Sila's Battery Breakthrough Is A Big Deal For Mercedes-Benz!

Published 2022-05-19
Earlier this week, battery startup Sila (in collaboration with Mercedes-Benz) announced it would be working with Mercedes-Benz to supply it with Sila's Silicon Anode technology for the battery pack in the upcoming Mercedes-Benz EQG SUV.

Here's why it's a big news.

    If all the battery breakthroughs I have heard about, turned out to be true, then EV cars would travel 10000 miles on one charge.
  • @johnmarriott9151
    Thanks so much for your hard work! Well wishes to your wife! I’m so glad to see more companies building battery’s in the US. I wonder where they’ll source their other materials though.
  • I thought the big problem with high silicon was the size change with SOC. let’s hope they have solved that one.
  • Maybe I missed it, but how many charge cycles is this good for? It seems longevity is the main problem with high Si Anodes. Maybe G Wagon owners don't care as they primarily lease?
  • @truhartwood3170
    I'm sure we'll see some leapfrogging in the battery tech coming out of existing and also startup companies. That's why I'm not investing in battery companies. The leader today, or the most promising looking startup today, could be blown away by some new chemistry coming out of the tenth largest battery company, or a totally new startup. It must be stressful building a production line when you know that before you're finished there will be a better battery developed.
  • @alancapes5644
    Interesting, thank you, but skepticism is required. The most important tech is the one that can scale to large volumes at lower costs. Also no mention about density by weight, charging rate and longevity/ cycles, if they aren't talking about those things I have to wonder why.
  • @nadieselgirl
    Getting closer and closer to the vehicle with the energy density I hope for!
  • @shanefiddle
    Great to see mainstream automakers FINALLY making serious electric vehicles! Thanks for the update on the latest, great video as always. That was a nice metaphor of the train for your non-technical audience.
  • @javonfair
    Sila is planning on opening a plant for anode materials in my hometown. Super excited! I'd love to go back and work there if I got the chance!
  • @judebrown4103
    Loved the tube train analogy... really helped my non-numerical brain to understand. Exciting times, thanks for another great report Nikki🌈👍
  • @arpinchock
    Any news of this tech works on lithium iron phosphate batteries as well?
    Most electric conversions I know of use these instead lithium ion because of thermal runaway problems etc…
  • @longrove5710
    Thanks for the update on this technology. Sorry if I missed it but was there any estimates on density per kg at the pack level?
  • @swanvictor887
    thanks for the video, fascinating stuff. One little 'Irk' I would like to mention (not really important but has some social significance). I noted the new factory in Washington State, subsidised for $100M, and I noted it seemed to be a greenfield site...this 'Irks' me somewhat. In the UK, we have many, many, many towns and cities with huge areas of dereliction and decay (Swindon, anyone...remember...where Honda used to work?) and I would bet my pension that in the USA, there are similar situations...erm...Detroit, Pittsburgh, parts of California...?
    Don't you find it...what's the word....counter-intuitive (?) that we dig up a greenfield site while we have acres of cities, rotting?
  • @benholroyd5221
    Is it a good thing that car companies are investing directly in battery tech? In the short term yes it bring much needed investment and pushes technology along but in the long term every car company has different battery tech so you could end up where various advantages are spread around, if you want long range you have to buy an X, if you want fast charging you have to buy Y . It doesn't seem very good for competition if such a fundamental part of the product is proprietary.

    I suppose licensing is a thing but it seems analogous to one company having control over the petrol engine, one over diesel, one over lpg etc
  • @1RikAtiC1
    The car of Lightyear is presented tomorrow, if we build all cars like that , we would need way smaller batteries and 80% less charching stations. ( Aptera & Sono Sion are great in that way to )
  • of course it is expensive, but it is a option to electrify old ICE cars with these high energy density batteries to get an amount of range in the car that is a bit more satisfying.
    it is difficult to get all the batteries in an ICE car where you have such a cluttered space and also limitations in maximum weight.
    i am always happy to hear battery news. half of them gives us a realistic view to the progress that is happening now and in the future. that is very satisfying.
  • @mrfester
    I still would like to know why modern electric vehicles 2022 still have a 12 volt battery. Can't they dedicate a single cell pack for those functions or something.
  • @kensmith5694
    By time the car is in production, it is likely that the lithium-sulfur batteries will be on the market. Lithium-sulfur is about 3 times as energy dense. Someone found a way to prevent the dendrite problem by capturing the sulfur in carbon nonotubes. When that technology gets on the market, ICE cars will completely be toast. An electric car will have more range than an ICE one.
