Thin lithium cobalt dioxide rechargeable cells using polyacrylonitrile-based polymer electrolytes. Technical report
Rechargeable Li/LiCoO2 cells with polymer electrolytes have achieved 100 mAh/g capacity and over 75 charge/discharge cycles with an average discharge potential of 3.7 volts. Solid-state polymer lithium electrolytes based on poly(acrylonitrile) (PAN) have achieved room temperature conductivities of 0,001 siemens per cm, equal to that of some liquid organic electrolytes. Polymer films of ethylene carbonate, propylene carbonate, PAN, and lithium salts have yielded conductivities as high as 4x10-4 siemens per cm at 25 deg C. These high conductivities made the use of polymer electrolytes a viable possibility in advanced lithium batteries. Reported here are the film preparation techniques, conductivities from -70 to 70 deg C, and discharge curves of Li/LiCoO2 cells.
