    The factory making these is still like 6 years out. The ones on market are like 65% energy dense, and lithium tech has only gained a few percent a year, so I don’t know where you’re getting your thoughts from. For EV’S, sodium ion is going to be a far shot behind solid state. By the time sodium could catch up to being close to today’s lithium batts, solid state will be far cheaper and have a huge power density advantage.

            It’s actually been about 8% in recent years, but historically 5%. We’ll see which one holds, but either compounds to doubling capacity in shorter time than you might think.

              yeah, you would expect it to slow down over time, given the ever encroaching theoretical limits of technology, but obviously that depends on how far that is from here. Otherwise you generally expect to see an increase likely proportional to the amount of sold product (more R&D funding) as well as a function of competition, which is pretty high right now.
