This is a pro-electric blog so has been unkind to ignorant detractors. We do admit that we are in no hurry to purchase a Tesla or a Volt for ourselves.
Penn State says they've made some power-cells with faster recharge. This because they're smaller - cheaper, too. However that also means they're 50 kWh rather than 150 kWh. Unsure how it compares with solid-state, implicitly faster recharge with the same weight.
That means they've reduced mass and pump-time by... a tank with a third the capacity. And I think they're still using lithium (and cobalt) rather than more-powerful and cheaper sodium. On the other hand the smaller cells do seem (much) easier to modulate so require disproportionately less surrounding electronics.
To go across country, EV-owners are already reinventing the diesel-electric train which, as Stephen Green points out, is stupid
.
Although, less stupid: a smaller cell as charges faster might find use in a hybrid vehicle - already widely found on the road, but with similar MPG as a 2010 Honda. Also brought to mind is the difference between a "cell" and a "battery": three smaller cells should restore to us the 150 kWh with less concern for modulation. And they should recharge in parallel, during the same overlapping timespan.
INSURANCE 3/28/23: If batteries aren't cheap, they can't be insured. I don't believe any way exists to fix a powercell.
