An electrode component for an electrochemical cell is described wherein the electrode is produced by thermal spraying an electrode active material onto a substrate to coat the substrate. Suitable thermal spraying processes include chemical combustion spraying and electrical heating spraying, using both wire and power processes. La présente invention décrit un élément électrode pour batterie électrochimique dans laquelle on crée l'électrode sous forme d'un matériau actif thermiquement diffusé sur un substrat pour former un revêtement en couche sur ledit substrat. Les procédés de diffusion thermique comprennent une diffusion par combustion chimique et une diffusion par chauffage électrique au moyen des deux processus fil et énergie.
