Electrode and gel electrolyte cell production method

A method for producing a gel electrolyte cell, the method comprising the steps of:

• forming an electrode including a rectangular electrode carrier and a gel electrolyte film formed on the electrode carrier and having a width greater than the electrode carrier by:
• overlaying a first carrier having a greater width than the gel electrolyte film, a second carrier having a width approximately identical to that of the gel electrolyte film, and the electrode carrier in this order,
• applying an electrolyte composition onto the first carrier, the second carrier, and the electrode carrier which have been overlaid upon one another, in such a manner that the applied electrolyte composition has a width greater than the width of the second carrier and smaller than the width of the first carrier,
• peeling off, from the first carrier, the second carrier and the electrode carrier coated with the applied electrolyte composition,
• forming into the gel electrolyte film the electrolyte composition applied onto the second carrier and the electrode carrier which have been peeled off from the first carrier, and
• peeling off from the second carrier the electrode carrier and the gel electrolyte film formed of the electrolyte composition;
• and
• producing the gel electrolyte cell including the formed electrode,
• wherein the electrolyte composition is applied in a sol state,
• wherein the electrolyte composition contains an electrolyte salt, a matrix polymer, and a swelling solvent, and
• wherein the matrix polymer is further defined as being selected from the group consisting of polyhexafluoropropylene, polypropylene oxide, polyphosphazene, polysiloxane, polyacrylic acid, polymethacrylic acid, styrene-butadiene rubber, nitrile-butadiene rubber, and polycarbonate.
