Title:
NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2021/039178
Kind Code:
A1
Abstract:
The present invention is a non-aqueous electrolyte secondary battery having: a positive electrode; a separator; a negative electrode opposed to the positive electrode with the separator interposed therebetween; and an electrolytic solution. The positive electrode contains a composite oxide containing lithium serving as a first metal and a second metal other than lithium. In the composite oxide, the second metal contains Ni, where Ni accounts for 90 atomic% or more in the second metal, and Co accounts for 10 atomic% or less in the second metal. The electrolytic solution contains at least one cation X selected from the group consisting of Na+, K+, Rb+, Cs+, Fr+, Mg2+, Ca2+, Sr2+, Ba2+, and Al3+ and an oxalate complex anion Y.
