N2 - Ion‐conductive polymer which shows an ionic conductivity (σi) of 1.4 × 10−4S/cm at 25°C when mixed with LiClO4 (molar ratio in Li/OE = 0.05) was used as a separator of electrodes in a lithium secondary battery. The effect of high ionic conductivity on the performance of the battery was studied. The polymer structure was $$ \left[ {\rm H}\rlap{-} ({\rm CH}_2 {\rm CHR}\rlap{-} )_{\rm n} {\rm H},{\rm R} = - {\rm CH}_2 ({\rm OCH}_{\rm 2} {\rm CH}_{\rm 2} )_6 {\rm OCH}_3 \right],$$ and the cathode was comprised of poly(1,3,4‐thiadiazole disulfide), graphite powder and the polymer electrolyte. The cell [(−)Li/polymer electrolyte/graphite–poly(disulfide) (+)] had an open circuit voltage (Voc) of 3.25 V, a plateau voltage of 2.75 V, a discharge density (id) of 0.05 mA/cm2 with the cathode utilization of 63%, and achieved over several tens of cycles at 25°C.
