Department of Energy-Funded Ultrafast Lithium Battery Charges in Just Five Minutes
The Debrief ^ | JANUARY 29, 2024 | CHRISTOPHER PLAIN

New research funded by the Department of Energy has created a potentially revolutionary lithium battery that can be fully charged in only five minutes. State-of-the-art lithium-ion batteries, which power everything from mobile phones to electric cars, can take hours to fully charge, frustrating electric vehicle owners and high-volume phone users alike.

The Cornell University researchers behind the new lithium battery caution that the design has limitations, including a high weight that may make it impractical for some applications. Still, they say that their discovery could point the way to other materials that share the same fast-charging properties without the same limitations, potentially revolutionizing entire industries.

NEW LITHIUM BATTERY COULD CURE RANGE ANXIETY

Where mobile phones can be charged almost anywhere, and backup battery packs can dramatically increase usage times between charges, electric vehicles have yet to find an easy, practical solution to slow charging times. The result is a phenomenon that researchers call “range anxiety,” meaning a fear of taking electric vehicles on long trips due to the fact that recharging them could take hours.

To combat this phenomenon, electric vehicle manufacturers have increased battery sizes that can extend the miles between charges. Unfortunately, the added weight of larger batteries reduces their efficiency, resulting in even longer and slower recharging times to reach full capacity.

“Range anxiety is a greater barrier to electrification in transportation than any of the other barriers, like cost and capability of batteries,” said Lynden Archer, professor of engineering and dean of Cornell’s College of Engineering, who oversaw the project.

However, says Archer, if one can charge their EV’s battery in five minutes, one no longer needs to have a battery that’s big enough for a 300-mile range. “You can settle for less, which could reduce the cost of EVs, enabling wider adoption,” the professor explains.

NOVEL ELECTRICAL PROPERTIES ALLOW INDIUM-BASED LITHIUM BATTERY TO CHARGE IN MINUTES

To try to reduce EV charging times from hours to a few minutes, Archer’s team looked for a material that had the right mix of electrical and material properties to accomplish the task. They soon landed on a soft metal called Indium. While not currently used to make batteries, Indium is already widely used to create Indium-tin oxide that coats anything from solar panels to touchscreen displays. This means it is available at a reasonable cost and at an industrial scale.

According to the researchers, the key components making Indium a candidate for a fast-charging battery are an extremely low migration energy barrier, “which sets the rate at which ions diffuse in the solid state,” and a relatively modest exchange current density, “which is related to the rate at which ions are reduced in the anode.”

After fast charging their new lithium battery, the researchers observed its indium anode had a smooth lithium electrodeposition, whereas other anode materials can grow dendrites that impact the battery’s performance. “The key innovation is we’ve discovered a design principle that allows metal ions at a battery anode to freely move around, find the right configuration and only then participate in the charge storage reaction,” Archer said. “The end result is that in every charging cycle, the electrode is in a stable morphological state.”

By taking advantage of these two properties, Archer says they were able to create a lithium battery that charges in minutes and can be recharged thousands of times without losing significant capacity. If adapted to electric vehicle designs, they say that this type of battery could effectively eliminate range anxiety.

They are thinking more like 100 miles. Cut down on battery weight............

Available in a mere 20 years when the nuclear powered chargers are perfected.

But on the other hand, those batteries won’t be cheap.

Indium is about $5,000.00 an ounce these days.

Theoretically they could put Pebble Bed Reactors in cars and never have to stop for fuel or recharge, and it could power your home when not in use..................

That’s interesting.

The price I found is WAY higher:

Again nevermind, I read Iridium, not indium.

I’m just going to crawl away from commenting until I can learn to read. Sorry.

You would have to to charge a EV battery in 5 minutes. Too bad the pleebs will read this tripe and believe it. Critical thinking has left the chat.

“ EVs are losing favor with a rising number of Americans who don’t want to be tied to them. ”

The sane middle ground is plug-in hybrids. Plenty of range for (cheap) around-town travel, but you can still fill up as needed.

Of course, such hybrids being sane means the Dem mental cases hate the idea!

I think the auto companies will retrench in that direction, since EV demand has peaked for the time being.

You just have to love the law of unintended consequences.

The US power grid is not capable of supporting the mandate to move to banning the sale of new internal combustion engine vehicles between 2025 and 2030.

If you cut down the charging time to get the same amount of energy (kWh) stored in a battery for a certain distance (say 300 to 400 miles) then you are going to significantly increase the amount of power (kW) for the shorter charging time. That means that the current US power grid and almost all existing chargers will not be up for the job of charging the new batteries.

This is wonderful science, It meets a market need. If successful and implemented by the market, it also means that the critical path to significant EV implementation is now going to be much, much more difficult.

Do they burn at higher temperatures than 3600 degrees F? Are they easier to extinguish? Do they explode with as much force as conventional Lithium-Ion batteries when subjected to electrical shorts, external heat, sea water immersion, or undetectable internal battery damage? Will insurance premiums skyrocket? Will the government lie about range and safety threats? Questions to ponder.

Yeah I am pretty sure hybrids are and will be the most effective form of car for a long time to come

They are probably planning to put E-Cat cold fusion chargers out there for fast charging in 2075.

I’d blow a breaker trying to charge my cell phone in 5 minutes - I suspect that a car will take out a small town if trying the same.
