Abstract

L'invention concerne une électrode positive de batterie au lithium-ion et son procédé de préparation, et un procédé de préparation d'une batterie au lithium-ion, l'électrode positive de batterie au lithium-ion comprenant un matériau d'électrode positive, du PVDF, un agent conducteur et du STOBA, les parties en masse du matériau d'électrode positive, du PVDF, de l'agent conducteur et du STOBA étant respectivement de 95 à 98 parties, de 0,5 à 0,9 partie, de 0,8 à 1,2 parties et de 0,2 à 0,5 partie ; le matériau d'électrode positive étant du manganate de lithium-nickel-cobalt, du phosphate de fer-lithium, du manganate de lithium, du phosphate de lithium-vanadium et/ou des matériaux ternaires de nickel-cobalt-aluminium. Une batterie au lithium-ion préparée en utilisant l'électrode positive présente les avantages de bonnes performances de cycle à haute température, d'une faible résistance interne et d'une faible auto-décharge, et résout les problèmes techniques d'une faible durée de vie en cyclage et d'une résistance interne élevée des batteries au lithium-ion dans des environnements à haute température dans l'état de la technique.
