Amprius ships EV battery that reaches 90% charge in 15 minutes (electrek.co)

Amprius’ new SiMaxx cells hit an impressive 360 Wh/kg in energy density – far beyond the USABC’s target of 275 Wh/kg. What does that mean for EV drivers? Simply put, longer range without a bulkier battery. Plus, these cells have a power density of 1200 W/kg, meaning more efficient energy delivery.

Imagine how hot that fucker gets...

Right?

I’ll be so happy to see them in production, in actual cars and trucks

But holy moly how much power is going across that charger to do that? The heat pump would (I imagine) be going full tilt to keep up

1000 charge cycles. If you charge twice a week, that's 500 weeks or a little less than 10 years. There's no mention of degradation over time.

But back-of-the-napkin, it means for this to be cost-effective, they may want to come up with some sort of replaceable or battery swap system. Not sure anyone will want to buy a vehicle that needs a massive battery retrofit every 8-10 years.
