Abstract

An electro-active material, including a mixture of a first component including at least a first compound of formula (I) LiMnOand a second component including at least a second compound of formula (II) LiHVO, wherein in formula (I): 0≤x≤2, 1≤y≤3, and 2≤2y−x≤5, and wherein in formula (II): 0≤x≤4.5, 0.01≤y≤2, and 0.01≤x+y≤6.5. The first compound is in the form of particles having a certain particle size and the second compound is in the form of nanoparticles having a certain particle size or nanofibers having certain dimensions. The first and second components are present in amounts of 1:99% to 99:1% by weight, and the mixture, upon being mechanically pressed in a range of 20 to 70 KN with a die, has a synergic effect of pressed density (SEPD) greater than 100%.
