    I’ve heard of these kinds of batteries before and it’d be cool to have long-running electronics, but would these produce enough power?

      They do, if you give them enough room. And if you are born into an oil family.

      The power density is about 0.01125m³ per watt. A high end smartphone (11w of peak power) with a body size similar to Galaxy s23 ultra, would be almost 10 meters thick.
