Amprius Battery Is Most Energy Dense Battery: Could Accelerate eVTOL Production

Sandy Munro shares information about the most energy dense battery we've seen. It's a battery from Amprius at 500 Wh/kg.

The Amprius Battery

Sandy Munro just shared a video of breaking news about a 500 Wh/kg battery. The people at Amprius released some information about battery technology, and it is staggering. Sandy was with Anthony from his company and talked about this new battery.

It is a 500 Wh/kg battery. It uses a silicon anode platform with their lithium-ion chemistry. The 500 Wh/kg is unprecedented in the battery industry.

How does this battery compare to the rest of the industry. Here are the numbers:

Wh/kg numbers:
* Tesla 2170: 242
* 2170 Rivian: 259
* 4680 Tesla: 233
* Pouch (Ford): 285
* Amprius: 500

The 4680 Tesla number is a little lower because Tesla took silicon out of the anode. Sandy Munro says this is a big deal and says that nobody has anything quite like this for the marketplace. There is a new 775,000 sq. ft. facility in Brighton, Colorado, and it will produce about 5 GWh of capacity each year. It has already been tested through the various subsidiaries and situations to prove it.

Amprius is making these batteries now and this is how they are manufactured.

Amprius is using silicon, which is replacing graphite. Graphite is difficult to get right now. The rest of graphite comes from China. Silicon is about the best thing you can attach lithium to. Sandy says that in looking at this, this battery is in production right now and nobody has anything close.

So why is this a big deal? The reason this is a big deal is that these batteries are powerful enough and dense enough to accelerate eVTOL (electric vertical take off and landing aircraft) transportation. Sandy is going to call ASX to let them know about this battery pack to see if they want to use it for their eVTOL's.

They are using the silicon nanowires, and they are coating it with a resin like material to keep it stable. Using a first principle's aspect, they are going from a most Energy dense material that can hold a lot of lithium - silicon. It can hold about 7 times more lithium than graphite. That's how they are able to achieve this.

Lithium will swell with the amount of lithium it absorbs, and they can get around it with the nanowires with the protective coating. Sandy had not heard of this company because they are mostly in the aerospace industry.

Aircraft needs everything as light as possible and as Energy dense as possible, and aircraft will pay a premium for this kind of battery, meaning they will pay much more money for the battery.

Sandy is going to go visit Amprium and talk to them in greater length, but wanted to get this information out there. I think this is exciting news for the aerospace industry and is good news for the potential of eVTOL's.

Most cars aren't going to use, unless it is a very expensive premium car, because these Amprium batteries will be way too expensive for a car for the everyday consumer. But aircraft are another story.

What do you think of this battery? Will it accelerate production of eVTOL's?
