Claim:
1. A fused product obtained by solidification by cooling of a molten material melted at a temperature greater than 1450° C., said fused product comprising lithium-manganese spinel, which is optionally doped, having a spinel structure AB 2 O 4 , where the site A is occupied by lithium and the site B is occupied by manganese, the site B being optionally doped with an element B′ and the site A exhibiting optionally a substoichiometry or a superstoichiometry with respect to the site B, so that the product observes the formula Li (1+x) Mn (2−y) B′ y O 4 , with −0.20≦x≦0.4 and 0≦y≦1, the element B′ being selected from the group consisting of aluminum, cobalt, nickel, chromium, iron, magnesium, titanium, vanadium, copper, zinc, gallium, calcium, niobium, yttrium, barium, silicon, boron, zirconium and mixtures thereof, the said fused product comprising a content of optionally doped lithium-manganese spinel of greater than 50%, impurities excluded, the optionally doped lithium-manganese spinel, named LMO, content, impurities excluded, in %, being defined as where A A
