Gel electrolyte for secondary battery, secondary battery, and method for producing gel electrolyte for secondary battery

摘要

PPROBLEM TO BE SOLVED: To achieve the conductivity and mechanical strength of a gel electrolyte at the same time. PSOLUTION: Two gel electrolytes with high conductivity and high ratio of the included electrolytic solution are manufactured (S10), and at the same time, a gel electrolyte with high mechanical strength and low ratio of the included electrolytic solution is manufactured (S12). After that, both gel electrolytes are pasted one after another (S14), and the gel electrolyte is completed. As a result, as the electrolytic solution in the gel electrolyte is moved from the electrolyte with the high ratio of the included electrolytic solution to the electrolyte with the low ratio of included electrolytic solution, the conductivity of the gel electrolyte can be high on the whole, and at the same time, a sufficient mechanical strength can be maintained on the whole by the gel electrolyte with high strength.
