Abstract:
Provided are an aqueous electrolyte composition including hydrophilic microparticles and a sealed-type primary film battery including an electrolyte layer formed of the aqueous electrolyte composition. In the sealed-type primary film battery, a separation film is interposed between a positive electrode and a negative electrode, and has a plurality of through-holes. A non-flowable electrolyte layer interposed between the positive electrode and the negative electrode includes first and second electrolyte layers extending parallel to the positive electrode and the negative electrode, and a plurality of third electrolyte layers filled in the through-holes of the separation film so as to be integrally connected to the first electrolyte layer and the second electrolyte layer. Due to the third electrolyte layers filled in the through-holes of the separation film, an ion transfer path in the electrolyte layer is shortened. The hydrophilic microparticles are dispersed in the electrolyte layer so as to prevent moisture evaporation.
