Electrolyte distribution — One of the key factors to improve the high-rate performance of gel polymer Li ion batteries

Novel polysilsesquioxane hybrid polymer electrolytes for lithium ion batteries

“…[46][47][48] Furthermore, the homogeneity of the GPE may also be a contributing factor for the cell to maintain good cycling ability. 49 The cycling performance of the cells was also evaluated through measuring the discharge capacities shown in Fig. 8, where the cells were charged at a current density of 0.5 C and discharged at a 1.0 C. As expected, the cells with gel polymer electrolyte continued to maintain greater discharge capacity as compared with that of the liquid electrolyte, suggesting the improved cycling stability provided by the gel matrix.…”

Gel electrolytes based on an ether-abundant polymeric framework for high-rate and long-cycle-life lithium ion batteries

“…This interaction induces the formation of solid-electrolyte interface (SEI) layers that affect ionic conduction and electrode capacity. [41][42][43][44] Polymers in GPEs may form a complex with SEI layers to circumscribe further electrolyte decomposition on the anode.…”
