PowerCo Assessments QuantumScape’s New Strong State Battery For EVs

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

The New Strong State Battery From QuantumScape

QuantumScape’s EV battery journey has been a well-recognized title on the CleanTechnica circuit. Only a few 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. Nonetheless, as Zach famous, CleanTechnica first took a have a look at QuantumScape nearly precisely 9 years in the past, in January of 2015, once they first teased the concept of a strong 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 trade 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’ll be able to 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 strong state battery. A little bit of noodling round at theestory.com — an internet site which now not appears to exist — led to a remark thread on QuantumScape’s patent exercise.

“And, bingo, kind 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 recognized for his or her potential to push the price of photo voltaic cells method down, perovskites have additionally begun to floor within the vitality storage discipline, and that’s mirrored within the patent software. Right here’s a clip:

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

The Lengthy Journey To A New Strong State Battery

Nicely, 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 in case you spot one thing drop us a word within the remark thread.

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

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

“We’re presently 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 Strong State Battery Of The Future

In response to Holme’s timetable, collection manufacturing of the brand new strong state battery cells might begin in 2024. That is still to be seen, however the brand new PowerCo check signifies that issues are working alongside near schedule.

The check concerned a strong state battery cell consisting of 24 layers, which is the setup for collection manufacturing. “The following step on the best way to collection manufacturing is now to good and scale the manufacturing processes,” Volkswagen explains.

Volkswagen was awfully excited to share the outcomes of the check. “The U.S. firm QuantumScape has lately reached an vital milestone, which was now confirmed by PowerCo: its solid-state cell has considerably exceeded the necessities within the A-sample check and efficiently accomplished greater than 1,000 charging cycles,” Volkswagen said in a press launch on January 3, 2023.

“For an electrical automobile 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 similar time, the cell barely aged and nonetheless had 95 p.c of its capability (or discharge vitality retention) on the finish of the check.”

“QuantumScape’s solid-state cell considerably exceeded these specs within the newest check,” they reiterated, referring to the goal of 700 charging cycles and a 20% most capability loss for brand spanking new battery cells at this specific 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 fluctuate 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 response to Kelley Blue E book, the common size of automobile possession is presently 8.4 years. So, if the determine of 311,000 miles pans out, it’s doubtless {that a} US driver would get bored with their automobile 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 strong state battery was examined on the PowerCo labs in Salzgitter, Germany, the place the corporate can be hatching plans for a collection of six vertically built-in, soup-to-nuts battery manufacturing facilities, from uncooked supplies on by means of 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 selected 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 dwelling of PowerCo’s first cell manufacturing unit, to be adopted by one other in Valencia and three others at European places 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 totally constructed out.

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

Strong state battery followers might have to attend somewhat longer to get their arms on a Volkswagen with a strong 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 anticipated to trim prices by as much as 50%.
