1. A method (400, 405) to manufacture a polymer electrolyte within an electrochemical device, the method comprising:
a. mixing a liquefied gas solvent, a salt, and a polymer to form a homogeneous mixture (405, 410, 425, 430);
b. inject the homogeneous mixture into the electrochemical device;
c. venting the liquified gas solvent from the homogeneous mixture (415, 435) out of the electrochemical device; and
d. forming a homogeneous polymer electrolyte (415, 435) within the electrochemical device.
