The new CATL Qilin batteries are already producing cars at 140kwh delivering now, capable of 1000km or 621 miles [2]. A Tesla model S long range has 100kwh. This is with a Qilin battery at a density of 255 Wh/kg, but the expected density is 500Wh/kg [1] as they ramp up production and efficiency. This means we should expect around 1000 miles per charge over the next few years. There are other battery technologies on the 5 year horizon that bring another doubling. I would expect this translates into a few things: lighter cheaper cars with less batteries, cars that can travel long distances with faster charges (due to the battery being more depleted and not being charged fully on each charge), and long range trucks - and at the current thresholds electric aviation is practical and economical. Now we just need to create more electric potential!!

- tuatoru 3y ago> There are other battery technologies on the 5 year horizon that bring another doubling. I'm curious about these. Are you referring to silicon anodes, or metallic lithium anodes and solid ceramic electrolytes and "improved separators"? (I can't find much about the improvements.) Or other improvements, say in cathodes, or cell design (say reducing the mass of anode and cathode contacts), packaging or pack design? I thought LG's wireless within-pack BMS comms was a clever way to reduce volume, weight, and copper requirements. There are lots of incremental improvements possible, but getting from 500 to 1000 Wh/kg is a big ask. > Now we just need to create more electric potential!! The less-solved problem is essentially political: building more transmission grid. That involves landowners...
