" 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.

    A typical phone battery is rated for about 500 (you can massively improve this by not charging it beyond 80%).

    This 80% thing is incredibly simplified and not even always accurate. Personally I charge to about 95% and my phone batteries remain at 98-100% condition after 2 years of everyday use.

    Limiting yourself to 80% doesn’t really make sense. You’re losing 20% capacity instantly, instead of losing it slowly over a few years. To be fair, a lot of people treat their devices so poorly that they may hit the 80% in less than 12 months, so I guess there’s that.
