摘要：

The Na/PVdF/S cells were composed of solid sodium, sulfur, and polyvinylidene fluoride-hexafluoropropene (PVdF) gel polymer electrolyte. The PVdF polymer electrolyte was prepared form tetraglyme plasticizer and NaCF3SO3 salt, and its electrochemical properties were studied using CV and impedance analysis. The interfacial resistance between sodium and polymer electrolyte increase with storage time, which might be associated with passivation layer. Solid-state sodium/sulfur cell using a PVdF gel polymer electrolyte has been tested. The Na/PVdF/S cell with 0.288 mA cm(-2) stop shows a high discharge capacity of 392 mAh g(-1) stop and 36 mAh g(-1) stop after 20 cycles. The cycle performance of Na/GPE/S cell operating at 25 degrees C is worse than Na/S cell at a high temperature.
