Teknologi - silisiumanoder og RECSI
Silisiumanoder kan bli en vesentlig del av vekstområde til RECSI og det er svært relevant å vite hvilke teknologi som krever silangass fra RECSI og hvilke som ikke gjør det. Lenken under gir en god innføring i de teknologiske løpene som nå retter seg inn mot neste generasjons EV og konsumerbatterier. Det er mange selskaper som nå konkurrere om de beste produksjonsløsninger, så det gjelder å følge med i svingene framover. Det positive er at det nå ser ut til at det er nokså lik teknologi som framstår som best, med felles nevner silangass i en eller annen form, noe som er eksepsjonelt med tanke på hva RECSI plutselig vil kunne bli i framtiden.

Beskrivelsen som er sakset ut under for dem som ikke orker lese hele (anbefales) er Sila Nanotechnologies sin teknologi så vidt jeg kan se da den er basert på referansen til publikasjon av Gleb Yushin - Co-Founder & CTO - Sila Nanotechnologies. Dette høres forøvrig veldig likt ut som Group 14 sin teknologi som skal benyttes i Moses Lake:
Gas-phase chemical vapor deposition is used to grow silicon and carbon layers, using precursors such as silane (SiH4) and propylene (C3H6). Gas-phase processing techniques (1) can be precisely tuned by controlling time–temperature combination, (2) can achieve highly conformal coatings when operated in a surface reaction limited regime, and (3) avoid the use of solvents which are often difficult and expensive to dispose of. While gas-phase precursors for carbon are generally inexpensive and readily available, silane requires special handling due to its pyrophoric nature and is expensive (NREL reports a cost of $184 per kg for 6 N silane, corresponding to $210 per kg of silicon31). Therefore while it is possible to realize conformal silicon coatings even on highly porous materials by operating in a surface reaction limited regime (i.e. at low-to-moderate CVD temperature), this may prevent the full utilization of a costly precursor. The authors in ref. 12 do not discuss the silane utilization efficiency for their synthesis process.

Så jobber Toyota, Nissan etc. med solide state batterier. Får de dette til innen 2025 så har de ett veldig godt kort på hånden. Dette er meget solide batterier og sikre. Ulempen med disse er at de bruker Lithium som er vanskelig å få tak i og prisene øker. Dvs at solid state batterier ikke er billige.
Mye skal skje innen 2025. Det blir spennende å se hvem som blir størst og hvilket batteri som blir det beste. Det er ikke tvil om at REC blir en del av silikon batteriene.

Det er knall. De også skal ha fabrikk i Sverige like ved Northvolt.. Lurer på hvor de skal få silan fra?.
Blir det å kjøpe silikon anoder fra G14 eller Sila Nano?
Eller vil det settes opp en fabrikk i Sverige eller andre steder i Europa? Lov å drømme om det.

Marelli & Fraunhofer develop motorsport power module
Fraunhofer IZM and the Italian automotive supplier Marelli have developed a power module for electrified traction applications in motorsport. The all-silicon carbide-based module, called EDI, is said to enable higher conversion efficiencies and to be smaller and lighter.
The Fraunhofer Institute for Reliability and Microintegration IZM says the name EDI stands for ‘Enhanced Direct-cooling Inverter’ and that the module was suitable for “high-performance electric drives”. Simultaneously, the partners say the technology will probably also find its way into road vehicles later on. “At Marelli Motorsport, our mission is to promote technological advances that can make the difference above all on the racetrack while enabling next-generation technologies for the road vehicles of tomorrow,” says Riccardo De Filippi, Senior Vice President and CEO of Marelli Motorsport.
The use of silicon carbide (SiC) is not a novelty in itself; suppliers such as ZF or Delphi also use SiC semiconductors in 800-volt components for production cars. Silicon carbide enables faster and more efficient circuits compared to semiconductors based on pure silicon.
The most innovative aspect of the Marelli-Fraunhofer development is that it does not require a base plate thanks to an “innovative structural design”, which is said to “drastically reduce” the thermal resistance between the SiC components and the cooling fluid. The partners say that the result is an extremely compact power stage that can take advantage of the efficiency benefits of silicon carbide and allow for more flexibility in packaging and cooling systems in terms of design.
Fraunhofer IZM says that compared to other silicon-based structures of the same power, the new technology enables a conversion efficiency of up to 99.5 per cent, reduces weight and size by half and has 50 per cent higher heat dissipation into the cooling system.
The EDI is currently being manufactured in a cleanroom at the Marelli plant in Corbetta, Italy. According to Fraunhofer IZM, the component has already undergone a series of reliability tests for motorsport application profiles. Whether and when Marelli is planning such a SiC power module for road vehicles is not yet clear.
At the end of November 2020, Marelli announced its intention to assemble electric drives in Cologne from 2021. In Cologne-Niehl, not far from the Ford plants, a production line for electric drives is to be installed on 18,000 square metres in the first half of the year. The Marelli Group was only formed in 2019 from the merger of the Italian supplier Magneti-Marelli (that used to belong to Fiat-Chrysler) and the Japanese company Calsonic Kansei (with roots in Nissan).

Vedrørende silisium vs Litsium som anode materiale:
Fra Wall Street Journal 10 mars 2021
Northvolt’s acquisition of Cuberg also highlights that the battle for brains is going to be one of the biggest challenges for car makers and their battery suppliers as the demand for developers and new battery technology intensifies.
“In the battery industry, there is going to be a war over competences,” said Mr. Carlsson, adding that Cuberg doesn’t yet have the “total secret formula” Northvolt needs. “But they are a bridge in our road map to get us from where we are today to where we need to be in 2030.”
Så det at Northvolt kjøpte opp Cuberg handler ikke bare om at de tror Lithium anoder er fremtiden for batterier, det er også en måte å sikre seg tilgang til mennesker med kompetanse på batterier.
Et annet perspektiv er at bruk av litsium som anode materiale til kommersielt bruk ser ut til å ligge noen år frem i tid ettersom de snakker om «ambisjoner» om å ha noe klart i 2025...
«Cuberg’s batteries, based on its breakthrough electrolyte technology for lithium metal anode, are optimally designed for commercialization. Validated by trusted third parties, the cells deliver more than 70 percent increased range and capacity versus comparable lithium-ion cells designed for high-rate electric aviation applications. Building on this foundation, Northvolt and Cuberg will mature its automotive and industrial product portfolio with the ambition to industrialize cells in 2025 that exceed 1,000 Wh/L, while meeting the full spectrum of automotive customer requirements.
“Critically, Cuberg’s technology addresses the biggest challenge with emerging battery technologies, which is effective manufacturing scale-up. Cuberg has already demonstrated compatibility of its technology with the existing lithium-ion manufacturing ecosystem, which minimizes time to market and enables rapid commercial deployment in the electromobility market. The new technology will be deployed at scale in electromobility markets within three years, beginning with electric aviation.”
Group 14 som har børsmeldt sammarbeid med REC og som skal ligge vegg i vegg ved ML skriver i desember at de begynner å levere batterier med silisium anoder i 2021!
Group14's breakthrough lithium-silicon technology, SCC55™, promises to deliver dramatically more energy density per volume to meet the increasing global demand for high-performing lithium-ion-based storage. Group14 has begun ramping up its pilot production and plans to supply its first commercial customers in consumer electronics in 1Q21, with more to follow in other markets.
For meg ser det derfor ut til at silisium anoder har et teknologisk forsprang i forhold til litsium anoder og vil begynne å produseres først. Etterhvert kommer kanskje litsium anoder i 2025 eller senere og batterier vil da kanskje benytte begge teknologiene.
Hvorvidt en av anode materialene vil dominere tilslutt eller om det finnes fordeler og ulemper ved begge materialene som gjør at begge har livets rett aner jeg ikke (og ingen andre heller pr dd).

SMIC vil bygge en 2,35 mia. dollar dyr fabrik til at producere chips
WOODINVILLE, Wash., March 19, 2021 /PRNewswire/ -- Group14 Technologies, a global provider of silicon-carbon composite materials for lithium-ion markets, announced the company's international expansion with new offices in Yokohama, Japan and Seoul, South Korea. With the vast array of major consumer electronics and electric mobility players in APAC, the international expansion positions Group14 as a key global supplier to meet increasing customer demand for high-performing lithium-silicon battery materials.
"With Asia's dominance of the EV battery market, the decision to expand our presence internationally was an easy one for the team," said Grant Ray, Vice President of Marketing at Group14 Technologies. "This move allows us to strengthen the relationship with our existing APAC customers and acquire new customers in the largest and fastest growing markets for consumer electronics and EVs."
A leading provider of anode battery materials, Group14's breakthrough lithium-silicon technology, SCC55™, promises to deliver dramatically more energy density per volume to meet the increasing global demand for high-performing lithium-ion-based storage. The company is rapidly expanding, adding nearly 20 team members in the last three months, and is expected to grow the team further as the company ramps up production this year.
Group14 has several footprints in Asia; South Korea's SK materials led the company's Series B while earlier financing was led by global manufacturing leaders including Amperex Technology Limited (ATL), the world's largest producer of lithium-ion batteries for consumer electronics headquartered in China, and Showa Denko, the largest producer of graphite, headquartered in Japan.
"Higher-performing battery performance is the key to unlocking the electrification of everything from motorcycles to lightweight trucks," said Rick Luebbe, CEO of Group14 Technologies. "Once we enable cost-parity with internal combustion engines globally, we will see rapid acceleration of electric vehicle adoption in the years to come."

Det er ikke krydderet som sørger for investeringsrammen her, men renheten på poteten.
Det er mye jordsmonn i en potet, og de har funnet en metode for å fremstille potet med 11N renhet.
Denne ekstremt rene potetmassen blir smeltet om i en potet-trekker og man lager en monokrystallinsk potetblokk, denne blir skåret opp til wafer (chips),og så kommer krydderet på banen.
Ja…jeg er en nerd.

Kanskje det er nevnt tidligere, men jeg så igjennom Teknas, AFK selskapet som hentet penger i dag, presentasjon. Og på side 26-28 skriver de om silisium og batteri, og oppgir at deres prosess bruker silan, så nok en potensiell kunde.
"Three methods for manufacturing Silicon
• Silane (Tekna process): Expected to become the most used Si source material
• Milling and crushing: Dominating method, but battery performance has reached a
physical limit with this method
• Chemical process (Trichlorosilane): Will continue to be a limited Si source, due to the
difficulty in handling and limited availability"
