Abstract: L'invention concerne un diaphragme et une batterie haute tension comprenant ce dernier. Une couche de modification est appliquée sur la surface d'une particule céramique inorganique de manière à adsorber des ions de métal de transition précipités à partir d'un matériau d'électrode, ce qui permet d'empêcher la formation de précipités de métal de transition sur une surface d'une électrode négative par les ions de métal de transition, et d'améliorer la sécurité, les performances de vitesse et les performances de cycle de la batterie. De plus, étant donné que la couche de modification est appliquée sur la surface de la particule céramique inorganique, la couche n'a pas d'impact significatif sur la résistance interne de la batterie, et ne réduit donc pas les performances de vitesse, les performances à basse température et les performances de cycle de la batterie. L'introduction d'un matériau de modification permet en outre l'adsorption d'une quantité à l'état de trace de HF produit dans le système de batterie, ce qui permet d'inhiber la dissolution des ions de métal de transition, de stabiliser la structure de surface d'une électrode positive, et d'améliorer les performances de la batterie, tout en réduisant la corrosion des matériaux d'emballage de batterie par le HF et en améliorant les performances de sécurité de la batterie.
