Abstract
A method for producing water resistant cathodes is discussed. The method uses mixing cathode powder with solid carbon dioxide to create a mixture and heating the mixture to a temperature. The heating occurs for a time sufficient to cause lithium carbonate coatings to form on the powder. A method for coating lithium-containing cathode surfaces is also discussed. This method uses simultaneously sublimating solid COand condensing atmospheric water vapor onto surfaces. Afterwards allowing the lithium to react with the sublimated COfor a time sufficient to create a lithium carbonate film on the surface.
