Some new polymer electrolytes, polyacrylonitrile-based lithium salt co
mplexes, with high conductivity at ambient temperature have been devel
oped. The electrical conductivity measurement, XRD and NMR results hav
e been given. Solid-state lithium/polyacenic semiconductor (PAS) batte
ries 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).
