Abstract

The invention provides a manganese dioxide-based material which is highly crystalline and chemically prepared. The material has a predominantly ramsdellite structure, and has a powder X-ray diffraction pattern (CuK.sub..alpha. radiation) in which the ratio of a [110] peak height to a [201] peak height is at least 0,6:1,0. The material can be used as an electrode material in an electrochemical cell 10.
