摘要

A novel polymer matrix with a polar carbonyl group was designed and used to prepare an all-solid polymer electrolyte in lithium rechargeable batteries. The ionic conductivity of this type of polymer electrolyte was examined. The relationship between the lithium salt concentration and ionic conductivity was investigated by Fourier transform infrared (FTIR) spectroscopy. The carbonyl groups in the polymer matrix effectively interacted with the lithium salt, which improved the ionic conductivity at a large range of temperatures. The ionic conductivity of this type of polymer electrolyte was approximately 10~(-4) S cm~(-1) at room temperature. The stability of the interface between electrode and electrolyte was evaluated by measuring the alternating current (AC) impedance.
