The invention relates to a cathode material for a rechargeable electrochemical cell, said cell also comprising an anode and an electrolyte, the cathode material comprising a rhombohedral NASICON material having the formula Y x M2(PO4)y(XO4)3-y, where 0 < y < 3, M is a transition-metal atom, 0 <= x <= 5, Y is Li or Na, and X = Si, As, or S. The invention also relates to a secondary battery comprising an anode, a cathode and an electrolyte, the cathode being the cathode material described above.
Cette invention traite d'un matériau cathodique pour une pile électrochimique rechargeable qui comprend aussi une anode et un électrolyte. Le matériau cathodique est constitué de NASICON rhomboédrique de formule : Y x M2(PO4)y(XO4)3-y, où 0 < y < 3, M est un atome de métal de transition, 0 <= x <= 5, Y est du Il ou du Na, et X = Si, As ou S. Cette invention se rapporte également à une batterie rechargeable qui comprend une anode, une cathode et un électrolyte, la cathode étant le matériau cathodique décrit plus haut.
