1. A composition of a nano-tube composite polymer electrolyte, comprising:

  • a polymer substrate having main-chains and side-chains, which at least have an ether group, an acyl group, an amino group, a fluoro group or a Lewis base functional group;

    a metal salt comprising a metal cation and an anion, wherein the metal salt and the polymer substrate form a polymer salt complex; and

    a nano-tube modifier forming Lewis acid-base force with the polymer substrate and the polymer salt complex, wherein the nano-tube modifier is TiO2, SiO2, or Al2O3 and has a diameter from about 50 nm to about 160 nm.
