Room temperature rechargeable polymer electrolyte batteries

Polyacrylonitrile (PAN)- and poly(vinyl chloride) (PVC)-based Li+-conductive thin-film electrolytes have been found to be suitable in rechargeable Li and Li-ion cells. Li/LixMn2Oy and carbon/LiNiO2 cells fabricated with these electrolytes have demonstrated rate capabilities greater than the C-rate and more than 375 full depth cycles. Two-cell carbon/LiNiO2 bipolar batteries could be discharged at pulse currents as high as 50 mA/cm2.
