I read about this cell a couple of days ago and I got super excited because the article mentioned that the battery could deliver that power at 25C (25 times the capacity of the cell, or 100 Amperes for a 4Ah cell) but I have just read the press release of the manufaturer and it says the cell can deliver that energy at 25°C - degrees Celsius... thats a big difference.

25C would be incredible but it's still good enough for aviation and cars. I think I saw 10C.

Wow, 10C? That would be a huge improvement. Possibly already more than one could reasonably utilize, at least on an EUC. I suspect the price will be eyewatering though, if the first customer is the next best thing to space industry.

They're building a factory that's supposed to produce 5 GWh/year, hopefully that will help with the cost. Still nowhere near Tesla Gigafactory levels but it's a start.
They say it plugs into normal battery production lines, I'm wondering if Tesla could license it and adapt their factories.

The following submission statement was provided by /u/ObtainSustainability:
Fremont, California-based Amprius announced it has verified the performance of its silicon anode battery cells with third-party tester Mobile Power Solutions. The results indicate that this cell model provides 504 Wh per kg and 1321 Wh per L at 25 degrees C.
Amprius said the silicon anode cell is roughly half the weight and volume of leading conventional commercially available lithium-ion cells.
The cells have applications in the fast-growing electric aviation space and could later be integrated with electric vehicles. Together, electric aviation and light-duty EV battery demand is estimated to exceed over $100 billion globally by 2025, said the company.
The Amprius cells offer a run time of 200% compared to leading graphite battery cells, while being lighter and smaller than other batteries with the same energy content.
“...technology that will ultimately revolutionize how high we fly, how far we travel and how long we can use our devices,” said Jon Bornstein, president of Amprius Labs.
The battery cells are planned to be integrated with the AALTO Zephyr, a high-altitude platform station (HAPS). The solar-electric telecommunications aircraft offers persistent earth observation with 18cm ground sampling distance, near-real-time video and imagery from the stratosphere, day and night.
Amprius operates a research and development laboratory in Fremont, California. It recently signed a letter of intent for a 774,000 square foot facility in Brighton, Colorado that would provide up to 5 GWh of manufacturing capacity.
The Department of Energy (DOE) targets improvements in battery performance to stabilize the critical materials supply chain and offer attractive products to vehicle buyers. “While a number of electric drive vehicles are available on the market, further improvements in batteries could make them more affordable and convenient to consumers,” according to the DOE.
