Abstract
- Polyacrylonitrile (PAN) based solid polymer electrolyte consisting lithium tetrafluoroborate (LiBF), ethylene carbonate (EC) and dimethyl phthalate (DMP) have been prepared using solution casting method. Comparative studies were done on unplasticized PAN-LiBF system and the PAN plasticized system with the novel binary plasticizers of EC and DMP in the ratio of 1:1 by the variation of LiBF concentration. The highest room temperature conductivity of electrolyte in PAN-LiBF system is 1.83 × 10 S cm while 1.08 × 10 S cm is obtained from PAN-EC-DMP-LiBF system. The complexation and structure of polymer electrolytes have been investigated as function of LiBF content at different weight percentages. The morphology and crystalline phase of polymer host is completely changed on the addition of salt and plasticizers. The fraction of free ions is greatly dependent on the amount of salt and the presence of plasticizers. [ABSTRACT FROM AUTHOR]
