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.

Wait until they see my PBJ-inspired battery.
“Still at the rainbows and unicorn farts stage, but you never know ...”
Tesla S: 200 mph, 400+ mile range, 0-60 1.9 seconds. Quarter 9.2 seconds
Roadster: 250+ mph, 620 mile range, 0-60 1.9 seconds.
Present batteries have lifetimes much longer than quoted above.
Lithium-ion batteries are already going away.
A Tesla model X has a 100 kWH battery. It would take 100 kW of power for 60 minutes to recharge, ignoring losses.
To charge the same battery in 3 minutes would require 2 Megawatts of energy to be delivered to the battery!
I’m still waiting for Popular Mechanics to publish plans for a 200 mpg Pogue carburetor. It’ll be great!
and weighs less than 10 pounds, fits in the palm of your hand, and costs only $9.95 ... heard it all before, dozens of times over the last three decades ... none have ever happened ...
I was going for a club sandwich version but so far it’s a turkey.
You know you’re not supposed to confuse the masses with facts...
My Four Roses Bourbon Old Fashioned just ended up on my 32" 4k monitor.
You owe me! LOL!!
It still needs a more common and recyclable metal than lithium.
If they take the battery from my car, it should be shipped off and packaged into a new battery that will have similar performances. Otherwise, it’s ultimately a dead-end technology over the long term.
Sure it does. I’d like to see the panel and cable that will charge an 11kw battery in 3 minutes. The lights are going to dim across town when you plug it in.
“’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, “
Tesla has demonstrated a battery that has gone 2,000 cycles with no degradation in capacity. Based on an expected life of 13,000 cycles they are projecting 100 years/ 1 million miles.
Musk says when your car wears out, you can get a new one and put your old battery in it!
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.
Let me know when they’ve figured out dilithium...
CC
They hope to scale up to a small pouch sized battery???
So it’ll run a Toni’s truck?
“2 Megawatts of energy”
Megawatts is a measure of power, not energy.
The child laborers in Africa are going to love this.
i’m guessing it’s a small test cell for which i dint see a specified size/capacity, so...
The Long Range Tesla Model 3, capable of over 300 miles of range, comes with a 75 kWh battery pack. 75 kilo watt hour charge in 1/6th hour would require a 450 kilo watt source.
Electrical power is given by P=VI
So a 220 volt circuit would need an amp rating of
I = 450,000 / 220 = 2045 amps
Well, no problemo.
What would be neat is watching transformers getting hit with those spikes. I’m sure the grid is robust enough.
But the real fun would be putting out a lithium metal fire from a fire hydrant.
