Only a few days in the past, we printed an article about Ample, the Silicon Valley firm that’s selling battery swapping for electrical automobiles as a option to cope with the problem of maintaining them charged up and able to drive wherever as wanted. Maybe we’re prescient, however we’ve got mentioned on a number of events that higher batteries are coming that may make vary and charging anxiousness a factor of the previous. Right now comes phrase that Prieto, a startup based mostly in Fort Collins, Colorado, has unveiled a prototype of a battery it says works at -30º F in addition to it really works at temperatures above 100º F.
That’s excellent news, however what’s much more thrilling about Prieto is that its 3D batteries might be totally charged from 0 to 100% in simply 3 minutes and are nonflammable. In a press launch, Preito says all its claims have been independently verified by a 3rd get together accredited battery testing lab.
What Is A 3D Battery?
On its web site, Prieto says, “Right now’s batteries are 2D, that means vitality solely flows in a single course over a two dimensional airplane. To cost, ions should stream from one floor to the opposite, leading to severe limitations. Thicker batteries maintain extra vitality however the lengthy ion pathway means gradual charging. Thinner batteries can cost quicker however can’t maintain a lot vitality.
“We reimagined a battery’s structure and have designed the world’s first really 3D battery to ship 360 diploma ionic switch. Very brief ion pathways with out compromising floor space means each hyper-fast charging and excessive vitality density.”
Right here’s a video that explains this new know-how.
“Prieto’s battery will cost quicker than you’ll be able to fill your automotive’s fuel tank,” mentioned Mike Rosenberg, Prieto CEO. “Whenever you cost your automotive quicker than gassing up, vary is now not a hindrance and everybody turns into a possible EV purchaser. A 3 minute cost essentially modifications how corporations can design their merchandise and the way customers use them.” He claims the speedy charging functionality applies to any measurement battery.
“Prieto is the one battery that we’re conscious of that won’t solely function however can even cost at -30 levels Celsius,” defined Rosenberg. “As we realized this previous winter when excessive chilly climate hit North America, many individuals have been left stranded with lifeless EVs. Our battery would have allowed these EVs to proceed to function and cost, instilling confidence in drivers to depend on their EVs even in excessive temperatures.” Truly, across the CleanTechnica smokeless firepit, we don’t recall a variety of tales about lifeless EVs final winter, in order that half appears to be hyperbole. Hopefully, the claims for the Prieto battery are actual, not puffery.
The corporate says its 3D structure and design make sure the battery will not be flammable or flamable. A 3rd get together lab performed the gold commonplace “nail penetration take a look at” on the Prieto battery. Not solely was there no hearth or explosion, the battery continued to function.
“The Prieto battery operates safely and won’t catch hearth like conventional lithium ion batteries,” Rosenberg mentioned. “The 3D structure and the supplies we use be certain that our batteries won’t expertise thermal runaways or fires, which provides customers peace of thoughts.”
“Our founder, Dr. Amy Prieto, reimagined your complete structure of a traditional battery and developed the primary 3D inter-digitated battery,” mentioned Rosenberg. “We’re introducing a greater structure and a greater course of, which leads to a greater battery and a superior client expertise. That is really the following evolution that may redefine the best way we energy our lives.”
The Previous, The Current, & The Future
Prieto’s 3D structure is totally completely different from all different batteries, the corporate says. Right now’s batteries use a decades-old 2D structure that should at all times be a compromise between vitality storage and quick charging. “We now have dramatically shortened the diffusion size in any course, which takes charging to hyper-speed and delivers extra energy and vitality storage than 2D batteries,” mentioned Dr. Prieto, founder and chief know-how officer of Prieto. “The core of our battery seems like a skinny copper sponge, and the ions solely need to journey from one strand to the following, a fraction of the space in conventional 2D batteries.”
Prieto’s battery is designed to ship 5 occasions the facility density (20C discharge charge) and as much as 3 times the vitality density of typical 2D batteries. It’s customizable to any measurement or software, making it superb for something from electrical automobiles to energy instruments, medical units to cellphones and small house home equipment.
Prieto Options Easy, Low Price Manufacturing
The brand new Prieto battery is made out of low price, sustainable supplies utilizing a easy and scalable course of. Prieto makes use of a confirmed water-based electroplating course of at room temperature and its course of requires no dry rooms, clear rooms, or different costly gear.
“From day one I prioritized manufacturing forward of the battery design, and I knew to reimagine the battery we might first need to simplify manufacturing to scale up rapidly, effectively, and affordably,” mentioned Dr. Prieto. The manufacturing yield charge on the firm’s current laboratory is greater than 90%.
“We now flip our focus to commercialization as we finalize plans to construct our pilot manufacturing facility,” mentioned Rosenberg. “Our excessive yield charges, mixed with our easy and acquainted manufacturing course of utilized in many different industries, will finally end in a lot decrease prices than conventional lithium-ion batteries and offers us an ideal diploma of confidence.” Prieto says it’s at present in discussions for manufacturing and purposes with potential companions.
Prieto says on its web site that in contrast to most batteries at the moment, that are made utilizing hazardous supplies and costly gear corresponding to dry rooms, clear rooms, and excessive temperature processes, it began not with the battery however with the manufacturing course of. “Our aim was easy — develop a extremely scalable course of utilizing low price sustainable supplies. Our patented course of makes use of water, electrical energy, and gentle chemical substances like citric acid at room temperature. The method is straightforward and scalable,” the corporate says.
We see a variety of battery information come throughout our desks right here at CleanTechnica. A number of the breakthroughs are actual and a few are an phantasm. Prieto has not come up on our radar earlier than, so we’ve got no monitor document we will depend on.
We do know that corporations like QuantumScape and StoreDot have been engaged on new and improved battery know-how for years, however their batteries haven’t but been put in in any manufacturing automobiles, to the most effective of our information. Earlier this month, CALB launched what it calls its U formed battery, which it says dramatically shortens how far electrons need to journey between the cathode and the anode. The corporate says the shortened pathways imply the brand new batteries might be recharged in ten minutes.
Higher, cheaper, quicker charging batteries are coming, there’s little doubt about that. Will Prieto be a reputation that defines the brand new period of batteries the best way CATL does at the moment? “We’ll see,” mentioned the Zen Grasp.

Former Tesla Battery Skilled Main Lyten Into New Lithium-Sulfur Battery Period — Podcast:
I do not like paywalls. You do not like paywalls. Who likes paywalls? Right here at CleanTechnica, we carried out a restricted paywall for some time, nevertheless it at all times felt unsuitable — and it was at all times robust to determine what we must always put behind there. In principle, your most unique and finest content material goes behind a paywall. However then fewer individuals learn it! We simply do not like paywalls, and so we have determined to ditch ours.
Sadly, the media enterprise continues to be a troublesome, cut-throat enterprise with tiny margins. It is a endless Olympic problem to remain above water and even maybe — gasp — develop. So …
