Abstract
According to the process of this invention, first a manganese oxide seed is prepared, which is then grown to obtain manganese oxide having large particle diameters. The manganese oxide thus obtained is reacted with a lithium compound, whereby lithium manganate having large particle diameters can be obtained. Since the lithium manganate has large particle diameters and gives a high packing density, lithium batteries with a high energy density can be provided by using the lithium manganate.
