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.

” It’s gonna require gobs of fossil fuels to produce the electricity.”
Fossil fuel consumption will drop due to shift away from fossil fuels in cars to EV’s which are more efficient and use energy supplies other than fossil fuels.
The laws of physics must be obeyed regardless how you store the energy. ( be it chemical energy or electricity) It will take a given amount to transport 4,000 pounds of cargo and car to go from one point to another. Sucking that energy out of the grid and then storing it in a battery in less than 5 minutes would be an incredible feat. What possibly could go wrong? If everyone charges at night those pretty fireworks will be transformers exploding throughout the grid. The electrical distribution system would collapse.

Another patron of Mother Jones and Amnesty Internation has come out of the woodwork.
If it really is efficient, makes electric cars more practical and more affordable, etc., the left will find a way to oppose it. The left only likes electric cars because it makes owning a personal car out of reach for many people.

Shhhh. You’re not suppose to do math.
Why start out with cars? If they can make a cell phone or a power drill that charges quickly and doesn’t expire after a couple of years, they can sell those and use thew proceeds to fund the car batteries.
“75 kilo watt hour charge in 1/6th hour would require a 450 kilo watt source.”
Where did you get that. Tesla is advertising 200 miles in 15 minutes. That would be 50 kwhr in 1/3 hour or 150 kw.
Their superchargers are rated for 250 kw. Others have chargers rated even higher.
Well!If that Battery last as long as its advertised that’s great but we still requier a massive amount of Electrical Power to charge up the Millions of potential Electrical vehicles the left wants to build.
They best start building a new generation of nuclear reactors soon or they can kiss the electric car goodbye.
“What would be neat is watching transformers getting hit with those spikes.”. It is not a spike.
Charge to last 20 years....
They said the first Covid jab would last forever and prevent the virus from infecting us.
Then, mostly less severe form of the illness and symptoms and only last two years, then one year, then under 6 months so “get the newly available booster.”
So now trust “science” and the government that the battery charge will last 20 years? We’ll see.
Believe it or not, I got a copy of that Pogue carburetor document and plans from an inter-library request, over 30 years ago.
I have a photocopy of it somewhere in storage.
“But the real fun would be putting out a lithium metal fire from a fire hydrant.”
Tesla recommends the use of water to put out EV battery fires.
As I keep telling Y’all this stuff will work......
As soon as the Legislatures / parliaments etc. of all major nations pass repeals of the laws of physics.
I’ve got a fair amount of experience in building (small) Electric vehicles... EVERY type of battery chemistry / construction: the faster you charge it the shorter its life will be, and I don’t care if it is modeled after a BLT or a PBJ or a chef salad or beef stew.
the question is the weight.
And recharge in 3 minutes? How much energy is coming from that charger?
” If everyone charges at night those pretty fireworks will be transformers exploding throughout the grid. The electrical distribution system would collapse.”
You have a wild, biased imagination!
I have a Tesla, so I’m not a naysayer. That said, the questions that remain about the practical hurdles for electric cars are legitimate and have not been fully addressed yet.
As you’ve pointed out, the performance characteristics of electric cars is remarkable, given the instant torque. I love the performance of my Tesla. However, I’m not convinced that I’ve done a great thing for the environment by buying one.
“They best start building a new generation of nuclear reactors soon or they can kiss the electric car goodbye.”
We have lots of spare capacity from 9PM to 9AM when most charging would be done. LOTS!
“So now trust “science” and the government that the battery charge will last 20 years? “
Are you drunk?
