Study of all-solid state lithium/polyacenic semiconductor (PAS) battery

Some new polymer electrolytes, polyacrylonitrile-based lithium salt complexes, with high conductivity at ambient temperature have been developed. The electrical conductivity measurement, XRD and NMR results have been given. Solid-state lithium/polyacenic semiconductor (PAS) batteries using these polymer electrolytes have been constructed and tested. The charge and discharge behaviour has been studied, recycleability and the rate of self-discharge were measured at room temperature. When a battery cycled between 4.0 and 2.0 V, after 125 cycles the battery still has 97% capacity of the 10th cycle. The specific capacity was up to 58.6 mAh/g (based on the weight of PAS).
