Despite its tiny size, the battery manages to achieve a 200-watt-hour-per-liter energy density, which is comparable to that of larger, conventional lithium-ion batteries.

    Sure, if your phone only needs a fraction of a watt and you’re okay with an unshielded neutron source pressed against your head.

      If the mars rovers can function on a fraction of a watt, then I don’t know why my phone can’t…

        If the mars rovers can function on a fraction of a watt,

        It doesn’t?

        Perseverance’s power system works essentially like a nuclear battery. …The power system will reliably produce about 110 watts …The MMRTG also charges two lithium-ion batteries, … Perseverance’s power demand can reach 900 watts during science activities.

          Yeah, see!

          An RTG could power my phone!

          Sigh, let me spell my point out for you…

          What I mean is that I can absolutely believe that a solid state battery could power the next gen smart watch, I doubt it will.

          Just as an RTG could power my phone, but I doubt that it will be powered by it.
