Patent ID: 7282299

Claim:
A solid electrolyte battery comprising: a cathode including a cathode composite mixture, said mixture comprising a cathode active material and a solid electrolyte wherein said solid electrolyte comprises a first polymer and a second polymer; an anode; and a separator disposed between said cathode and said anode; wherein said first polymer has a binding force; and wherein said first polymer is selected from the group consisting of polyvinylidene fluoride, polytetrafluoro ethylene, styrene-butadiene rubber, and mixtures thereof; and wherein said second polymer is capable of conducting alkali-metal ions and comprises an electrolyte salt and a complex; and comprising one or more repeating structural units of formula II, wherein n is an integer from 1 to 12; and wherein R 1 is selected from the group consisting of alkyl groups having 1 to 12 carbons, alkenyl groups having 2 to 8 carbons, cycloalkyl groups having 3 to 8 carbons, aryl groups having 6 to 14 carbons, aralkyl groups having 7 to 12 carbons, and tetrahydropyranyl groups.
