Title (EN) LITHIUM PRIMARY CELLS
(FR) PILES PRIMAIRES AU LITHIUM
Abstract:
(EN) A method for treating a cathode electrode assembly. The method includes providing an electrode including iron disulfide and contacting the electrode with water to remove impurities from the electrode. The electrode may then be dried under various conditions. The moisture content of the electrode after drying may be less than about 600ppm.
(FR) L'invention concerne un procédé de traitement d'un assemblage cathode-électrode. Le procédé comprend l'obtention d'une électrode contenant du disulfure de fer et le contact de l'électrode avec de l'eau pour éliminer les impuretés de l'électrode. L'électrode peut ensuite être séchée selon diverses conditions. La teneur en humidité de l'électrode après séchage peut être inférieure à environ 600 ppm.
