Title:
LITHIUM-NICKEL COMPOSITE OXIDE AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/043302
Kind Code:
A1
Abstract:
A lithium-nickel composite oxide represented by general formula (1). (1) LixNiO2+δ [In the formula, x represents 0.8 ≤ x ≤ 1.3, and δ represents -0.20 ≤ δ ≤ 0.20.] The lithium-nickel composite oxide contains a crystal phase having a hexagonal layered rock salt structure, and has a lattice constant c of not less than 14.130 Å but less than 14.190 Å, and has a high capacitance and enables significant suppression of deterioration in cycle characteristics.
