The present invention is directed to novel block copolymers and to novel polymeric electrolyte compositions, such as solid polymer electrolytes that comprises a block copolymer including a first block having a glass transition temperature greater than about 60° C. or a melting temperature greater than about 60° C., and a second block including a polyalkoxide. The polymer electrolyte composition preferably has a shear modulus, G′, measured at 1 rad/sec and about 30° C. and a conductivity, &sgr;, measured at about 30° C., such that i) G′—&sgr; is greater than about 200 (S/cm)(dynes/cm2); and ii) G′ is from about 104 to about 1010 dynes/cm2. |
