   I am old enough to remember youtube before monetization, like, comment, and subscribe. It was great. Better than it is now. If others remember the dawn of the Internet, it was a similar feel. People definitely did and still do make videos f

   Asking for a friend... In all seriousness, I was alluding to the likely way that people get on these lists. Success doesn't necessarily mean being a great technical person, it means knowing exactly where, when and how to grease the whe

   How would one try to make it on one of these lists? No one said these people aren't smart or likely to succeed.

   For me, this signals CATL is either actually on the verge of a breakthrough, or desperate and in big trouble. If the technology is brand new, how can it have been thoroughly life and cycle tested already? I will believe the batteries are tr

   You're right, and it's not just a minor pet peeve. It's a major error that recurs throughout the article and it destroys the credibility of the website and reporter. They even refer to "energy intensity", which as f

   Yes, there are tradeoffs with all of these. We can easily get one or some good looking stats, but to get good results with all of these parameters is the real challenge. The claims about new battery chemistry are rarely farfetched or inaccu

   We are indeed happily discussing how to assign each human a unique serial number, without too much discussion of why or if it should be done.

   Nowhere in the article does he say the industry is ripe for disruption. Can we please change the title to something more accurate, such as "Lithium ion technology is not going to be disrupted in at least the next 5-10 years, inventor s

    Lithium is great, the low atomic mass of 4 is close to as good as you can get. They haven't invested trillions, the lithium ion technology is in a relatively young and poorly optimized state and is similar to the state of the art 40 ye

    That's correct about the specific energy, it's partly related to sodium's atomic mass of 23, vs lithium's atomic mass of 7.

    Alternate theory: open source is destroying the future. In fact, significant progress is occurring from concentrated capital investments made by public entities or corporations, and development slows down or regresses once open source alter

    You are right, it's not something that needs to be enforced or demanded on a personal hobby project. You can write documentation and software for yourself, and share it for no particular reason, or write documentation/software for

    We may or may not develop processes to efficiently recycle the "black mass". For now, these processes do not exist. Battery recycling may go in a different direction than it's currently heading. We may decide to focus on sepa

    For each element, I believe there is a combination of electrolysis, electrowinning, leaching and other hydrometallurgical and refining processes that is used to refine from ore into a pure state. In the article, lithium is extracted from th

    Yes, I think you're right that this is the state of the art at scale. I wish the article went into a little more detail on the extent of technical achievement that was reached in commissioning this facility. Never mind the core process

    I do have a little familiarity with lithium-ion technologies, but no direct insight into battery recycling. Please correct me if I'm mistaken. I absolutely do think that "recycled" battery materials are being stored as combin

    This is the correct way of thinking, and is widely applicable to many commonly recycled materials. Wood, aluminum, steel, and some plastics can be efficiently processed in this way. Battery materials and applications are different. They can

    Yes, vehicle batteries and stationary storage are used in much more "forgiving" environments than laptops and power tools, when it comes to cell life. Lower power draw, better battery management systems, less temperature fluctuati

    Chromium, manganese, iron, cobalt, nickel, copper and zinc are elements # 24, 25, 26, 27, 28, 29, 30. The processes to separate them are currently resource-intensive and expensive. They need to be separated by conventional smelting and ref

    I think the "Motivation" section is the most important section of documentation. Why is this great and why should we keep reading?

    Pretty pathetic "recycling": 1. 80-90% of input is not even batteries, it's scrap from woefully inefficient and low yield battery cell manufacturing 2. "Recycling" consists of mechanical shredding to combine all of

    I think FreeCAD or equivalent is the best place to start. See if you can find some sketching and parametric modeling tutorials in FreeCAD and follow them, then design your part. FreeCAD because it's free, open source basis and parametr
