Abstract:
1. A method of producing an electrochemical cell, said method comprising: a step of inserting a sol-gel precursor into a pore in a mold film provided on a counter electrode film having a thickness of 50 to 500 μm, the pore in the mold film having a length of 5 to 500 mm and a width of 5 to 500 mm; a step of cooling the sol-gel precursor to form a semi-hardened gel having predetermined viscosity of 20 to 20,000 mPas; a step of peeling the mold film off from the counter electrode film; a step of cooling the semi-hardened gel to form a gel electrolyte film having a thickness of 30 to 500 μm; a step of providing a sealing film on the counter electrode film, with the gel electrolyte film being fitted in a pore of the sealing film; and a step of providing a working electrode film on the sealing film and the gel electrolyte film, with thermocompression bonding.
