I'm excited by sodium ion batts, especially in the 18650 format. Everyone's aware the danger of lithium ion with this format - lots of burns, fires and a death[1] caused by the cap of a flashlight being propelled into the throat of the user while holding it in his mouth during auto work. Stab a lithium 18650 and watch out! Water makes it worse. Stab a sodium 18650 and it wants to boogy for sure, but sans flames. While sodiums can't yet compete with liths, I think they'll get close enough for the safety benefit and cost to make them viable. And there will be new tech too.
