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.

absolutely
its all total shite
You did not mention chargers.
Surely this battery system was not powering the 48vdc grid continuously? Life span of these would be nil. Had to have a battery charger from hell to keep them topped off
Of course all the switch gear in the nation (electric grid, pumping stations) use 12vdc charger battery BACKUP system
How do we charge and continue to charge these batteries? fossil fuel, not to mention the manufacturing of them and the car
“….EV’s which are more efficient and use energy supplies other than fossil fuels.”
LOL. My EV is powered by natural gas and a little coal.
Wait till the five million run out.
All you will have is a metal BLT.
Oh man, we can totally trust her!
Looks like a lot of fun - yikes
“Where did you get that. Tesla is advertising 200 miles in 15 minutes.”
They also say charge to 80%, don’t go below 20%, avoid using fast chargers unless necessary and avoid charging a hot battery when possible.
Old battery 4000.00 new battery 20000.00 ?
Ach, she runs best on Klingon dilithium crystals. And be sure both reactors are in phase or she’ll blow up and take half the planet!
Scotty
So it charges in 3 minutes and last 20years but how many miles will that charge get you? If you can only travel 30 miles per charge, what a bunch of crap!
I’ve been in a few central offices way back in the 1980s. Besides the switches- rows of them - the batteries and also a generator room. I think with the changes in technology there are a lot fewer such central offices.
How about when a thousand people plug in at the same time?
It is not the generation capacity but the distribution network that is the problem (in many neighborhoods). Unless you assume that cars will be charged overnight somewhere away from home.
Since there is no solar at night, the majority of electrical energy will come from traditional power plants, lowering the contribution of renewable sources.
I’m developing a battery based on my mom’s lasagna recipe. If it doesn’t work at least I can eat it.
I wonder if it might be another Nikola?
I’ll wait until these things are cheap to use, safe to run, dispose of, and are affordable should you need to replace one.
I won’t hold my breath while I wait.
Comes complete with flux capacitor. 🤪😆🤗 By the way, I went to Universal Studios and saw the clock tower in person. 👍
That’s Doc Brown territory. just need a lightning bolt.
