Abstract

L'invention concerne un matériau d'électrode positive monocristallin ternaire, un procédé de préparation et une utilisation de celui-ci. Le procédé de préparation comprend les étapes suivantes : mélanger une micropoudre polycristalline ternaire, augmenter la température, effectuer un frittage primaire et abaisser la température pour obtenir un intermédiaire ; soumettre l'intermédiaire à une pulvérisation par jet pour obtenir un matériau monocristallin, laver le matériau monocristallin avec de l'eau et sécher par centrifugation le matériau monocristallin pour obtenir un matériau avec une teneur résiduelle en alcalins inférieure à 1500 ppm ; et ajouter un agent de revêtement au matériau, augmenter la température, effectuer un frittage secondaire et abaisser la température pour obtenir le matériau d'électrode positive monocristallin ternaire. Dans la présente invention, en utilisant un dispositif de pulvérisation à jet pour ouvrir un matériau polycristallin afin de former de petites particules monocristallines, les performances électrochimiques du matériau sont améliorées et la densité énergétique du matériau est améliorée.
