Abstract
A non-aqueous battery has a positive electrode having a composition essentially represented by a formula LixNiOy (0<x<1.3 and 1.8<y<2.2), a negative electrode having a material which occludes and releases lithium reversibly and a non-aqueous electrolyte. The composition has a ratio of I.sub.104 to I.sub.003 ranging from 0.35 to 0.68 when measured by an X-ray powder diffraction method using CuK.sub..mu. as a target. The I.sub.104 represents a peak intensity of reflection of X-rays at an angle about 2.theta.=44 degrees with respect to the lattice plane (104), and the I.sub.003 representing another peak intensity of reflection of X-rays at an angle about 2.theta.=19 degrees with respect to the lattice plane (003).
