JAC Motors, a Volkswagen-backed Chinese automaker, unveiled the first mass-produced EV with a sodium-ion battery through its new Yiwei brand. Although sodium-ion battery tech has a lower density than lithium-ion, its lower costs, simpler and more abundant supplies and superior cold-weather performance could help accelerate mass EV adoption.

      For EVs, these batteries are better for the environment to produce and to dispose of, and if you’re able to replace them every time you go to a recharge station you’ll never have a battery die because it won’t be in your car long enough. The batteries keep rotating until they die and then they get taken out of rotation and disposed of.

        bit of a problem here:

        if batteries are kept in rotation until they die… you’ll most likely experience one dying on you. probably multiple times during your life.

        the rest holds up just…how would you avoid a battery dying on you, if you’re still using the same system? you’re not getting a new battery every time you swap, you get an old battery that’s been sitting in the station recharging.

        it’s gonna die on someone, might as well happen to you…

          There are ways to calculate a batteries remaining life, usually you’d have a chip dedicated to tracking all of that. They can tell you a battery’s history, health, estimated charge capacity etc. So if the station detects a batteries life is low or it’s marked as chaged but it’s charged significantly below it’s initial capacity it can be taken out of rotation and inspected and fixed/disposed of if need be.

          Personally I wonder, once we have interchangeable batteries, if it will be more common to have several smaller, shorter life span batteries that add up to a certain range. That way the recharge station only has to change out the batteries with a lower charge, and even if the battery system trips up and you get a borked battery your range would be slightly reduced not completely gone or halved
