As recently noted by Ceder [73], little research has been done thus far on sodium alloy materials as negative electrodes for sodium-ion batteries, although silicon alloys are well-researched for Li-ion batteries. The electrochemical sodiation of lead has been reported and up to 3.75 Na per Pb were found to react [39].
