Abstract:
A method of making a composite solid polymer electrolyte comprised of a mobile charge-carrying species in a nano-composite material formed by the condensation of a ceramic precursor in the presence of a polymer, the method comprising:providing a mixture of solvated polymer and ceramic precursor; adding a condensation-agent, comprising a cation selected from the group consisting of Li+, Na+, and Mg+ and an OHâˆ’ anion associated with the cation, to the mixture so that condensation of the ceramic precursor takes place to form the nano-composite material; forming the nano-composite material into a membrane; and drying the membrane; wherein said cation is mobile within the nano-composite material to be the mobile charge-carrying species.
