Abstract
The invention provides nickel hydroxide secondary particles comprising agglomerates of primary particles of nickel hydroxide in the shape of a triangular prism or a triangular plate having a surface or a outer face in the form of a substantially equilateral triangle each side of which substantially equilateral triangle has a length of 1 to 10 .mu.m. The invention further provides lithium nickel composite oxide secondary particles comprised of agglomerates of primary particles having a large particle diameter by mixing the nickel hydroxide secondary particles with a lithium compound and sintering the resulting mixture at a temperature of 600.degree. C. to 1000.degree. C. in an oxidative atmosphere.
