Abstract

L'invention concerne un procédé de préparation de phosphate de fer-lithium par recyclage de batteries usagées. Tout d'abord, des batteries usagées au phosphate de fer-lithium sont prétraitées pour obtenir des déchets purs de phosphate de fer-lithium ; ensuite, chaque élément est complété selon un rapport ; et un produit de phosphate de fer-lithium est préparé au moyen d'une pyrolyse par pulvérisation. Les gouttelettes de phosphate de fer-lithium pulvérisées par pyrolyse par pulvérisation présentent une sphéricité élevée et une distribution uniforme des grosseurs de particule. Après une réaction à haute température, du phosphate de fer-lithium sphérique est obtenu. La sphéroïdisation du phosphate de fer-lithium est bénéfique pour augmenter l'aire de surface spécifique du matériau et pour augmenter l'énergie volumique spécifique du matériau. Lors de l'élimination des impuretés, la chaleur perdue de phosphate de fer-lithium à haute température produite par pulvérisation est utilisée pour atomiser de l'eau pure pour éliminer les impuretés par pulvérisation, de telle sorte que l'eau pure atomisée est instantanément évaporée, éliminant ainsi les impuretés telles que le chlorure d'hydrogène dans les particules de phosphate de fer-lithium. Le matériau cathodique de phosphate de fer-lithium préparé présente quasiment la même capacité et la même performance de charge-décharge que le premier matériau cathodique de phosphate de fer-lithium synthétisé.
