| description | The invention relates to niobium metal oxides, niobium metal oxide secondary particles and a process for preparing the same, as well as working electrodes and electrochemical cells comprising the niobium metal oxide secondary particles. The niobium metal oxide is of formula (I): NbxMyOz, wherein M is a metal selected from Ti, Zr, V, Cr, W and Mo, x is from 2 to 18, z is 2.5x+3y and x/y is from 1 to 3, and the crystal structure of the niobium metal oxide is a tetragonal tungsten bronze structure having four or eight pentagonal channels per unit cell, and a portion of the pentagonal channels are filled with -Nb-O-Nb-O- strings, and the remaining portion of the pentagonal channels are optionally intercalated with lithium.
L'invention concerne des oxydes métalliques de niobium, des particules secondaires d'oxyde métallique de niobium et leur procédé de préparation, ainsi que des électrodes de travail et des cellules électrochimiques comprenant les particules secondaires d'oxyde métallique de niobium. L'oxyde métallique de niobium est de formule (I) : NbxMyOz, M étant un métal choisi parmi Ti, Zr, V, Cr, W et Mo, x étant de 2 à 18, z étant 2,5x+3y et x/y étant de 1 à 3, et la structure cristalline de l'oxyde métallique de niobium est une structure de bronze de tungstène tétragonale ayant quatre ou huit canaux pentagonaux par cellule unitaire, et une partie des canaux pentagonaux est remplie avec des chaînes -Nb-O-Nb-O-, et la partie restante des canaux pentagonaux est facultativement intercalée avec du lithium. |
