Vacuum cleaner inventor and billionaire Sir James Dyson invested $15 million in battery start-up Sakti3, a company that’s developing solid-state batteries with much higher energy density than batteries currently available today.

Sakti3 is not only an investment opportunity, but maybe a source of new batteries for cordless devices produced by Dyson.

For now, Sakti3 is still in the development phase, fueled by a new $20 million investment round. Since its founding, Sakti3 attracted roughly $50 million in equity investments.

Sir James said:

“Sakti3 has achieved leaps in performance which current battery technology simply can’t. It’s these fundamental technologies – batteries, motors – that allow machines to work properly.

“The Sakti3 team has amazing ambitions, and their platform offers the potential for exponential performance gains that will supercharge the Dyson machines we know today.”

Ann Marie Sastry, founder and chief executive, said:

“It was an honour to be approached by Dyson because it wanted what we did – much, much better batteries.

“There is a great deal of knowledge and passion on both sides, and Dyson’s engineering team has the capability and the track record to scale up new ideas and make them a commercial reality.”

Okay, but what does this have to do with EVs?

Li-ion batteries are used in all sorts of consumer products, from cell phones to cameras to laptop computers… heck, even electric shavers.

Not all li-ion batteries are created equal. We spent about $40 for a small battery for our digital camera! On the basis of dollars per kWh, that would be astonishingly more expensive than the batteries being used in today’s EVs.

Let us please try to differentiate battery production for EVs from the general market for batteries. EVs demand low cost per kWh. Many other applications don’t.

“Okay, but what does this have to do with EVs?”

The same thing laptop batteries have to do with EV’s.

Yeah, like Jay says, “if it has a plug” it’s fit to print 😉

Maybe we’re confusing Dyson, with Drayson?

Actually I was referring to the “laptop” batteries Tesla uses in their packs. Sorry if it wasn’t obvious.

I thought it was.

GM has also invested in Sakti3, so maybe the story is GM is getting into the electric shaver business.

That would be a good April 1st story.

Clearly you missed the solid state buzz. It’s all about ease of production and therefore low cost ánd high energy density. Both very important for EVs.

Solid-state batteries might become EV batteries. Or might not. Who knows? Have to see how it plays out.

VW was interested enough to invest 5% into QuantumScape, another SS battery company.

“Okay, but what does this have to do with EVs?”

Solid State batteries or Li-S batteries will be next up in our EVs in the next 5 years or so. I’m beginning to think solid state batteries have taken the lead and will come out on top since they seem closer to commercialization.

False dichotomy. One is an anode, one’s a cathode. A cell needs both to run.

Very pleasing to see this. Indicates that Sakti3 is achieving it’s product development objectives, and is a real player in the battery market. Looking good for EVs after lower product risk high volume sales are achieved elsewhere.

For new technology – in this case hopefully significantly better energy density -you need to successfully go through the steps of conceptual, lab trials, then small scale demonstrations, then initial production and then scale up. Each of these steps has risk, but the investments required for initial and large scale investment are very large. Many technologies “fail” at those steps as noone is willing to risk the large investments. This announcement helps lower the risk that Sakti3 would fail at those steps just due to lack of access to serious capital investment. It might still fail due to a previously-unknown flaw – but that is always the case with new technology.

Why this matters to EVs, is that if they (Sakti3) succeed, we can look forward to a new potential path to longer range (or lower cost at the same range), in the next 2 or 3 years.

Dyson sees ahead more than most engineers. The same improvements that bring us 2x density in EV batteries will bring a revolution of another kind: There will be virtually no portable appliance that cannot run on batteries, from tools to kitchen and home appliances. This is a market worth billions.

Seems odd that a vacuum company should be among the first to invest in Sakti3. Considering the enormous potential of this tech (according to Sakti3) one would expect bigger players with much larger battery needs to be waving with much more cash than Dyson is investing.

It’s odd details like this that always make me wonder what’s really going on.

Private equity is a billionaire’s playground. You don’t have anyone, but yourself to fire you when you face the typical 1 in 20 odds of success. In perspective, the Knight just laid down ~.015 of his wealth.

First, the story should be corrected: It’s a $15M investment by Dyson Inc., not a personal investment by James Dyson the person.

Nothing strange about it. Don’t know if you were in the market for a vacuum recently, but something like half of current models are cordless… This is already a huge big market sector, and battery range (in running minutes, not miles) is currently a big limiting factor.

This isn’t unique — Black & Decker (a.k.a. DeWalt) also had a very close rerlationship with A123 and bought most of their output for several years for various rechargeable power tools.

All that said, Sakti3’s stated goal is EV batteries as well as consumer-appliance ones. It’s not surprising that they’re trying to do the 2nd goal first… This is new tech, so they need to make it work and productize it for the simpler case first…

Not really. A company with high demands like Apple or Samsung wont invest in Sakti3 because it needs to scale up first.

A premium vacuum company like Dyson will require on the order of 10-100MWh of battery cells per year (20Wh x 500,000 units to get to 10MWh). That’s all Sakti3 will reasonably be able to make at the high prices needed to scale up to small commercialization. As they work the kinks out of the system and reduce manufacturing costs, they can take larger orders for cells in the 100MWh-1,000MWh range at slightly more affordable prices.

Apple used approximately 2,500MWh of battery cells in 2014. You cant expect Sakti3 to go from 0 to 2,500MWh quickly and still have an affordable product.

Dyson is a fantastic man that deserves a lot of credit. He struggled against long established companies to produce its revolutionary vacuum cleaner until success. He then went on diversifying its products. All of them making something taken for granted in a new better and more efficient way. If he starts spreading out in other fields it can only be positive. I don’t know the man personally but he is one of those i would trust to break new grounds for sure.

It is so awesome to see so much effort put into batteries now:
– We have this Sakti SS battery.
-We have VW investing in QuantumScape SS battery company.
-We have Tesla pushing ahead with Li-Ions big time with the Gigafactory.
-We have LG Chem snapping up design wins with GM, Mercedes, and others.
-We have BYD investing big time in automotive Li-Ions and EV cars.

SOMEONE is going to come up with the right chemistry, manufacturing technique, supply chain, and/or other thing that brings us the sub $200/KWH cells.


But their products Suck.

One of the worst vacuums I’ve ever used, was a first gen Dyson upright. Got tired of having to take it apart to unclog it. 😛

“Developing” worries me, I wouldn’t throw to much money at “Developing” unless I had plans to buy controlling interesting once “developed”.

If they were “developed”, and he’s investing, I’d say “exclusivity deal”.

But, I’d like to get my hands on his “Digital Motor”, to see if it is scaleable.

Dyson is a smart guy, I wouldn’t be a bit surprised if there were cars in his future.
