Fra før vet vi at REC og det amerikanske Forsvarsdepartementet har vært i samtaler rundt silisium i batterier. Skal prøve å finne linken senere, mener det var noe TT snakket om under en Q-rapport.

Uansett, dagens nyhet:

Army Recharges Conformal Wearable Battery Design

Project Convergence will test a new battery design for IVAS.

During the U.S. Army’s Project Convergence 2021 experiment scheduled for October, researchers will assess silicon anode cells for its Conformal Wearable Battery to be used with the Integrated Visual Augmentation System (IVAS) and the Nett Warrior system. The batteries double the power, allowing those systems to run much longer without increasing size and weight. Ultimately, the new cells could be used in a wide range of batteries for the military and commercial sectors, including those used to power tactical radios, electric cars and cellphones.

Enovix Set to Go Public Through a SPAC in Deal Valued at $1.1 Billion

Battery maker is building a factory in Fremont, Calif., to make batteries for wearable gadgets starting this year

Battery maker Enovix Corp. is poised to go public using a blank-check company in a deal valued at $1.1 billion, benefiting from investor enthusiasm for technology to improve battery performance as the world races toward electric vehicles.

Enovix said on Monday it raised $405 million through a merger with a special-purpose acquisition company, or SPAC, and associated private investment.

The company is building its first commercial factory, which will be ready to produce silicon lithium-ion batteries for customers later this year. The small-scale plant in Fremont, Calif., will make batteries for smaller devices such as radios and smartwatches. Enovix is scouting a location for a second factory that will also build batteries for smartphones, and aims to start selling batteries for electric vehicles after 2025.

Kommmentar: Batterier til wearables og andre gadgets trenger ikke samme produksjonskapasitet som til kjøretøy. En "smal scale plant" funker i Freemont, men neste steget opp må de flytte dit silanet kommer fra.

Jeg tror vi skal følge litt med på Enovix, det kan godt hende det blir ML neste.

NEO er ute med ny, meget lovende pressemelding om sine anoder. Rene silisiumanoder, som brytes ned under 25% etter 1000 sykluser!

Significant Results in Long-Term Cycling Ability and Mechanical Durability with NEO Battery’s 100% Silicon Anode Materials

Vancouver, British Columbia – March 29, 2021

Dr. Jong Hyeok Park, Director and Chair of the Scientific Advisory Board of NEO Battery Materials Ltd. (TSXV: NBM) (“NEO” or the “Company”), is pleased to announce that NEO has achieved breakthrough results in attaining a highly stable long-term cycling ability using 100% silicon (Si) anodes. The pure Si anode that does not contain graphite anode materials has been successful in demonstrating these results at automotive rates of charge and discharge for over 1000 cycles. With the help of NEO’s proprietary uniform nanocoating technology, the capacity decay, most importantly, was less than 25% after running 1000 cycles.

As Elon Musk, CEO of Tesla, said, incorporating silicon into the anode of a Li-ion battery has the potential to improve energy density by 20–40%, extending the maximum range of vehicles by 20%. However, it is not easy to make an anode from 100% silicon nanoparticles that lasts over just one hundred cycles of charge and discharge.

Dr. Park commented, “Our patented elastomer nanocoating layer which has both electronic and ionic conductivity is able to compensate the mechanical stress of the Si anode during a long-term cycling test. Our technology effectively scatters the stress from the Si anode, allowing commercial level areal capacity of >2.0 mAh/cm2.”

“Currently, several evaluations for NMC/Si full cells are underway on NEO Si anode materials. NEO is continuing to develop Si anode material modification technology to manufacture innovative anode materials for next generation lithium-ion batteries at a low and scalable cost,” added Dr. Park.

Tesla has been running a pilot factory for the new battery cell in Fremont where CEO Elon Musk has been guiding reaching a production capacity of 10 GWh by the end of 2021.

Today, with the release of its Q2 2021 financial results, Tesla released a rare update about its progress toward that goal:

We have successfully validated performance and lifetime of our 4680 cells produced at our Kato facility in California. We are nearing the end of manufacturing validation at Kato: field quality and yield are at viable levels and our focus is now on improving the 10% of manufacturing processes that currently bottleneck production output. While substantial progress has been made, we still have work ahead of us before we can achieve volume production. Internal crash testing of our structural pack architecture with a single-piece front casting has been successful.

In short, Tesla managed to get some progress done, but they still have more work to do before achieving any volume production.
