Reduction of calcium corrosion in thionyl chloride-based electrolytes

Concern in respect of the safety of lithium oxyhalide cells has led to a search for alternative anode materials. A well-documented alternative is calcium; but this corrodes more rapidly than does lithium. This corrosion is a fundamental shortcoming of the calciumthionyl chloride system and must be...

Description
Summary:Concern in respect of the safety of lithium oxyhalide cells has led to a search for alternative anode materials. A well-documented alternative is calcium; but this corrodes more rapidly than does lithium. This corrosion is a fundamental shortcoming of the calciumthionyl chloride system and must be improved before exploitation is feasible. We have demonstrated that modification of the electrolyte can result in a considerable decrease in the calcium corrosion rate.
