Title (EN) SULFATE ELECTRODES
(FR) ÉLECTRODES DE SULFATE
Abstract:
(EN) The invention relates to electrodes that contain active materials of the formula: Aa Mb(SO4)cXx wherein A is a single or mixed alkali metal phase comprising one or more of sodium, potassium, lithium mixed with sodium, lithium mixed with potassium or lithium mixed with sodium and potassium; M is selected from one or more transition metals and/or non-transition metals and/or metalloids; X is a moiety comprising one or more atoms selected from halogen and OH; and further wherein 1 < a < 3; b is in the range: 0 < b ≤ 2; c is in the range: 2 ≤ c ≤ 3 and x is in the range 0 ≤x ≤ 1. Such electrodes are useful in, for example, sodium ion battery applications.
(FR) L'invention concerne des électrodes qui contiennent des matériaux actifs de la formule : Aa Mb(SO4)cXx dans laquelle A représente une phase de métal alcalin simple ou mixte comprenant un ou plusieurs parmi le sodium, le potassium, le lithium mélangé au sodium, le lithium mélangé au potassium ou le lithium mélangé au sodium et au potassium ; M est sélectionné parmi un ou plusieurs métaux de transition et/ou métaux de non transition et/ou métalloïdes ; X représente un fragment comprenant un ou plusieurs atomes choisis parmi l'halogène et l'OH. De plus dans la formule, 1 < a < 3 ; b est dans la plage : 0 < b ≤ 2 ; c est dans la plage : 2 ≤ c ≤ 3 et x est dans la plage 0 ≤ x ≤ 1. De telles électrodes sont utiles dans, par exemple, des batteries à ions de sodium.
