ABSTRACT:
An amorphous ionically conductive macromolecular solid is set forth having improved ambient temperature ionic conductivity. The solid comprises a solid solution of at least one positively charged ionic species dissolved in a macromolecular material, the macromolecular material comprising a polymer or copolymer having a polyether structure and having at least a portion of the ether oxygens thereof replaced with S or NR wherein R includes at least one basic site capable of associating with the positively charged ionic species and has 2 to 10 carbon atoms. Relatively high conductivity is a feature of the macromolecular solid of the invention.
