Abstract
Composite polymer electrolyte (PE) films comprising thermoplastic polyurethane (TPU) and polyacrylonitrile (PAN) (denoted as TPU-PAN) were prepared by two different processes. The preparation of the TPU-PAN gel PE was more convenient than the traditional way of making PAN based electrolyte. The TPU-PAN composite possessed good mechanical properties. The TPU-PAN based gel PE showed high conductivity at room temperature. The existence of PAN in the composite improved the thermal stability. The lithium plating-stripping process was a reversible and implied better electrochemical stability in the working voltage range. The Li/PE (TPU-PAN)/LiCoO2 cell was successfully constructed and the performance was assessed. The formation of passive layer at Li/PE interface influenced the charge-discharge characteristics.
