>Tesla's current Model 3 cells (the best comparison to date) hold around 260 Wh/kg and 730 Wh/l, whereas Amprius' new cells hold 450 Wh/kg and 1,150 Wh/l — a significant jump up.

I am by no means an EV fan but this is exciting. A 74% increase in energy density. But we dont have recharge cycle count and cost though.

I wonder when we could see this on Laptop and Smartphone or Tablet? I am willing to pay $100+ RSP for revolutionary battery. Not a lot since it is only 3x increase in battery BOM.

Let me know when I can actually buy them commercially.

Why are you not an EV fan?

fossil fuels have literally 50x the energy density, take 3 minutes to "recharge" vs hours. Even a supercharge is too long for a roadtrip. Gas vehicles don't lose 20-30% of their range in cold weather. Those are the big reasons.

Before I thought about Lithium batteries in EVs, I thought about liquid acid batteries.

It would be easy enough to have "gas" stations where you could drain the elecrolyte fluid and refill with recharged fluid.

"Recharging" an EV would then only take a few minutes like pumping gasoline.

Batteries for cars are dumb. Wait! Hear me out.

Batteries are expensive, heavy, and very difficult and dangerous to dispose of. Crashed EVs can spontaneously ignite days after the crash that damaged them. Wrecking yards and such are already having to deal with this issue. Firemen and other first responders have to deal with this when trying to clear EV car crashes off the highway.

Alcohol, on the other hand, has waaaaaaay more energy density, the byproducts of combustion are non-toxic, anyone can make it with household materials, and since it's made from plants all the energy is solar and it's carbon-neutral. Also, most ICE cars can be easily modified to use it.

It used to be common for farmer to grow their own fuel.

Alcohol fuel makes sense as part of a regenerative local economy. Imaging something like a Community Supported Agriculture (CSA) farm that delivers gallons of fuel as well as groceries. Check out "Alcohol can be a Gas" for more information http://alcoholcanbeagas.com/ (I'm not affiliated with them, I took a Permaculture course from the author many years ago, that's how I first heard of the idea.)

Cool. But to 'beat Tesla' they'd have to make a price point, a weight per kWH, a safety check, heat restrictions and on and on.

Making a better battery - been done lots of times. Shipping in quantity, on time, at a price is a different matter.
