“…The processing time with organic non-solvent, that is, the phase conversion time of the carrier film, has a great influence on the porosity of the phase conversion film [31], thus greatly affecting the mechanical strength of the phase conversion membrane and the properties of the polymer electrolyte formed by the membrane [32]. In this paper, the effect of the phase transition time on the properties of the carrier film and polymer electrolytes is explored.…”

To optimize the preparation process of polymer electrolytes by in situ UV curing and improve the performance of polymer electrolytes, we investigated the effect of carrier film phase conversion time on the properties of polymer electrolyte properties in all-solid-state LIBs. We compared several carrier films with phase conversion times of 24 h, 32 h, 40 h, and 48 h. Then, the physical properties of the polymer electrolytes were characterized and the properties of the polymer electrolytes were further explored. It was concluded that the carrier membrane with a phase transition time of 40 h and the prepared electrolyte had the best performance. The ionic conductivity of the sample was 1.02 × 10−3 S/cm at 25 °C and 3.42 × 10−3 S/cm at 60 °C. At its best cycle performance, it had the highest discharge-specific capacity of 155.6 mAh/g, and after 70 cycles, the discharge-specific capacity was 152.4 mAh/g, with a capacity retention rate of 98% and a discharge efficiency close to 100%. At the same time, the thermogravimetric curves showed that the samples prepared by this process had good thermal stability which can meet the various requirements of lithium-ion batteries.
