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.

lemme guess the lithium comes from Ukraine
Actually “charger” not “charge.”
All of my post was ironic and sarcastic. I am saying not to believe the lies that the charger will last 20 years of use.
I am not drunk. I never, ever drink because my late mother was an abusive, narcissistic alcoholic and I don’t want to risk drinking.
i x e = w
Odd coincidence.
You and a radio person mentioned interlibrary loan, the library work in which I labored from 1969-2017. I never saw or heard it mentioned in my life and now twice in a few days. Odd.
Three times now...
“ would require 2 Megawatts of energy to be delivered to the battery”
What you meant was it would take a 2 MW charger operating for 3 minutes.
Thank you for your work!
I have had to reach beyond local libraries more than a few times, in my life, and such an exchange was sometimes priceless.
Aww, there you go, bringing Math into it!
Color me skeptical
“Love my EV but none of this means anything if we don’t have the electicity to charge these vehicles. It’s gonna require gobs of fossil fuels to produce the electricity.”
With batteries that last that long, and are compact, solar and wind energy finally become practical.
Gives you the ability to generate lots of excess solar electricity and store it and use the stored electrify when the sun don’t shire or the wind don’t blow.
If these reports are anywhere near the truth, it would be a huge game changer... and I would want to invest a bunch of money in that company.
Guees what else will also happen if this were to become reality? The econuts would be against it... because they’re against anything that actually works!
makes the dudes in Utah with their “cold fusion” BS sound sane.
...or by my PBR-sourced, sustainable one
Want to get this company ends up being another Solyndra, the government money is FLOWING NOW!!!
The only rapid-charge station will be located atop Hoover Dam.
1.21 gw fast-charge regular...
get = bet OOPS
I predict they will go far.............INTO DEBT
The picture above is a lot nicer than what was common when I was a telco central office equipment engineer in the early 80s. The batteries looked like a 30 gallon trash can made of a thick, transparent lucite. It was filled with acid and plates submerged. There were still SxS and #5 crossbar switches mixed with new #1AESS, Northern Telecom digital switches and D4 carrier banks. T1/T1C DSX cross connect panels were new installs at the time.
Now that you've pointed it out, I see no downside to curtailing fossil fuel power generation.
Sounds like recipie for Arc flash.
IF it actually works, the ChiComs will be producing it before an American company can. We pay for the development and they steal it and sell it back to us.
What was Huawei before they stole Nortel’s research? A third rate company in a fourth rate country! What did True-dolt do about the investigation into Nortel’s demise and how the ChiComs stole all its secrets? He shelved the investigation, like a good little globalist. TUCK FRUDEAU!
