Solid-state battery developer Quantumscape reported that it has made and is currently testing its first 10-layer cells in a commercially relevant (70x85 mm/ 2.8x3.4 inches) form factor. The cells are being tested at 1C and C/3 (one- and three-hour charge and discharge) rates under standard temperature (25 °C) and pressure (3.4 atmospheres). Quantumscape believes these conditions are relevant for automotive applications.

The 10-layer cells demonstrate early capacity retention and recycling behavior similar to what Quantumscape has already shown for single- and four-layer cells.


In its Q2 2021 letter to shareholders, Quantumscape said that the 10-layer results were enabled by a series of manufacturing innovations resulting in a step-function improvement in separator consistency and quality—a key recent focus of the development team. Leveraging the reusable prismatic can package design introduced earlier this year, contributed as well; Quantumscape is using this package design for both 4- and 10-layer cells.

Qs2

10-layer cell on test


We had set ourselves the goal of showing results from 10-layer cells by the end of 2021, so we are encouraged that we have the first 10-layer cells this early. This reflects a rapid rate of progress over the last few quarters, with single-layer results in December, followed by four-layer results in February, and now 10-layer cells in July. We will seek to continue to improve the performance of the 10-layer cells through the rest of 2021, including ongoing improvements to the quality, consistency, and throughput of our separator, demonstrate several dozen layers in 2022 and produce test cells for vehicles on our QS-0 pre-pilot production line in 2023. We believe accomplishing the improvements described above and translating them to our new, higher throughput tools will be key to achieving our goals for this year and next.

LFP cathode. Quantumscape also announced that it made and tested an anode-free lithium-metal cells with a low-cost iron phosphate (LFP) cathode and confirmed that its chemistry and cell design are compatible with LFP.

Although LFP has seen a resurgence of interest, traditional LFP cells using carbon anodes generally suffer from low energy density (typically around 400 Wh/L). Quantumscape believes LFP coupled with its lithium-metal anode could deliver energy densities between 600 and 700 Wh/L, approaching today’s state-of-the-art NMC chemistries.

A lithium-metal anode is a natural fit for a lower voltage cathode chemistry like LFP, which would otherwise need thick conventional anodes to deliver high energy. We believe this demonstrates the commercial flexibility of our cathode-agnostic solid-state lithium-metal platform, which allows us to extend our product offering to a broad spectrum of the automotive market.

UK-based Clean Air Power, a provider of clean transport solutions, is marking its 25th anniversary working with hydrogen injection products by releasing a new range of hydrogen injectors for internal combustion engines. The range, which digitally controls hydrogen gas flow into engines, includes a high-pressure direct hydrogen injector that complements Clean Air Power’s existing hydrogen port injector options.

Clean Air Power is naming the extended range DigiJet H2ICE, which will replace its existing ‘ServoJet’ products. This next-generation of products represents an evolution of the current technology, bringing recognized reliability and durability to hydrogen injection and offering a compact and affordable solution.

DigiJet products can be used across a wide range of industries including on-road, off-highway, rail, maritime and motorsport. The release of a hydrogen injector that doesn’t require lubricant helps address the challenges of delivering hydrogen into the combustion chamber of an engine, as well as assisting the increasing move away from fossil-fuel dependence.

The injectors can be provided in configurations and ratings to suit a range of applications.

The addition of direct injection capability to our portfolio is a key step for us, opening up a wide range of new green fuel applications such as hydrogen and ammonia. Our technology has revolutionized gas injection and fluid control during the past quarter of a century, creating new markets for low carbon gas and digital hydraulics. DigiJet will further our reputation for developing affordable, multi-application solutions.

—Dan Skelton, CEO of Clean Air Power

Clean Air Power DigiJet Precision Injectors are widely used in the natural gas industry for multi- and single-point gas injection and are certified to the European standard ECE R110. All natural gas injector body and internal parts are constructed from stainless steel with maximum operating pressure differential ranges from 75 to 300 psi. Options include drop-in mounting, with flying pigtail leads or quick connection applications, while coils are available for 12-24v DC. Every unit is thoroughly tested for flow delivery, pressure leaks and performance.

House Passes Debt-Limit, Government Spending Bill, Sends It To A Senate Showdown

As expected, in a surprisingly close, 220-211 vote, the Democratic-controlled House passed a bill that would suspend the U.S. debt ceiling into December 2022 and provide the government funding to operate past Sept, 30 if it passes the Senate which it most likely won't because Senate Republicans, even RINOs such as Mitt Romney, have vowed to block it over the debt limit provision which Democrats purposefully included in the provision.

The political standoff raises the chances of twin fiscal disasters -- a government shutdown and a default -- that could have devastating consequences for Wall Street and the broader American economy.

It's not yet clear what Democrats' plan B would be if the effort to avert a shutdown and suspend the debt limit runs aground in the Senate, as it appears is on track to happen.

If Machin sides with Senate Republicans to block the stop-gap funding measure over the debt limit, there could still be enough time to strip the debt limit measure out and pass a stand-alone spending bill to avoid a shutdown. But the vote would take place perilously close to the shutdown deadline - the drop dead date is sometime in mid/late October - and would likely require cooperation on both sides to process a quick Senate vote. It also would leave the debt ceiling problem unresolved, setting up yet another flashpoint issue to be dealt with by Congress in the weeks to come.

And just to assure that the bill in its current format will not get the support of republicans, moments after the House vote, Senate Republican Leader Mitch McConnell and Republican Senator Richard Shelby introduced a new stopgap measure that keeps the U.S. government funded through Dec. 3 but does not suspend or increase the debt limit.  The Senate bill includes funding for disaster aid, assistance for Afghan allies and Israel’s Iron Dome missile defense system, a provision which was struck from the Democrats' bill to obtain support of progressive democrats.

Earlier on Tuesday, House Majority Leader Steny Hoyer left the door open on what measures the House would take if the Senate is not able to pass what the House sends over before the government runs out of funding next week.

"We want to send it over to the Senate, and give the Senate an opportunity to consider it, figure out what they're going to do and they may send it back to us, at which point in time we will have to make a determination, but we want to pass that bill," he said.

Meanwhile, as reported earlier, the current standoff in Congress makes a government shutdown and a debt ceiling breach increasingly likely according to Goldman, which said in a note published overnight that while "a shutdown October 1 is not the base case, in our view, because there is a fair chance that Democrats will shift strategy before the deadline. However, the longer Congress remains on this course, the more likely a shutdown becomes."

Gungnir Resources Inc. [GUG-TSXV, ASWRF-OTC PINK] shares rallied in active trading Tuesday after the company released additional high-grade nickel results from continuing drilling at its Lappvattnet nickel deposit in Sweden.

Tuesday’s results are expedited assays from hole LAP21-05, located 40 metres along strike from hole LAP21-02, which intersected 3.19% nickel over 4.25 metres.

Drilling highlights from hole LAP21-05 include 2.62% nickel over 5.65 metres within a 14.00-metre interval, grading 1.40% nickel. This drill hole returned high-grade nickel intercepts less than 60 metres below surface.

Gungnir shares advanced on the news, rising 41.6% or $0.05 to 17 cents on volume of 3.68 million. The shares are currently trading in a 52-week range of 13 cents and $0.04.

The Pappvattnet and Rormyrberget nickel deposits are located in the eastern part of the Vasterbotten District, 60 kilometres and 100 kilometres respectively east of the company’s Knaften gold exploration project. The deposits are held 100% by Gungnir under two separate permits covering an area of 471.3 hectares. The properties are accessible year-round with good transportation and industrial infrastructure, including shipping facilities as there are a number of active mines in the area.

They collectively host 177 million pounds of nickel in inferred resources based on NI-43-101-compliant estimates by Gungnir in 2020

The deposits were discovered in the 1970s by the Swedish State Mining Property Commission and were subsequently held by Outokumpu Mining.  Exploration included geophysical surveying, extensive drilling (35,000 metres), metallurgical test work as well as development of an exploration shaft and drifting on the 120-metre level at the Lappvattnet deposit and initial resource estimates for both deposits in 1987.

The deposits came open for staking following exploration work by North Atlantic Resources (NAN), a company owned by Lundin Mining Corp. [LUN-TSX; LUMI-Sweden], and Blackstone Ventures Inc., under an option agreement with NAN in 2006. Gungnir submitted applications to acquire both deposits in 2015.

The Lappvattnet and Rormyrberget deposits are both magmatic nickel sulphide accumulations with tectonic, structural, and geological similarities to documented nickel and copper mines. The Lappvattnet deposit is largely a massive sulphide body that dips steeply to the south and plunges shallowly eastward.

Mineralization at Rormyrberget consists of both massive sulphide and wider disseminated zones.

Lappvattnet contains an inferred resource of 780,000 tonnes of grade 1.35% nickel or 231 million pounds of nickel. Rormyrberget hosts an inferred resource of 36.8 million tonnes of grade 0.19% nickel or 154 million pounds.

Drilling continues with tighter spaced holes at the shallow western part of the Lappvattnet deposit, with a current plan of 15 drill holes covering a strike length of approximately 140 metres.
