Volkswagen leveled up its EV battery enterprise in 2022 with its new in-house PowerCo department, and so they have been somewhat busy since then. Within the newest growth, PowerCo put a brand new stable state battery from QuantumScape by its paces. It handed with flying colours, bringing the stable state battery of the longer term one step nearer to now.

The New Stable State Battery From QuantumScape

QuantumScape’s EV battery journey has been a well-recognized identify on the CleanTechnica circuit. Just some months in the past, our editor Zach Shahan remarked,”We’ve been writing about QuantumScape in what looks like eternally.”

Contemplating the pandemic, it does seem to be something occurring earlier than 202o was eternally in the past. Nevertheless, as Zach famous, CleanTechnica first took a take a look at QuantumScape nearly precisely 9 years in the past, in January of 2015, once they first teased the concept of a stable state battery for electrical automobiles.

“The tubes have been buzzing over Volkswagen’s latest buy-in with the ultra-mysterious vitality storage startup QuantumScape, which business watchers describe as a direct problem to Tesla for the EV market,” we wrote.

“So, what’s all of the thriller about? If VW is difficult Tesla on EV battery expertise, you possibly can assume that VW has gotten wind of some type of disruptive expertise that may go away Tesla’s favored lithium-ion battery behind within the mud,” we added.

So, Was It Actually All About The Perovskite?

On the time, we theorized that there was a perovskite angle to Quantumscape’s new stable state battery. A little bit of noodling round at theestory.com — a web site which now not appears to exist — led to a remark thread on QuantumScape’s patent exercise.

“And, bingo, form of,” we wrote. “One of many patents is for this: ‘METHOD FOR FORMING AND PROCESSING ANTIPEROVSKITE MATERIAL DOPED WITH ALUMINUM MATERIAL.’”

Perovskites are one other acquainted face across the CleanTechnica desk. Although extra identified for his or her potential to push the price of photo voltaic cells manner down, perovskites have additionally begun to floor within the vitality storage subject, and that’s mirrored within the patent software. Right here’s a clip:

“Embodiments of the current invention supplies skinny movie and stable state electrolytes for lithium ion batteries. The formation and use thereof of antiperovskite materials permits a metallic lithium anode, which will increase the capability and subsequently the vitality density of any lithium-based electrochemical storage gadget.”

The Lengthy Journey To A New Stable State Battery

Properly, that was thrilling. CleanTechnica is reaching out to QuantumScape to see if perovskites are nonetheless in play. We didn’t see any hints on their web site, however for those who spot one thing drop us a word within the remark thread.

Within the meantime, QuantumScape has not been letting the grass develop underneath its toes all these years, although the corporate has had its fingers full managing expectations.

“Let’s begin by reminding readers that QuantumScape’s battery expertise continues to be within the growth stage,” the corporate’s CTO Tim Holme wrote in an explainer posted dated January 14, 2021.

“We’re at present testing battery cells with business dimensions of 70 x 85mm however solely as a single layer, i.e., one cathode, one solid-state separator, and one in-situ fashioned lithium-metal anode,” he defined.

“As famous in our SEC filings, there’s a lot work forward of us. Amongst different duties, we have to develop multi-layer cells and scale up our manufacturing capabilities,” he added.

Right here Comes The Stable State Battery Of The Future

In keeping with Holme’s timetable, sequence manufacturing of the brand new stable state battery cells might begin in 2024. That is still to be seen, however the brand new PowerCo take a look at signifies that issues are operating alongside near schedule.

The take a look at concerned a stable state battery cell consisting of 24 layers, which is the setup for sequence manufacturing. “The following step on the way in which to sequence manufacturing is now to excellent and scale the manufacturing processes,” Volkswagen explains.

Volkswagen was awfully excited to share the outcomes of the take a look at. “The U.S. firm QuantumScape has not too long ago reached an essential milestone, which was now confirmed by PowerCo: its solid-state cell has considerably exceeded the necessities within the A-sample take a look at and efficiently accomplished greater than 1,000 charging cycles,” Volkswagen acknowledged in a press launch on January 3, 2023.

“For an electrical automotive with a WLTP vary of 500-600 kilometres, this corresponds to a complete mileage of greater than half 1,000,000 kilometres,” they enthused. “On the identical time, the cell barely aged and nonetheless had 95 % of its capability (or discharge vitality retention) on the finish of the take a look at.”

“QuantumScape’s solid-state cell considerably exceeded these specs within the newest take a look at,” they reiterated, referring to the goal of 700 charging cycles and a 20% most capability loss for brand spanking new battery cells at this explicit stage of growth.

Half 1,000,000 kilometers is equal to 310,685.596 miles, which we are able to spherical as much as 311,000 miles since Volkswagen did say “greater than.”

Driving habits range significantly by age and gender. Right here within the US the height annual common amongst demographic teams is about 19,000 miles per 12 months, which works out to 16 years’s value of driving.

In keeping with Kelley Blue E-book, the common size of automotive possession is at present 8.4 years. So, if the determine of 311,000 miles pans out, it’s probably {that a} US driver would get uninterested in their automotive and promote it lengthy earlier than the battery wears down.

Simply saying.

And, Right here Come The Gigafactories

As for that factor about difficult Tesla, that additionally stays to be seen. However, Volkswagen and PowerCo have plans.

The QuantumScape stable state battery was examined on the PowerCo labs in Salzgitter, Germany, the place the corporate can also be hatching plans for a sequence of six vertically built-in, soup-to-nuts battery manufacturing facilities, from uncooked supplies on by to recycling.

“Every manufacturing unit shall be operated one hundred pc on electrical energy from regenerative sources and shall be designed for future closed-loop recycling,” PowerCo explains, with a specific emphasis on recycling end-of-life batteries. The general plan additionally entails large-scale stationary vitality storage techniques, so presumably the recycle angle would apply to that angle, too.

Salzgitter would be the house of PowerCo’s first cell manufacturing unit, to be adopted by one other in Valencia and three others at European areas to be named later, with six deliberate in all. The Salzgitter manufacturing unit alone shall be able to offering sufficient batteries for 500,000 EVs per 12 months when absolutely constructed out.

The corporate additionally dropped a touch about plans for the US, stating that “PowerCo can also be already exploring the opportunity of additional gigafactories in North America.”

Stable state battery followers could have to attend just a little longer to get their fingers on a Volkswagen with a stable state battery parked inside, however within the meantime they are able to profit from Volkswagen’s new “unified cell” technique for standardizing and simplifying battery design, which is predicted to trim prices by as much as 50%.
