hours at the room temperature to obtain the organosilicon polymer solid electrolyte preparation of lithium methoxide 0 200 mol of lithium metal was added into 200 ml of methanol to react completely to produce a lithium methoxide solution synthesis of an organosilicon polymer solid electrolyte 100 ml of methanol was added into a stirred tank reactor as a solvent 0 150 mol of ch 3 si och 3 3 and 0 050 mol of ch 3 2 si och 3 2 were added into the reactor then the methanol solution of the lithium methoxide was added then 0 300 mol of was added into the reactor while being stirred the mixed solution was stirred and heated to 80 u00b0 c and the reaction proceeded for 4 hours at this temperature to produce an organosilicon polymer the organosilicon polymer was used to directly prepare the organosilicon polymer solid electrolyte preparation of lithium methoxide 0 200 mol of lithium metal was added into 200 ml of methanol to react completely to produce a lithium methoxide solution synthesis of an organosilicon polymer solid.
