Lithium-Ion Secondary Battery and Storage Device

When a short circuit occurs in a lithium-ion secondary battery, a short circuit current is reduced to suppress temperature rise of the battery. In order to solve the above problem, a lithium-ion battery of the present invention includes an electrode having a mixture layer and a heat resistant layer...

Beschreibung
Zusammenfassung:	When a short circuit occurs in a lithium-ion secondary battery, a short circuit current is reduced to suppress temperature rise of the battery. In order to solve the above problem, a lithium-ion battery of the present invention includes an electrode having a mixture layer and a heat resistant layer disposed on the mixture layer and containing ceramic particles. The heat resistant layer includes a crosslinked resin, and the amount of the crosslinked resin is less than 10% by weight with respect to the sum of the amount of the ceramic particles and the amount of the crosslinked resin.
