The effect of semi-IPN structure on gel-type polymer electrolyte
Thermal stability of PVdF Gel polymer electrolyte (GPE) was enhanced by crosslinking with PEGDA. The resulting semi-IPN structure reduced the crystallization of PVdF and had better affinity with organic liquid electrolyte. When the cell composed of LiCoO2/GPE/Li foil was tested at 80 degreesC, interfacial impedance results indicated the higher thermal stability of GPE than PVdf.
