Abstract 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 6O°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, s, measured at about 30 °C, such that i) G'- s is greater than about 200 (S/cm)(dynes/cm2); and ii) G' is from about 104 to about 1010 dynes/cm2. La présente invention porte sur de nouveaux copolymères à blocs et sur de nouvelles compositions d'électrolytes polymères, tels que des électrolytes polymères solides qui comportent un copolymère à blocs comprenant un premier bloc ayant une température de transition vitreuse supérieure à environ 60°C ou une température de fusion supérieure à environ 60°C, et un second bloc comprenant un polyalcoxyde. La composition d'électrolytes polymères possède de préférence un module de cisaillement, G', mesuré à 1 rad/s et à environ 30°C et une conductivité, s, mesurée à environ 30°C, tels que i) G'-s est supérieur à environ 200 (S/cm) (dynes/cm²), et ii) G' est d'environ 104 à environ 1010 dynes/cm².
