ABSTRACT:
An electrochemical cell, and a method of producing an electrochemical cell are provided. The method includes a step in which a counter electrode film and a mold film are crimped. A sol-gel precursor is inserted into a pore in the mold film provided on the counter electrode film. The sol-gel precursor is cooled to form a semi-hardened gel. The mold film is peeled off from the counter electrode film. The semi-hardened gel is cooled to form a gel electrolyte film. The sealing film is provided on the counter film, with the gel electrolyte film being fitted in the pore of the sealing film. A working electrode film is crimped on the sealing film. The stacked films are thermocompression bonded, and a single electrochemical cell is produced by cutting.
