Nyheter innen silisiumbatterier

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.

BioSolar Begins Production and Testing of Lithium-ion Battery Prototype Incorporating Its Performance Boosting Technology

Company will use the new high density 21700 battery format for its prototypes

SANTA CLARITA, Calif., April 09, 2019 (GLOBE NEWSWIRE) -- BioSolar, Inc. (OTCQB:BSRC) (“BioSolar” or the “Company”), a developer of breakthrough energy storage technology and materials, today announced that its technology partner has commenced production and testing of the first batch of commercial grade prototype lithium-ion cells for power tool application in the new 21700 cell format being adopted by a number of high-growth industries including power tools, consumer electronics and electric vehicles.

The 21700 cell format is one many believe can increase battery density, thus positively impacting overall power. In February, automotive manufacturer Nikola teased its new line of all electric truck models, citing in a tweet its dependence on 21700 cells. In power home technology, Milwaukee Tool announced two new cordless tool battery packs, including a high output segment that carry 21700 cells, up from the 18650 format in pre-existing series.

As disclosed in a previous announcement, BioSolar began applying its performance boosting additive technology to the emerging category of silicon anode lithium-ion battery cells. As the cell develops and hopefully demonstrates commercial viability in a power tool application, BioSolar believes its technology can also generate interest from a broader audience of battery manufacturers and end users alike.

“As we progress with the development of our commercial grade prototype batteries, it is essential for us to communicate the process to our partners, potential customers and shareholders,” said Dr. David Lee, CEO of BioSolar. “We anticipate our performance boosting technology will show enough progress in these prototypes to transition BioSolar from a technology development company into one with commercially viable technologies suitable for use in a number of high-growth industries.”

About BioSolar, Inc.

Over the last decade, a few Silicon Valley startups have been working to solve this problem. For example, Sila Nano’s approach is to encase silicon atoms inside a nano-sized shell with lots of empty room inside. That way, the SEI is formed on the outside of the shell and the expansion of silicon atoms happens inside it without shattering the SEI after each charge-discharge cycle. The company, valued at $350 million, says its technology will power devices as soon as 2020.

Enovix, on the other hand, applies a special manufacturing technique to put a 100% silicon anode under enormous physical pressure, forcing it to absorb fewer lithium ion and thus restricting the expansion of the anode and preventing the SEI from breaking. The company has investments from Intel and Qualcomm, and it also expects to have its batteries in devices by 2020.

These compromises mean the silicon anode can’t reach its theoretical high energy density. However, both companies say their anodes perform better than a graphite anode. Third parties are currently testing both firms’ batteries.

Daimler (Mercedes Benz, Chrysler) tar størsteparten av 170 millioner dollar investering i produsent av silisiumanoder (Sila Nanotechnologies)! Vi vet fra før at BMW allerede er kunde. Det skjer nå! Allerede på slutten av 2019 får vi første produksjonsbatch av batteriene fra Sila. Derfra satser man på større skala. Alle mann til silanpumpene!

"Daimler has led the latest US$170 million round of funding for anode materials firm Sila Nanotechnologies. Total backing for the California-based firm now stands at US$295 million.

Other investors in the latest round included Bessemer Venture Partners and Siemens Next27.

The company’s silicon-based anodes can replace graphite without any change to manufacturing infrastructure. It claims an average improvement of 20% dependant on the associated battery chemistry. Sila’s anodes can be used an assortment of Lithium chemistries including Nickel Manganese Cobalt (NMC), Lithium Iron Phosphate (LFP), Lithium Cobolt Oxide (LCO) and Lithium Nickel Cobalt Aluminium Oxide (NCA).

Alex Nediger, Daimler’s director of cooperation and innovation management will join the Sila board as will former GE CEO Jeff Immelt.

“Advancements in lithium-ion batteries have become increasingly limited, and we are fighting for incremental improvements,” said Immelt. “I’ve seen first-hand that this is a huge opportunity that is also incredibly hard to solve. The team at Sila Nano has not only created a breakthrough chemistry, but solved it in a way that is commercially viable at scale.”

Sila is targeting four markets and is ramping its production now with the consumer electronics its first target. It will then move onto producing for its partners in the electric vehicle space, BMW and Daimler. It lists grid storage and aviation as the other two pillars of its business.

“We’ve cracked the code on silicon thanks to eight years and 35,000 iterations developing our materials to improve battery storage capacity,” said Gene Berdichevsky, co-founder and CEO, Sila Nano. “Now we’re ready to bring this to market, and partners like Daimler and Jeff Immelt bring critical expertise and support as we enter this next phase and begin putting Sila inside the vehicles and devices people use every day.”

The competition for creating better lithium batteries is increasing. 24M, a startup spun out of the labs at MIT, recently touted gains it has made in creating a platform for manufacturing semi-solid lithium-ion battery cells using compositionally distinct catholytes and anolytes, kept apart by an ionically conductive, non-permeable separator. Designing the technology and processes so that they could be adapted for both nickel manganese cobalt (NMC) cells commonly used in EVs as well as LFP (lithium iron phosphate) more typically used for stationary storage - particularly at residential scale - 24M claimed it can reach energy densities exceeding 350Wh per kg, with plans to open a small production line by the end of this year."

👌 NICE,,

Nå strammer strikket seg for shortsene nok en gang, st REC blir leverandør innen Batteri teknologien fremover er 100% sikkert.
Fest setebeltene, strikket ryker når som helst 😉
17.04.2019 kl 00:37 2990

Hvorfor er det sikkert at Rec kommer til å levere inn til batteri industrien? Her trengs det nærmere forklaring eller er jeg for langt ned i cognac glasset?


Rec ledelsen har allerede uttalt at de har fått henvendelser fra batteri produsenter, forbruket til dette bruket kommer til å ekspandere kolossalt fremover, ( det snakkes løst om 5-12 kg sil PR EV, og flere titalls millioner biler PR år i tiden fremover, gir enorme muligheter for Rec, 👍
17.04.2019 kl 06:03 2897

Er ikke bare i EV dette kommer til å eksploderer. Batterier til lagring av fornybar energi er på full fart inn over alt.

Ja, Sil revolusjonerer akkurat nå «batteri»/ energi lagrings teknologien,,😉👍


Molten silicon just doesn't degrade like lithium does," says Bondarenko. "That's a chemical process, ours is simply phase-change with heat. In fact, it appears silicon even gets better at storing heat after each cycle. And if you do need to decommission a TED device, it's 100 percent recyclable. It simply doesn't create the environmental problems that lithium does."
17.04.2019 kl 08:30 2745

REC er verdens største produsent av silangass, nødvendig i produksjonen av silisiumanoder. Og når REC selv sier batteriprodusenter kommer til å bli en viktig del av deres kundegruppe, så har man all grunn til å høre etter.
17.04.2019 kl 08:43 2722

Har de egentlig sagt at batteriprodusenter blir en viktig kundegruppe. På meg virker TT veldig reservert. Men for all del, jeg ønsker du har rett👍
17.04.2019 kl 09:06 2667

Han var litt reservert sist gang, men det er likevel liten tvil her. TTs tidshorisont er for konservativ i mine øyne når han snakker om 3 år.

Tore Torvund, REC Silicon ASA - CEO & President [15]


Let's say we have several companies coming to Moses Lake to discuss the availability of silane gas. It's mainly the silane gas, which seems to be of interest to them. On the other hand, it is not a developed market yet. Let's say, we have heard that some Chinese companies are using about 6% silicon at the maximum in their anode today. There is major technological issues to be resolved. But more and more people says that we can, 2, 3 years now see an opportunity that there will be 50% to 60% silicon in the anode, which will then increase the capacity of a battery by some 30%. My position today has been that I have tremendous amount of silane when you need it. So come back when we can definitely sign a contract, but we are not going to be the battery expert. We are going to supply the material they need to make these batteries.
17.04.2019 kl 09:10 2657

Fra Q3 18:

"And there is only five companies able to deliver the quality, which is needed in the semiconductor market, and REC is one out of those companies. The new thing coming out is batteries. It has been approximately 20 companies now visiting REC in the U.S., talking about silicon into batteries. We don't know too much about, let's say, the technology and batteries. This is not our, let's say, competence. On the other hand, let's say, these companies they are talking about the batteries will become four times more efficient by using silicon instead of graphite in the anodes of the batteries.

The second thing is that already today 5,000 to 10,000 metric ton out of 400,000 metric ton is used in batteries by companies like Tesla, Samsung, Panasonic and LG, but the market could exceed within the next five years about 100,000 metric ton. And even here, in Norway, we see that there is a strong interest of using – R&D using silicon into the anodes of the batteries. The new thing is basically that both in the U.S. and in Europe, there is a very strong focus now to build a battery, let's say, business.

As you can see from the slide, China seems to be running, let's say, ahead of all others also on the battery side. They have done tremendous investments. They continue to do a lot of investments in batteries. China has basically what they call the 2025 mission. It is about renewables, it's about storage and it's about electric cars. And they do all the investments within these areas.

European car manufacturers, U.S. car manufacturers are very worried about that, let's say, when electric cars come, they don't have necessary supply of batteries and that's why if you remember – or you probably saw some days ago, EU put together a huge package to promote building battery competence in Europe and the same thing in the U.S. And when we now met with the USTR talking about what is important in terms of the trade war, batteries was really what they were focused on because they really want to keep kind of these industries, polysilicon industry, in the U.S. to support also development on the battery side.

This is not an important business to us as of today. But hopefully, within the next two to three years, this will be a very important part of our business as well. And the battery companies are particularly looking for silane and for granular because one of the important thing is that you use polysilicon, a very, very small sized polysilicon granular. That's what they are looking for."

Takk for interessant link. Det skjer mye og vi står helt klarr foran en aldri så liten energirevolusjon. Gleder meg til å kjøre elbil med rekkevidde 2000 km.
Kombinasjonen sol og batteri blir uslåelig.


At Rec blir en kommende gullgruve for aksjonærene , det begynner å bli virkeligere for hver dag som går.
Bare vent å se, tolmodighet her kommer lønne seg

Ha en fortsatt god påske

19.04.2019 kl 18:59 1946

Håper du mener 60 kr, ettersom vi nesten helt sikkert får en 10:1 spleis ;) Men ja, spennende, og spesielt siden vi allerede nå vil begynne å se økt mengde sil i anodene. Husk at Tesla lover at den nye Roadster i 2020 får 200 kWh, dobbelt av dagens versting. Hvordan skal de klare det med dagens teknologi? Man kan ikke bare doble str på batteriet, da blir den altfor tung, og man får neppe plass i det lille, snertne formatet. Jeg tipper Tesla har en ny anode på gang, med ytterligere økt mengde silisium.

Vi får se!

Scaling up the SiNANOde production from 10 to 100 tons annually

PALO ALTO, California: OneD Material announces the issuance on March 26th of the new US Patent No. 10,243,207. The patent discloses novel industrial-scale manufacturing processes to produce SiNANOde anode material at volume and cost which are attractive to battery makers and their OEM customers.

Dr. Yimin Zhu, OneD's Chief Technology officer, is one of the three co-inventors.

For more than a decade, Dr. Zhu and his team have worked on new methods to grow silicon nanowires on graphite particles to increase the energy density of lithium ion batteries. Since 2010, OneD has produced growing quantities of SiNANOde and supplied several leading battery makers for extensive testing. More recently, this team has successfully perfected and optimized the manufacturing process to scale production of SiNANOde from today's 10 tons to over 100 tons capacity per year.

SiNANOde manufacturing process uses commercially available CVD furnaces to grow silicon nanowires directly onto the best commercially available graphite active materials using silane gas supplied already at scale to the semiconductor and solar industries. This unique combination enables the increase in SiNANOde production volumes by orders of magnitude at a very competitive cost.

In contrast to silicon oxides (SiOx) added to graphite anodes in some commercial batteries or newer silicon-graphite materials recently announced but yet not available in commercial quantities, SiNANOde anode materials provide a far superior drop-in solution to reach higher energy densities which has been already produced at tons-scale and is now ready to be produced at increasing industrial scale and attractive costs.

More details on the manufacturing process and the SiNANOde materials are available at OneD's website under the TECHNICAL SECTION.

Silisiumanoder fremstilles bl.a. med silangass ja. Derfor er alt av sil-batteriproduksjon av interesse. Dette kommer til å bli stort, potensielt på mye kortere sikt enn hva folk tror. Tipper at vi om 2 år fra nå ser på et helt annet marked.
20.04.2019 kl 14:22 1611

Ja, og i tillegg er dette veldig positivt for elektrolyseindustrien, Hydro og en mengde andre aktører.

Ser ikke helt hvordan dette er positivt for "hele elektrolyseindustrien", men har kanskje gått glipp av noe...?

Som en bekreftelse på at Sila Nano Inc benytter silangass som innsatsfaktor, kom jeg over følgende tekst fra deres utviklingsanlegg:

"The second really cool business related news is that a company called Sila Nanotechnologies is moving their battery related business to Alameda from Atlanta, Georgia. Recently they filed an application with the City of Alameda to build some sort of outdoor container to house nitrogen and to house silane which is another gas that I had to Google. Sila Nanotechnologies is looking to move their headquarters and lab space to Mariner Square.

Here’s what Sila Nanotechnologies does:
“Sila is developing a high-throughput technology for scalable synthesis of high-capacity nanostructured materials for Li-Ion EV batteries. The successful implementation of this technology will allow improvements in energy storage capacity of today’s best batteries at half the cost.""

Siden de store bilprodusenter allerede posisjonerer seg med oppkjøp, lurer jeg på om ikke ting kommer til å skje lenge før TT antydet.

25.04.2019 kl 14:48 1276

Ref ditt spørsmål : Virker snarere som du ikke vet hva elektrolyse er. Slå det opp, Johnny:)

Joda, jeg er godt kjent med hva elektrolyse er og hvordan det virker. Men jeg ser ikke riktig det du ser. Kan du ikke være vennlig å forklare hvordan dette er til fordel for denne industrien?
25.04.2019 kl 16:00 1174

De forsker på å bedre anodene...
25.04.2019 kl 17:17 1062

Flyers, du er på villspor her. Anoder i aluminiumsindustrien inneholder ikke silisium. Dette vil da bare bli ett fremmedstoff i smeltebadet som fortrinnsvis inneholder Al - aluminium.
25.04.2019 kl 20:54 930

Ok, og da mener du at anodene de bruker et laget av aluminium, eller?
25.04.2019 kl 20:57 927

Anodene som brukes veier 1000 kg og spises raskt opp under elektrolysen. Nye anoder kreves hele tiden. Mulig det er rett at silisium ikke kan brukes.

Global Graphene Group launches a graphene-silicon Li-Ion battery anode material

Global Graphene Group, and its subsidiary Angstron Energy (AEC) has developed a new graphene/silicon composite anode material (GCA-II-N) which can increase the capacity of Li-Ion batteries while reducing the battery's size and weight. AEC current market focus is on electronic bikes and consumer electronics, but is also working with Tier-1 electric cars and trucks makers


AEC has already commercialized the material, and the company has a production capacity (at its Dayton, Ohio plant) of 50 tons/per year. AEC is expanding the plant and by 2020 will have a capacity of 1,000 tons/year (in Ohio and also in its Asia-based production site).

AEC says that the new anode material boasts 8X the specific capacity of current graphite anode materials. Coupled with a current cathode material, it can enhance the battery's capacity by 35%, and if coupled with an emerging cathode could increase the capacity by 100%.
