Sodium-ion batteries have been in the works for years, and now sodium-ion batteries have started to appear in cars and home storage.

" CATL has thrown its hat into the ring with the Naxtra sodium-ion battery, with 175 Wh/kg and 10,000 lifetime cycles along with operation from -40°C to 70°C. CATL is planning a start-stop battery for trucks using the technology. It has the potential to replace lead-acid batteries. CATL has announced battery pricing at the cell level in volume at $19/kWh.

    I don’t see this as a valid comparison.

    • replacement phone batteries are really not that expensive. Don’t overthink it. Is it really a problem you might spend $50-$100 in three years to replace the battery?
    • car batteries are not just much more expensive but they’re also overkill. Charging to 80% is more than enough for almost everyone’s daily driving on most vehicles, so why charge more?

      Maybe user replaceable phone batteries are making a comeback, but with the way my phone is pretty much sealed up I wouldn’t trust myself to not break it. I’d also be leery of a third-party replacement lithium battery of unknown quality (let’s be honest, that’s what you’ll probably end up with) charging right next to my head while I sleep. Saying that as someone whose friend had a lithium battery fire with her laptop.

      Point is, the argument of “why would you try to save your battery by not using it when it has the same net effect of less battery?” is pretty short-sighted.
