China has had production EVs with sodium ion batteries for 2 years. I wonder when scientists will invent Freedom sodium so I can buy one in America.

    China has had production EVs with sodium ion batteries for 2 years.

    CATL and Changan announced earlier this year that they'd be releasing the first mass produced EV with sodium ion batteries in mid 2026, and that sodium ion model still hasn't launched yet. What other vehicle are you saying beat them to this?

    Sodium cells last about half as many cycles as lithium. Poor choice for a car.

    Sodium cells also cost half as much to produce. Better cold-weather performance and charging to 80% in 15 minutes seem to tip the scale in their favor in many people's minds. Not to mention sodium being much more abundant and available than lithium. Categorically saying they're a poor choice for a car disagrees with multiple car companies - you must know more than they do.
