摘要： The present invention is directed to providing a lithium carbonate passivation layer on lithium through exposure of the active material to gaseous carbon dioxide prior to cell assembly. This results in an electrochemical cell which possesses improved safety and voltage delay characteristics in comparison to prior art cells comprising unexposed lithium. The preferred cell is of a lithium oxyhalide chemistry.

摘要： An electrochemical cell, and an associated process, wherein the cell includes a controlled electrode surface comprising an electrode with a carbonaceous surface, an electrolyte and a reduced additive. The reduced additive is formulated from an additive which is either soluble or insoluble in the solvated electrolyte prior to reduction. The invention further includes a passivating layer at the carbonaceous electrode/electrolyte interface. The passivating layer includes the additive and/or the reduced additive. This passivating layer substantially precludes contact between electrolyte solvent and the carbonaceous surface of the electrode to, in turn, substantially prevent gas formation within the cell, which would otherwise result from decomposition of the solvent upon contact with the carbonaceous surface. Also, the additive and/or the reduced additive will likewise be substantially precluded from generating a gas upon its decomposition.
