Title:
LITHIUM-ION SECONDARY BATTERY, ELECTRICITY STORAGE DEVICE PROVIDED WITH SAME, NEGATIVE ELECTRODE MATERIAL SLURRY FOR LITHIUM-ION SECONDARY BATTERIES, AND NEGATIVE ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2015/104830
Kind Code:
A1
Abstract:
This lithium-ion secondary battery is provided with a negative electrode that contains an oxygen-containing polymer compound and a negative electrode active material which forms an alloy or compound with lithium. The oxygen-containing polymer compound is a mixture of a plurality of predetermined polymers. It is thus possible to provide a lithium-ion secondary battery which has a large initial capacity and has a small decline in the amount of lithium occluded by the negative electrode active material due to repeated charging and discharging.
