A 'game-changing' new battery for electric vehicles (EVs) that charges in three minutes and lasts for 20 years could soon be coming to new cars.
Adden Energy, a start-up based in Waltham, Massachusetts, has been granted a licence and $5.15 million in funding to build the battery design at scale to fit in EVs.
The battery, developed by Harvard scientists, is lithium metal, rather than lithium ion found in EVs that are already on the market.
Its intricate design, inspired by a BLT sandwich, prevents the growth of troublesome 'dendrites' that grow in lithium-metal batteries and shorten their lifespan.
The new technology has been created by Xin Li and colleagues at Harvard John A. Paulson School of Engineering and Applied Science (SEAS).
Adden Energy was co-founded in 2021 by Li, along with William Fitzhugh and Luhan Ye, both of whom contributed to the development of the technology as graduate students in Li’s Harvard lab.
The startup aims to scale the battery up to a palm-sized 'pouch cell' – which has components enclosed in an aluminium-coated film – and then toward a full-scale vehicle battery in the next three to five years.
'We have achieved in the lab 5,000 to 10,000 charge cycles in a battery's lifetime, compared with 2,000 to 3,000 charging cycles for even the best in class now, and we don’t see any fundamental limit to scaling up our battery technology,' said Li. 'That could be a game changer.'
Lithium-metal batteries hold substantially more energy in the same volume and charge in a fraction of the time compared to traditional lithium-ion batteries.
But they're prone to the formation of 'dendrites' – tiny, rigid tree-like structures that speed up battery failure.
Researchers have therefore tried to harness the potential of solid-state, lithium-metal batteries, using a unique BLT-inspired design.

I don’t see where it says how much it costs to charge this battery, or any electric car.
Who keeps letting it infect other people?
Sure thing! Go away!
You also have a wild imagination.
Got your mach E yet?
Have fun with it!
And keep pushing those EVs.
They will be world changing for sure. 🙄
You mean a 110 V extension cord wouldn’t work? 🤪🧐😩😀🤭🤗
What could possibly go wrong? Reminds me a bit, of that guy who picked up a burning Willy Peter rocket, off the floor of a C-47, with his bare hands, and threw it out of the aircraft, before it exploded.
Do you suppose it could hold up the golden gate, by itself? 🤪🤭
I use soufflé batteries and somebody is always slamming the oven door.
And can’t catch on fire.
I think the tykes are slaving in the cobalt mines in Africa.
The even bigger market will be large yard equipment…leaf blowers, mowers, edgers, trimmers, snow blowers, sprayers, etc.
Yikes....I was born in Waltham! Bravo,Waltham!
Then there is the issue of cabling. Charging an EV in less than three minutes is one heck of an energy transfer. That energy has to travel through cables which would melt.
It’s about the funding and the research.
Once they make some “progress”, they’ll need more funding.
Good point. So the 200 amp service to my home would have to increase by about 42 times that to do 3 minute recharges at home. I’d need a 500 amp service or more to do 60 minute recharges and still power the home during recharges.
“Tesla recommends the use of water to put out EV battery fires.”
And that’s why the burn like Roman candles.
Electrical energy is measured in watts.

Now, imagine 10,000 cars across LA all charging at the same time...
Yeah, the line in the article "Adden Energy was co-founded in 2021..." isn't a flag.
The story of Elizabeth Holmes needs to be thrown in the face of every magazine and website who championed her for no reason other than genitalia.
