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.

Anyone know what the difference is?
Do you process lithium ore more to get metal than you do to get ion? Say a given ton of mined lithium ore converts to X amount of metal and/or Y amount of ion? Is it a cleaner, less costly process to produce the metal than it is to produce the ion?
Now, imagine 10,000 cars across LA all charging at the same time...
Whole state would go dark by the tenth one
I am sick of articles that lie to you in the headlines and disappoint in the text. The headline says very clearly that this exists: “new battery” “charges” “lasts”. That is the language used for something that already exists.
The truth is that it doesn’t exist. It is a concept.
Money is being spent to “build the battery design.” Not to “build the battery.” The article doesn’t give the source of the money nor the “licence”. Why is a license needed to design a battery?
How many gallons of water are required to put out a Tesla fire?

It’s why I call them
Urinalists.
They are on your leg
And call it rain.
They pee on your leg

Hey Tex, ever examine the innards of those transformers that hang from many power lines? They feature the very best of 1940s and 1950s technologies. You really believe they will handle the rapid transfers of massive electrical energy these new batteries are purported to require? You had better amend your build back better fantasy.
Are the battery life statements as accurate as the global warming figures? < /sarc >
Battery Capacity => 100KWH * 60minutes/hour = 6000KW-minutes
Recharging Power => P6000KW-minutes / 3minutes[charging time] = 2000KW = 2Megawatts
but a much bigger chance it will explode during charging ?
EVs the New Snake Oil
You will eat, bye and bye,
In that glorious land above the sky;
Work and pray, live on hay,
You’ll get pie in the sky when you die.
On weekdays, the “lots” of spare capacity time period is typically about 6 hours per day, midnight to 6am. There's some increased spare capacity available for about 2 hours before midnight and after 6am. At any time, the spare capacity can be instantly and radically reduced by a power plant completely tripping offline. Impossible? No.
I watched a modern 1500 megawatt cogeneration thermal plant trip off due to fire. Totally destroyed. The Texas Grid absorbed the electric loss in a fraction of a second then carried the load until a new construction cogen plant came online about 6 months later.
The cogen steam load was replaced in a day or so by a 1940 thermal plant that had been mothballed 10 years earlier. High level preservation with corrosion inhibitors, plumps and valves exercised regularly, antiquated controls maintained. After this last hurrah by the old power plant, it was demolished a year after its steam was no longer needed.
Economic impacts…. At the time, this chemical complex had revenues of something north of $100MM per month. Big place. Pulling a number out of the air, let’s say the grid could not absorb this additional load and the old, mothballed power plant was not onsite. Facility revenues reduced by $50MM per month and 5000 trained employees furloughed because the spare electricity and steam capacity was not available.
Things roll downhill and suppliers, service providers and external customers affected as well. Several 10s of thousands of other persons lost jobs and other companies had $500MM per month in reduced revenues. Shortages of certain consumer and industrial products led to retail inflation and another $500MM per month of adverse impacts.
The conventional electric grid should not and must not be treated so frivolously as is the latest fashion with green energy crap. There is a firm foundation to society that is dangerously being tinkered with. My opinions….
I’d have to see that to believe it.
More and more “breakthroughs” that never amount to crap.
“Hey Tex, ever examine the innards of those transformers that hang from many power lines? “
Those transformers on the poles won’t be loaded with superchargers.
“Actually, we don’t have 12 hours per day with “lots” of spare capacity. “

“To charge the same battery in 3 minutes would require 2 Megawatts of energy to be delivered to the battery!”
Just put a bigger breaker in your fuse box, problem solved!
With or without insulation? 😂😂😂
Yep hydrogen powered cars don’t need them BMW snickers.
