REC 29.10.2018 kl 08:39 119937

Siden dette kan bli et spennende område for REC i nær fremtid, kan det jo være interessant å holde seg oppdatert på nyheter herfra.

Kan jo starte med LG Chem:
LG Chem invests in Enevate; silicon-dominant Li-ion battery technology

Enevate Corporation, developer of a silicon-dominant composite anode material and high energy density batteries (earlier post), announced that LG Chem has participated in Enevate’s recent funding.

Introduced in November 2017, Enevate’s HD-Energy Technology for EVs enables Lithium-ion (Li-ion) cells with up to 50% higher capacity than conventional graphite cells. The cells can be charged to 75% capacity in five minutes. They can also safely charge and discharge down to -40°C and capture more energy during regenerative braking, extending their range in cold climates.

Enevate’s HD-Energy Technology is a self-standing, silicon-dominant composite anode with more than 70% silicon. The conductive, silicon-dominant composite film anode is essentially 100% active material that can store lithium and has a high electrical conductivity.


Detta verkar vara ett projekt i Norge: – IFE’s contribution is to make the silicon-carbon composite anode which is one of the two competing anodes that will be developed into the final cell. One of the two will be chosen at a certain milestone, says Hanne Flåten Andersen, Department Head at the Batteries unit at IFE. The competing anode will be developed by The French Alternative Energies and Atomic Energy Commission (CEA). https://ife.no/en/ife-partner-in-eu-project-for-next-generation-batteries/

Toyota og Panasonic går i JV for videreutvikling av Li-ion batterier. Vår venn John B. Goodenough og vennene hans har en finger med i spillet, det lukter nanograde FBR lang vei :-)
The batteries will specifically be prismatic lithium-ion batteries. The utility of lithium-ion batteries used in so many different technologies was recently confirmed by the awarding of the Nobel Prize in Chemistry to three figures crucial to the technology’s development.

Jeg tror det skyldes at Elkem har et substandard produkt i forhold til REC, de kan få til små størrelse men de får ikke til porøsiteten :)
Det kan være derfor TT sitter på MosesLake og tar imot de 30 største batterikundene, mens Elkem er på salgstokt :)

Ingen av de andre klarer å få til naturlige, porøse nanopartikler i de mengder som FBR kan gi :)

Når det gjelder DowSil.. så har de spesialisert seg på organisk silan, dvs silan som har en eller flere Hydrogen/Klor byttet ut med en lengre eller kortere hydrokarbonkjede :) Disse er veldig kostbare å produsere (tåler ikke så høye temperaturer) og helt utenkelig for EV-industrien. Jeg gjetter det finnes bruksområder for organisk SI-nanopartikler innen medisinen feks pacemakere eller strømforsyning for sensor eller sonder i pasienter :)

Europe Pushes on With Gigafactory Plan to Rival Tesla

Brian Parkin

February 7, 2020, 6:08 PM GMT+1

Germany and France set out a blueprint for a giant battery factory, advancing Europe’s 5 billion euro ($5.5 billion) bid to rival the capacity of Tesla Inc. China to supply the key part for electric vehicles.

The announcement at Germany’s Economy and Energy Ministry units underscores determination by European Union nations to catch up with Asian competitors that dominate battery making. Battery cells and add-on electronic devices and software make up as much as half the value of EVs.

The facility at Groupe PSA-Opel’s site in Kaiserslautern involves Total SA’s Saft Groupe in a plant that will be named the Automotive Cell Co. The plant will cost about 2 billion euros and will complement a French factory in the Hauts de France region.

Germany and France “want to build the best and most sustainable batteries” in Europe, Economy and Energy Minister Peter Altmaier said in a statement from Berlin on Friday. “I’m convinced that battery cells made in Kaiserslautern will set new standards in their CO2 footprint.”

Together, the factories will cost about 5 billion euros add production capacity to 48 gigawatt-hours of batteries.

Backed by the European Commission, France and Germany dangled subsidies to win over sketics within the auto industry about investing in the technology. While German companies such as Volkswagen AG and BMW AG dominate car manufacturing in Europe, they’ve allowed Asian companies and Tesla to take the lead on making batteries.

Contemporary Amperex Technology Co., or CATL, and BYD Co. Ltd. of China are among the leaders in making lithium-ion battery cells, while Tesla has invested in a string of “gigafactories” to supply its luxury electric cars.

The European governments also aim to incorporate tighter emission standards in production and recycling stipulations, which may create hurdles for Asian products. European battery cells “won’t be comparable with cheap Chinese products,” Altmaier said last year.

The Kaiserslautern factory will be up and running by 2024 and employ 2000 people, Opel’s management board head Michael Lohscheller said. The German and French cell production sites may serve 10% to 15% of demand in Europe, said Altmaier. Germany alone is targeting 7 million to 10 million electric cars on its roads by 2030.

Some 13.8 million jobs representing 6.1% of the workforce may be linked to auto manufacturing in the EU. The market for battery cells may be worth as much as 250 billion euros by mid-decade, the EU Commission said.

Still, the competition from Asia is likely to be tough.

CATL has gained a foothold in Germany in a factory in Thueringia state with a plant with 16 gigawatt-hours of capacity. In 2018, the Chinese company said it aims to be close to the market for for production sites of BMW AG, Volkswagen AG and Daimler AG.

LG Chem Ltd is building a battery cell gigafactory in Poland, close to Eastern German car production sites. Tesla Inc. said in November that it will open an electric car production site on the outskirts of Berlin, and Northvolt AB is building a plant in Sweden.


Godt nytt det der. Spesielt med tanke på Kinas kull drevne Siemens reaktorer

MOSES LAKE - Moses Lake’s REC Silicon halts employee travel to sister plant in China until further notice

Business trips to China have come to a halt for Moses Lake’s polysilicon manufacturer. REC Silicon’s sister plant, Tian REC, makes polysilicon in Yulin, Shaanxi, China.

Tian REC is located 767 miles north of Wuhan, the epicenter of the deadly coronavirus outbreak.

Moses Lake REC Silicon Vice President Chuck Sutton says a handful of Moses Lake employees cycle in and out from the Chinese factory, but someone from Grant County is usually present at Tian. Sutton says the company is confident that everyone from the Moses Lake plant left in advance of the outbreak several weeks ago.

REC’s decision to get employees out of China was timely in the sense that now all provinces of China have confirmed cases of coronavirus. Sutton says all REC Silicon employees will not travel to China “until the situation stabilizes.”

Sutton added that the plant contacted the Grant County Health District for advice on what it should do with employees who were still present in the Asian country and were reportedly advised to offer an option of return.

REC Silicon has not required anyone to undergo medical testing since returning from China explaining that all had returned prior to the outbreak

Konkurransen om å produsere nanopulveret er i gang. REC bør ikke sove i timen nå...


Northvolt batterier är grundat av en person som tidigare jobbade nära Elon Musk. Det är väl sannolikt att Northvolt kommer att använda kisel i sina anoder.
Går det att undersöka?
16.02.2020 kl 09:43 4964

Det ser ut som Northvolts strategi er å effektivisere produksjonen av eksisterende teknologi, og de fokuserer på katoden fremfor anoden, da de mener katoden vil forbli den samme lenge, mens anoden vil stadig utvikle seg. Et race som er kostbart å være med på, fremfor å effektivisere allerede eksisterende teknologier.

«Cathode is expected to be a very long-lasting part of the equation, and what you want to do is invest in assets with a very high longevity to make sure the money you are deploying will continue to work for a long time.»

By comparison, the executive said that Northvolt would not, at least initially, compete in terms of technology, but rather in the production process through its vertical integration.

“We are not trying to be the first to introduce solid-state batteries, someone will do it probably before us — we want to do very well and very efficiently what others are planning to do,” he said.

Det vi ser er starten på et oppkjøp av større eierandeler i REC. Det kommer nyheter om batteri-samarbeid om ikke lenge.

Det er kort vei til 10 kroner. Aksjen har startet stigningen på vei dit.

«It is a race among the batteri makers to get more and more Silicon in» .. more and more👌

«Battery bonanza»

Og TT prøvde under Q4 pres med dårlig skjult pokerfjes å fremstå som om han hadde lite peiling på batteri utviklinga..

Ja, men denne er jo egentlig i større grad en god reklame for REC Silicons konkurrent Elkem ... ! De har god innsikt i silisiumnitrid-prosesser, og kanksje det er nettopp dette som Tesla kjøper derfra. Basert på https://www.elkem.com/globalassets/silicon-materials/documents/silicon/2019-01-11-silgrain-supreme-microncut.pdf ?

Og nei, dessverre, TT har nok ikke peiling på batteriteknologi. Virker opphengt i PV-bransjen hvor han smertelig har sine hovederfaring fra. Kanskje yngre krefter med mer vidsyn bør søke jobben?

Hmm ....

Jeg bør vel også tilføye at en av måtene elektronikkindustrien lager silisiumnitritlag på, er ved å få silan og ammoniakk til å reagere sammen ... Så kan overskuddet av hydrogen gå til de få hydrogenbilene som ruller på veiene. ;-)

Men vi vet vel ennå ikke med full sikkerhet at det er den retninga batteriteknologien tar.
18.02.2020 kl 13:04 3969

Alt tyder på at silisiumbatteriene kommer, de første produsentene har allerede annonsert at de er klare for masseproduksjon.

Men hvor langt bak er solid state? Ulike elbilprodusenter satser på den ene eller andre, og begge leire hevder at batteriene vil rulles ut på veien i 2024/25.

Mitt bet er at de vil leve side om side en god stund. Allerede eksisterende litium-ion-fabrikker lager silisiumbatterier, nye fabrikker bygges med solid state-kapasitet. Dersom solid state faktisk er billigere å produsere, da.

Vi får se.

Enevate Battery Technology Advances Next Generation Power Cells for the Power Tool Market
Technology Offers Long Runtime with High Energy Density and Low Temperature Performance

February 18, 2020 03:00 AM Pacific Standard Time
IRVINE, Calif.--(BUSINESS WIRE)--Enevate, a pioneer in advanced silicon-dominant lithium-ion (Li-ion) battery technology capable of high energy density and fast charging for electric vehicles (EV), announced that it has applied its innovative battery solutions to advanced power cells for the power tool market and other high power applications. For example, in a 21700 cylindrical power cell, 5.9Ah can be achieved utilizing Enevate technology, far exceeding the capacity of other power cells in the market, which today averages 4Ah. Enevate developed the power cell to be capable of high energy density, low temperature operation, and both high discharge and charge rates, allowing very short recharge times of depleted batteries which power cells today cannot achieve.

“Power tool users, especially in areas such as the home, industrial, and business construction, need portable power tools with longer battery runtimes and the ability to work in cold temperatures.”

“Battery powered power tools are an important and large market segment, and Enevate’s battery technology is extremely well-suited to serve this market,” said Dr. Benjamin Park, Enevate Founder and Chief Technology Officer. “Power tool users, especially in areas such as the home, industrial, and business construction, need portable power tools with longer battery runtimes and the ability to work in cold temperatures.”

Dr. Park added: “The Li-ion battery technology we’ve developed is especially well-suited for fast discharge and longer runtimes through increased energy density, enabling power tool users more and longer productive work time between charges. We have developed cylindrical cell designs that use the fundamental nature of our inexpensive and scalable silicon-dominant battery chemistry.”

He noted that opportunities to serve the power tool market will happen sooner – in the next year or two – than the longer-lead electrical vehicle (EV) battery market, in which Enevate is preparing its pioneering technology for 2024-2025 EV model years.

Enevate’s power cell has been tested at up to 10C sustained discharge rates. Also, power tools must have the ability to operate in cold climates outdoors; Enevate’s power tool cell is able to operate down to -20degC and has excellent low temperature cycle life.

Enevate's XFC-Energy™ battery technology can charge 75 percent of the total cell capacity in five minutes at 10C charge rates. Typical power cells today can only charge at about one-sixth of the rate of Enevate cells, resulting in a charge time that is six times longer.

The vast majority of the power cells on the market are cylindrical cells, which can be supported by Enevate technology. Power cells using Enevate’s technology can be wound as cylindrical cells, or made as pouch or prismatic can cells.

Hva synes den utmerkede kommentator grabein om Elkem sine produkter?
23.02.2020 kl 08:28 3245

Jeg har faktisk ikke satt meg i Elkem, siden jeg er såpass fastlåst her med forholdsvis høyt snitt. Men Elkem burde vel også kunne nyte godt av batterirevolusjonen.

Elkem er forholdsvis billig nå , de kjører på med gode utbytter ( kinesiske bluestar storeier) . Bør kunne gå 50-70 prosent neste 2 år . Rec har ikkje utbytte og kommer vel ikkje med det på mange år , men eg meiner vel potensialet på aksjekursen nå er bedre enn elkem . Likevel , elkem og norsk Hydro er en av mine trygge favoritter med utbytte.

Er det noen som har sjekket ut Williams Advanced Engineering som nå i en årekke har vært hoffleverandør til Formel E.... Regner med at de ligger helt i front ang. batterier??

Regner ikke med at de utvikler selve batteri teknologien, men de er en typisk samarbeidspartner for selskaper som vil utvikle og teste ut.. Ser de samarbeider med Panasonic (Jaguar Racing Team)

Williams Advanced Engineering was the sole supplier of the battery system for the entire Formula E grid since the fully-electric FIA racing series began in 2014 to the end of season 4 in 2018. The company's battery expertise originated from Formula One, following the introduction of KERS – including new batteries and battery management systems – into the sport in 2009. The challenge has been significant. The Formula E battery has to propel cars to speeds of up to 225kph, yet still be practical in terms of safety, aerodynamics, range and recharging times.

And safety is at its core; it is the first lithium-ion battery to have passed stringent FIA crash testing regulations and met stringent air safety regulations in order to be transported around the world to support the global race calendar.

Over four seasons, there have been only two on-track failures and the equivalent of more than 1,000 cars have raced using the battery since the championship started, representing a success rate of more than 99.5 percent. The total distance travelled by Williams-supplied Formula E batteries is 240,000miles – the same as a trip from the Earth to the Moon.

In 2018, Williams Advanced Engineering received the Queen's Award for Enterprise in Innovation for its ability to design, develop and deliver the batteries for all Formula E cars racing in the championship while ensuring the successful transfer of that knowledge to road cars and other forms of sustainable transport outside of the all-electric racing series. Also in 2018 the company was named as the sole supplier of batteries for the electrification of the World Rallycross Championship in 2020.

Litt googling, og det virker som Williams forsker på saltbatterier (Na-ion). Problemet der virker å være å finne et passende anodemateriale. Man kan ikke bruke grafitt, og jeg har ikke klart å finne en match på silisium heller (har bare googlet noen minutter). Derimot driver man og forsker på tinnoksid, antimon og alskens andre materialer til anoden.


Takker for den grabein, hmm, hadde vært flott om du fant en link her til silisium...

Det ser jo spennende ut. Men, som du sa, på forskningsstadiet. Hvor det finnes hundrevis av konsepter.

Når det er sagt, Williams er jo pionerer og lager ting som funker. Hvis silisiumbatteriene tar av, så vil det jo være rart om de ikke skal kjøre på. Spesielt dersom batteriene er lettere og lader/utlader raskere enn nåværende litium-ion-batterier. Viktig på racerbanen!
