Claim 18:
19. A method of creating a supercapacitive lithium-ion battery comprising the steps of:
a. providing an anode;
b. providing a cathode;
c. preparing a solid-state electrolyte polymer membrane comprising the steps of:
i. mixing a lithium salt, a plasticizer, and a co-network of a crosslinkable polyether addition and a crosslinkable amine addition; and
ii. crosslinking the mixture to form said solid-state electrolyte polymer membrane;

d. combining the anode, the cathode, and the solid-state electrolyte polymer membrane to create a lithium-ion battery; and
e. lithiating the lithium-ion battery by deep discharging the lithium-ion battery, wherein deep discharging includes lowering the voltage to −0.5 V and then increasing the voltage to 0.5 V during a first cycle of the lithium-ion battery so as to form a supercapacitive lithium-ion battery, wherein the supercapacitive lithium-ion battery has an operating range of between about 0.01 and about 4.3 V without short-circuiting.
