In the present work, various non-equilibrium processing techniques have been attempted to increase the ionic conductivity of PEO-LiClO4 solid electrolytes: high-energy ball milling, rapid quenching and the addtion of multi-wall nanotubes to the PEO-LiClO4 electrolytes. Both high-energy ball milling and rapid quenching increased the ionic conductivity by promoting amorphization. The addition of uniformly dispersed carbon nanotubes to the PEO-LiClO4 also influences the crystalline kinetics of the PEO-LiClO4, thereby improving markedly ionic conductivity. This improved conductivity is attributed to an enhanced amorphization by a local change of PEO chains from crystalline to disordered arrangement.
