Title:
SEMISOLID ELECTROLYTE, ELECTRODE, ELECTRODE HAVING SEMISOLID ELECTROLYTE LAYER, AND SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2018/230238
Kind Code:
A1
Abstract:
The purpose of the present invention is to prolong the life of a secondary battery. This semisolid electrolyte includes: a semisolid electrolytic solution that includes a semisolid electrolytic solvent and a negative electrode interface additive; and particles, wherein the weight ratio of the negative electrode interface additive with respect to the sum of the weight of the semisolid electrolyte and the weight of a negative electrode to be applied is 0.6-11.7%. The weight ratio of the negative electrode interface additive to be applied with respect to the sum of the weight of the semisolid electrolyte and the weight of the negative electrode is preferably 1.7-5.8% by weight. In the secondary battery which includes the semisolid electrolyte, the capacity maintenance rate of the secondary battery after a prescribed number of cycles is preferably higher than that of a secondary battery not including the negative electrode interface additive.
