Abstract: The preparation of 2,6‐Bis(m‐amino phenoxy) benzoyl naphthalene‐based polyimides for solid polymer electrolytes was reported. Li‐salt and PEO bearing polyimide membranes were prepared. Thermo‐gravimetric analysis results reveal that the PI/PEO/LiCF3SO3 polymer electrolyte membranes are thermally stable up to 500°C. The “Tg” values are in the range 167–221.5°C according to dynamic mechanical analysis (DMA). The conductivities of Li‐salt and PEO containing PI membranes are in the range of 10−7–10−5 S/cm. The conductivity increases with incorporation of PEO and Li+ concentration. The linear sweep voltammetry experiments showed that no peaks were observed between 1.75 and 4.5 V.
