NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

WIPO Patent Application WO/2015/079629

A1

This nonaqueous electrolyte secondary battery is provided with: a positive electrode that contains, as a positive electrode active material, a lithium-nickel composite oxide containing at least Ni at a ratio of 80% by mole or more relative to the total molar quantity of metal elements excluding Li; and a negative electrode that contains, as a negative electrode active material, lithium titanate. The electrical capacity (A) of the positive electrode and the electrical capacity (B) of the negative electrode satisfy the relation 1.05 ≤ (B)/(A) ≤ 1.20. This nonaqueous electrolyte secondary battery is able to achieve high electrical capacity both during low-temperature charge and during high-rate discharge.
