Abstract Poly(vinyl alcohol) (PVA) forms transparent homogeneous composites with lithium salt (LiClO4, LiBF4, and LiCF3SO3) up to 50–60 wt-% of the lithium salt in the composites. The composites show electrical conductivity of 10−6 − 2 × 10−4 S cm−1 at 50 wt-% of the lithium salt at 20 °C. Temperature dependence of the electrical conductivity obeys Arrehnius type equation in most cases with activation energies of 50–107 kJ mol−1
