Electrochemical cell, having a positive electrode comprising electrolytic manganese dioxide, chemical manganese dioxide, lithiated manganates, cobaltates or nickelates as electroactive component and graphite as a conductive additive, which is characterized 1. Electrochemical cell having a positive electrode comprising electrolytic manganese dioxide, chemical manganese dioxide, lithiated manganates, cobaltates or nickelates as electroactive component and graphite as a conductive additive, characterized in that said conductive additive comprises at least a thermally expanded graphite in its vermicular form, and wherein the initial graphite particle expansion degree of said expanded graphite in z-direction of the particle is greater than 80 times of its initial z-dimension, and preferably within the range of 200 to 500 times of its initial z-dimension.

Cette pile électrochimique comporte une électrode positive contenant du dioxyde de manganèse électrolytique, du dioxyde de manganèse chimique, des manganates, des cobaltates ou des nickelates lithiés comme adjuvants de conductivité, tel que caractérisés en (1). L'invention concerne également une pile électrochimique possédant une électrode positive contenant du dioxyde de manganèse électrolytique, du dioxyde de manganèse chimique, des manganates, des cobaltates ou des nickelates lithiés comme composants électro-actifs et du graphite comme adjuvant de conductivité, lequel se caractérise par le fait qu'il renferme au moins du graphite expansé par voie thermique sous sa forme vermiculaire. Le degré d'expansion de la particule initiale de graphite dans le sens Z de la particule est supérieur à 80 fois sa dimension Z initiale et est compris, de préférence, entre 200 et 500 fois cette dimension Z initiale.
