ELECTROACTIVE MATERIAL AND USE THEREOF

摘要

An electroactive material and a method of manufacturing the same is provided, in which the primary component of the electroactive material is a metal boron oxide complex, and the electroactive material exhibits excellent charge/discharge characteristics. The electroactive material of the present invention is primarily composed of an amorphous metal complex represented by the general formula M2-2X B2X O3. M is one or two or more metal elements selected from the transition metal elements, e.g., Fe or V. In addition, x is 0 < x < 1, e.g., 1/2. This type of electroactive material can be manufactured by amorphizing the metal complex represented by the general formula M2-2X B2X O3 by means of a mechanical milling method. In addition, the electroactive material can be manufactured by rapidly cooling and solidifying a mixture containing an oxide in which M is a constituent metal element and a boron oxide from the melted state.
