Open the CIPO recordAbstract From the Canadian patent
Calcium alloys such as calcium-aluminum and calciumsilicon, are employed as active material within a rechargeable negative electrode of an electrochemical cell. Such cells can use a molten salt electrolyte including calcium ions and a positive electrode having sulfur sulfides, or oxides, as active material. The calcium alloy is selected to prevent formation of molten calcium alloys resulting from reaction with the selected molten electrolytic salt at the cell operating temperatures.
