Title (EN) ELECTROCHEMICAL CELL HAVING A PARTIALLY OXIDIZED CONDUCTOR
(FR) CELLULE ELECTROCHIMIQUE A CONDUCTEUR PARTIELLEMENT OXYDE
Abstract: front page image
(EN)An electrochemical cell having an aqueous electrolyte and an electrode with partially oxidized graphite mixed with an electrochemically active material. The graphite is oxidized on its surface and within a specified range of surface oxidation to improve the aqueous electrolyte's ability to diffuse into the electrode. The weight ratio of active material to graphite is maximized to improve performance on high drains tests.
(FR)Cette cellule électrochimique présente un électrolyte aqueux et une électrode à graphite partiellement oxydé mélangé à une matière électrochimiquement active. Le graphite est oxydé sur sa surface selon un taux spécifié afin d'améliorer la capacité aqueuse de l'électrolyte à se diffuser dans l'électrode. Le rapport pondéral de la matière active et du graphite est maximisé afin d'améliorer les performances sur des tests à drains élevés.
