> 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...
