Abstract | The present invention provides improved cathode material comprised of electrolytic manganese dioxide having high discharge capacity at high discharge rates and methods of producing such electrolytic manganese dioxide by electrolysis in an electrolytic cell. The methods are basically comprised of maintaining a heated high purity aqueous electrolyte solution comprising sulfuric acid and manganese sulfate in the electrolytic cell, the manganese sulfate being present in the solution whereby it contains in the range of from about 5 to about 50 grams of manganese per liter of solution. An electric current is applied to the electrodes of the electrolytic cell whereby the anodic electrode current density is in the range of from about 2.5 to about 6 amperes per square foot. A graphical representation of the experimental results shows that relative discharge energy decreases as the anodic electrode current density increases.
La présente invention concerne un matériau de cathode amélioré comprenant du dioxyde de manganèse électrolytique de capacité de décharge élevée, et concerne également les procédés de production par électrolyse d'un tel dioxyde de manganèse électrolytique dans une cellule électrolytique. Ces procédés consistent principalement à maintenir une solution électrolytique aqueuse chauffée de grande pureté contenant de l'acide sulfurique et du sulfate de manganèse dans la cellule électrolytique, le sulfate de manganèse étant présent dans la solution qui renferme entre environ 5 et environ 50 grammes de manganèse par litre de solution. Par ailleurs, on applique un courant électrique aux électrodes de la cellule électrolytique, la densité de courant anodique de l'électrode étant comprise entre environ 2,5 et environ 6 ampères/pied carré. Un représentation graphique des résultats d'expérience démontrent que l'énergie de décharge relative diminue lorsque la densité de courant anodique de l'électrode augmente. |
