An electrochemically active material comprising a mixture or blend of two groups of particles, exhibits synergetic effect. The two groups of particles are compounds of formula Li x H y V 3 O 8 and compounds of formula Li x M y (AO z ) v O w wherein M is one or more transition metals, comprising at least one metal which is capable of undergoing oxidation to a higher valence state, and preferred (AO z ) are PO 4 3- , BO 3 3- , SO 4 2- or SiO 4 4- . In order to obtain a synergistic effect, the particles of formula (I) and the particles of formule (II) are present in amounts of 5 :95 % by weight to 95 : 5 % by weight. |
