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.

Kan det være at REC er i samtaler med dette selskapet og at det kommer sensajonelle nyheter tidlig i 2020?

Nei. Du må forstå hvordan XNRGI bruker Si til å produsere batterier. Og så må du forstå hva REC tilbyr, og som batteriprodusentene angivelig etterspør hos REC. Det finner du ut ved å lese Q2-presentasjonen s. 15-16 + 24-25. Da forstår du også REC's egne oppgitte estimater for salg av Si til (også) batteriproduksjon for 2020. Det er bare å lese tallene fra grafene. Noen sensasjonelle nyheter venter vi ikke på.

Takk takk Trier,

Meget spennende. Det eneste som er sikkert er at silisium er fremtiden når det gjelder batterier. Rimelig sikker på at ML er oppe og går igjen i løpet av 2020. Stå på! Takk for at du deler.

Porous silicon layers for more efficient lithium-ion batteries

06-Sep-2019

The Fraunhofer FEP has developed coating processes for industry for several years. Recently in the project PoSiBat, Fraunhofer FEP scientists were able to develop a non-toxic and efficient manufacturing process for porous silicon layers. The results of the recently completed project will be presented at the Thin Film Technology for Energy Systems workshop at V 2019 and at the Fraunhofer FEP booth No. 22 (October 8 –10, 2019, in Dresden, Germany).

...

Dr. Stefan Saager from Fraunhofer FEP explains the innovation: "We have developed a process in which silicon and zinc are simultaneously deposited on metal substrates. By applying a subsequent heat treatment, the zinc re-evaporates from the layer and pores are generated at the locations of former zinc grains. The porous structure in the silicon provides adequate space for its expansion during charging process and thus capacity fade is minimized. The porous structure can be manipulated and optimized to the specific battery requirements by adapting process parameters. The zinc can be collected and reused in the conceived process." The porous silicon layers show an encouraging battery performance, which is demonstrated by an initial charging capacity of more than 3,000 mAh/gSi and a comparably good cycle stability.

...

The scientists at the Fraunhofer FEP are now looking forward to collaborating with battery manufacturers to transfere the results into high-performance products. They are open to cooperation.

Her er et eksempel på en realistisk batteriteknologi basert på Si-nanowires kombinert med grafikk i anoder. Presentasjonen har fokus på EV og noe om batteriproduksjon og -teknologi. EV-nasjonen Norge er beæret med en slide - hurra! Gjemt inni linken til presentasjonen fra mai, ligger noen tall som kan gi en pekepinn på hva OneD Materials' teknologi kan innebære når den blir skalert opp (foreløpig til 100 tonn/år).

Prisen på silan er stipulert til kun 10 $/kg, så betingelsen må være en etablering nær produsent. Det er ikke sjans at REC Silicon leverer volum til denne prisen i konteinere, så da må de eventuelt samlokaliseres.... !

-Er det fra s 22 ?

Korrekt, R!

Side 22 er den mest interessant utregningsmessig hva gjelder denne anodeteknologien, men jeg synes at side 36 også er oppløftende.

For en batteriproduksjon som ligger inne i kapasiteten som kommer inntil 2029, ville det altså har krevet silan tilsvarende 1000 % av dagens "markedssilan" dersom denne anodeteknologien ville ha blitt brukt uforandret for alle batteriene.

Amastan Technologies invests in battery product development

US-based Amastan Technologies has increased its investment in the development of materials for battery products, on the basis of strong performance of prototype materials and cells. These investments are across areas including personnel, testing and characterisation labs, dry room and facilities. The company will be exhibiting at Battery Show in Novi, MI.

"Universal electrification and its impact on the battery market growth not only represents a significant opportunity for Amastan but is one where we can have a profound impact on changing the way that materials are made today," said Aaron Bent CEO of Amastan Technologies. "Our UniMelt manufacturing process allows us to produce any chemistry without being held to the restrictive rules of co-precipitation. Based on some exciting results in NMC, solid-state and silicon anode development, the company and investor group has decided to take a larger position in the battery market."

These investments follow last year's announcement of a US$1 million grant from the US Department of Energy aimed at reducing the cost of manufacturing of EV batteries. The accelerated development has enabled Amastan to establish new development and commercialisation plans with several incumbent commercial players in North America, Europe and Asia.

Richard Holman, VP of Amastan's Battery Business, said: " Our UniMelt manufacturing process collapses production times from days to 2 seconds and significantly reduces cost by 50-70%. We are already seeing close to matching best-in-class capacity of NMC materials. This combined with our advantages in production time and costs underscores the power that comes from decoupling chemistry from co-precipitation."

Greit alt dette,men hvor er den konkrete linken til REC? Jeg ser ikke at dette påvirker driften til REC direkte. Indirekte så vil høyere etterspørsel gi bedre pris,men det kan ta lang tid før det slår inn i regnskapet....

Godt spørsmål, Milkshake. Torvald har hatt i følge han selv et tyvetalls beilere på besøk, da for å se på mulig samarbeide om batteri leveranser. Meg og markedet bekjent er så langt dette en missing link? Elkem leverer som kjent over en lav sko til batterier. Så hva de roter med der borte er ikke helt lett og bli klok på.
Kanskje noen i Halleluja klubben kan oppklare saken?
Jeg tenker det er en grunn til at aksjen handles under 5'ern (50👂før omvendt splitt)

Jeg har bare opprettet en tråd hvor man får oversikten over batteriutviklingen. Fordi batterier vil kunne bli RECs neste store pengebinge. Om det blir det, vet vi jo ikke. Men veldig greit å følge med, spesielt på de batteriteknologiene som inkluderer silisiumanoder. Som vi vet ofte baserer seg på silangass. Men også konkurrerende teknologier er greit å holde øye med, så vi får et bedre innblikk i hvor realistisk det er at nettopp silisiumanoder vinner frem.

Det var også snakk om interesse for nabotomta! Tessla var da nevnt. Det har liksom kokt bort i grøten....2020 skulle liksom bli REC sitt år. Vi får se!!

Legger ved en link til en beskrivende artikkel med fokus på anodeteknologi. Kanskje litt for mye fokus på det teknologiske, men ikke alle alternativer ofres like mye oppmerksomhet. Tror det er tilfeldig. Mange patenter og mye fokus på IP rettigheter. Potensialet er stort. Merker meg utsagnet:

"The anode is worth 10–15% of the total cost of a lithium-ion battery, according to Chloe Holzinger, an energy storage analyst with Lux Research. The global anode material market could be worth $10 billion by 2025, she says."

Og dette er bare starten!

Som artikkelen beskriver, er det mange alternativer. Men det er spennende å følge med på når og hvem en stor batteriprodusent velger som samarbeidpartner eventuelt. Dette kan jo og få følger for avsetningen til REC Silicons produkter.
