1. A method for manufacturing an electronic device, comprising the steps of:
preparing a power storage device comprising:
a positive electrode;
a negative electrode comprising graphite;
an exterior body surrounding the positive electrode and the negative electrode; and
an electrolyte included in a space surrounded by the exterior body, the electrolyte comprising a solvent component and lithium bis(pentafluoroethanesulfonyl)amide;
setting the power storage device in a mold;
pouring a rubber material in the mold after setting the power storage device; and
performing a heat treatment on the rubber material at a temperature higher than or equal to 110° C. and lower than or equal to 190° C. in the mold to cure the rubber material,
wherein the solvent component comprises propylene carbonate and ethylene carbonate,
wherein the propylene carbonate is the highest proportion in the solvent component except the ethylene carbonate, and
wherein the exterior body comprises a laminate film.
