Sila claimt "betere Li-ions" in productie te krijgen tegen 2024
Per kWh lichter, kleiner, en sneller laden, tot 20% meer rijbereik enz...
De Mercedes EQG, of de nieuwe electrische terreinwagen van Mercedes zou ze krijgen. Die heeft ze zeker nodig...

Innovatie / Elektrische Mercedes EQG krijgt slimme Sila-batterij
GESCHREVEN DOOR FRÉDÉRIC KEVERS OP 17-05-2022
De Mercedes EQG, de elektrische G-Klasse die in de loop van 2025 verwacht wordt, krijgt een door Sila ontwikkelde batterij met extreem hoge energiedichtheid. Dat zou de massa van de elektrische terreinwagen binnen de perken moeten houden.
Door hun robuuste bouw kampen terreinwagens sowieso met overgewicht, voeg daar een enorm batterijpakket aan toe en je krijgt tanks. Met de nodige negatieve gevolgen voor het rijgedrag, de veiligheid en het verbruik. De zoektocht naar een gepast dieet voor de Mercedes EQG, deed de Duitse constructeur uitkomen bij Sila Nanotechnologies. Dat is een start-up van voormalig Tesla-ingenieur Gene Berdichevsky, die bezig is met de ontwikkeling van silicumbatterijen met een extreem hoge energiedensiteit - van 20 tot zelfs 40% hoger dan bij een conventionele lithium-ioncel met grafietanode.
LEES OOK EQG Concept gaat elektrische Mercedes G-Klasse vooraf
Bekijk je de batterijen die Mercedes momenteel gebruikt voor de elektrische EQS, die een massa-capaciteitsverhouding van ongeveer 6,5 kg/kWh heeft, dan bedraagt de gewichtsbesparing voor een accu van 100 kWH ongeveer 130 kilogram. Met de Mercedes EQXX experimenteerde Stuttgart reeds met compactere en lichtere batterijen, wat resulteerde in een run van meer dan 1.000 kilometer op een lading. Nu goed, intussen is Tesla aan het testen met de Gemini-accumodule die een rijbereik van 1.400 kilometer belooft.
LEES OOK Mercedes Vision EQXX haalt meer dan 1.000 kilometer
Dit nieuwe batterijtype wordt ook gebouwd door Sila Nanotechnologies, in een fabriek in het Amerikaanse Washington die pas in 2024 operationeel zou zijn.

Recenter nieuws, ook van Sila zelf:

Door simpelweg over te stappen van traditionele grafietanodes naar Sila's Titan Silicon, belooft de Amerikaanse materiaalleverancier enorme upgrades, waaronder een toename van 20% in bereik, een afname van 60% in oplaadtijd; tot slechts 10 minuten, een vermindering van 20% in benodigde ruimte, en als klap op de vuurpijl een vermindering van 50-75% in koolstofemissies dankzij het fabricageproces van silicium.
Maar misschien wel het belangrijkste voor een koper als Mercedes, is dat Titan Silicon wordt geproduceerd in de Verenigde Staten, waardoor de Duitse autofabrikant in aanmerking komt voor belastingvoordelen van de IRA.

Mercedes takes out all the stops with new EQG battery material
Posted on April 4, 2023
Sila, a battery materials company, has released the specifications for their newest battery anode, which will be used in the upcoming Mercedes EQG.
As automakers have continued to refine their development of electric vehicles, the quality of the materials they use, particularly within the vehicle’s battery, has increasingly grown in importance. Now, Sila, a battery materials supplier, has outlined the numerous benefits of its new “Titan Silicon” battery anodes, which will debut on the upcoming Mercedes EQG by the middle of the decade.
Mercedes is expected to roll out numerous massive platform upgrades alongside the EQG, which will be the company’s first all-electric variant of the fabled G-Class. And while using Sila’s Titan Silicon battery anodes may sound insignificant, new data from Sila proves otherwise.
Simply by swapping from traditional graphite anodes to Sila’s Titan Silicon, the American materials supplier promises massive upgrades, including a 20% increase in range, a 60% decrease in charging time; down to as little as 10 minutes, a 20% decrease in required space, and to top it off, a 50-75% decrease in carbon emissions thanks to the silicon manufacturing process. But perhaps most important to a buyer like Mercedes, Titan Silicon is produced in the United States, helping the German automaker qualify for IRA tax incentives.

Sila Introduces Titan Silicon, Nano-Composite Silicon Engineered for Mass Scale to Power a 20% Increase in Vehicle Range and Dramatically Reduce Charge Time
04 Apr 2023
Sila, a next-generation battery materials company, announced the availability of its high-performance nano-composite silicon (NCS) anode, Titan Silicon. Titan Silicon is the first market-proven, safe, and clean full graphite anode replacement engineered for mass scale to dramatically boost EV performance and address key consumer pain points. According to a consumer survey recently commissioned by Sila, nearly 90% of respondents who own or intend to purchase an EV view high-performance battery technology as more valuable than other tech enhancements or luxury features, including autonomous driving capabilities.

Graphite anodes and simple silicon compounds (Si, SiO, SiO2 ) for lithium-ion batteries have reached their energy limit, which stifles EV performance. In contrast, Sila solutions deliver the EV experience drivers want to reduce anxieties around range and charge time. For automakers who want longer range, Titan Silicon can deliver a 20% increase in range today, which could be up to 100 extra miles for some EVs, with a development runway to double those gains in future releases. Titan Silicon can also dramatically improve battery charging time, charging a battery from 10% to 80% in just 20 minutes – even if your charge time is currently as long as 60 minutes. Future releases will reduce that time to approximately 10 minutes, a standard similar to refilling a gas tank. Notably, Titan Silicon achieves these gains without sacrificing cycle life or safety while maintaining low swell, comparable to graphite anodes. And with Titan Silicon, automakers can benefit from up to a 15% reduction in battery weight and 20% increase in space, enabling higher vehicle efficiency and the addition of innovative designs and features.
“Titan Silicon is the highest performing nano-composite silicon in the market today. Our battery and materials teams are constantly iterating and improving upon our chemistry to deliver the best, and most cost-efficient results possible,” said Gene Berdichevsky, co-founder and CEO of Sila. “With the wide adoption of EVs, consumers are looking for best-in-class solutions that deliver best-in-class performance, and our solutions provide just that: longer range and faster charge.”
The formula used to engineer Titan Silicon powers products in-market today – in the WHOOP 4.0 fitness tracker. Since then, Sila has optimized its high-performance nano-composite silicon for mass production, which is scheduled to come online in the second half of 2024 in Sila’s facility in Moses Lake, Washington. The company also hit a major scaling milestone, completing the development of new equipment for its Moses Lake facility, making the timing right to announce worldwide availability of its NCS solutions under the Titan Silicon brand. Sila plans to manufacture enough material to power one million EVs in the next five years. Last Spring, Mercedes-Benz, the company’s first automotive customer, announced that it had selected Sila’s NCS for its luxury electric fleet, starting with the Mercedes-Benz G-Class, due out by mid-decade.
Key features and benefits that differentiate Titan Silicon solutions from others include:
• Drop-in solution: Titan Silicon anode is 100% compatible with any cell form factor (e.g., cylindrical, pouch, and prismatic) and any gigafactory.
• Full or partial replacement: Only Sila offers the choice of full or partial graphite replacement based on an automaker’s or cell manufacturer’s performance goals and product roadmaps.
• Mass produced at the highest quality: Titan Silicon solutions are manufactured in the U.S. to automotive quality standards to ensure safety and reliability at the scale needed to meet volume demands. Sila is also ISO 9001:2015 certified.
• Syncs with existing supply chain: Titan Silicon can work with any co-product, which eliminates the need to change partners or operations.
• Lower CO2 footprint vs. graphite: Titan Silicon generates 50-75% less CO2 per kWh than graphite during production.
• US made: Today over 90% of graphite is mined and/or processed in China. Sila offers an alternative anode material source for automakers that want to meet requirements for Inflation Reduction Act tax credits.
