'Game-changing' new battery for electric cars charges in 3 minutes and lasts for 20 YEARS - more than twice as long as current EV batteries

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.

Yeah, is it fireproof?

Wait until it catches on fire. Any water sprayed on it would react with the Lithium adding to the heat.

But where does the electricity come from? Kalifornistan has rolling blackout and doesn’t want the EVs they have now to charge overnight.

With the layering of metals and the quick charging, it sounds more like a supercapacitor.

Quick charge also means quick discharge: KABOOM!

It would be interesting to see the cable necessary to deliver the current needed to support that rate of charge.

Not the charger but the battery itself. The battery itself will supposedly put up with 20 years of charging and discharging.

I don’t know the specifics of this wonder battery but in theory if it can be charged at a much higher voltage, it wouldn’t need a lot of current.

In the early stages of design and funding for the space shuttle, NASA promised flights every week with a 3-4 day turnaround time for a refit and relaunch.

Guessing about 00000000 gauge, a soon-to-be hypothetical new size of wire. Probably about five feet in diameter. ⚡️

George Jetson was born this past July 31.

Martin McFly visited his own future seven years ago.

C’mon, people!
