    Took me a while to understand anode and cathode definition and there is a lot of confusion out there due to different applications, but just remember: Anode= electrons leaving (i.e conventional current enter) ( on the external circuit) Cathode= electrons enter (i.e conventinal current leaving) ( on the external circuit) this means in a rechargable battery the anode and cathode change place under load and charging. In electronics you have diodes with fixed anode and cathode and the definition of anode and cathode are true in the forward biased direction. Thanks for the video, great work!

    I disagree with regard to the visualisations of things. I'm not talking about quality of animation, but about what's shown, while the script is read. In this video: pretty footage of cars, while he talked about things happening on the molecular level. What? I've hoped that both Real Engineering and Wendover Productions would get better at this since pretty much the beginning of their channels, but haven't found it to be the case. Comparison of amounts for example, would massively benefit from improvement. "Mice weigh this much, and cows weigh X times more!" - Show. Don't tell. Show 2 boxes, where one is X times as large as the other.

Thinking about how you use/charge those batteries in your daily life can make their lifes longer, e.g. letting you use your laptop/smartphone longer with a healthy batterie. The Tesla does this by itself, but your phone only does it limited.

    Capacitors could be great for drag racing. You're only going a quarter mile, so energy density isn't important. If you actually want to drive your vehicle anywhere, they won't store anywhere near enough energy for their size and weight. That's why Tesla (and others) use lithium ion batteries exclusively. I shouldn't have to say this, but the people doing this are not stupid.

    @MaciekBroken If you want to be entirely correct the negative electrode is the anode when discharging since a oxidation takes place there (Li->Li+ + e-). When charging the negative electrode is the cathode since a reduction takes place there (Li+ + e- -> Li). For the pos. electrode it's the other way around. But usually the neg. electrode (graphite) is referred as the anode and pos. as cathode (metal oxide) since it's in discharging direction.

    Then also I like the dive into the engineering side of things. I can only speculate at Nissan's engineering development and testing program, but the fact they did not test over a range of temperatures is a fairly understandable mistake that seems incredibly obvious in hindsight. Its even possible individuals in the organization suspected temperature might have some impact, but the organization as a whole was not capable of foreseeing this or committing the necessary resources. Try setting up a test lab, then have some one tell you need to move all the equipment into a climate controlled chamber (which may or may not exist or be available to the group), while working under your typical deadlines and resource constraints. Something tells me the EV group would not have top priority at company primarily dedicated to ICE vehicles, unlike Tesla, whose entire product line is EV. However like I said, this is speculation at most, who knows what how the actual story went..

    For anyone interested in the Mergers & Acquisition process, the Board of company A decides its in their company's best interests to merge with or acquire company B. They do their due diligence, scouring publicly available information about the other company and crunching numbers to see if their hunch holds up. If it does and its not a hostile take-over they send their offer to the Board of company B. They are duty-bound to study it. Why? Because they are legally bound to act in the best interests of their company's stakeholders and especially their shareholders. So the company could be doing great, just like you could be really happy with your house, but if someone offers you 10X its market price you have to consider it, talk to your partner, think about your kids. Company B's Board has to study the offer and then tell its shareholders about it along with their recommendation to accept or decline. Let's say the shareholders accept, both boards still have a little more work to do. Now they agree to share more data with each other, things that may not have been in the public domain and they confirm the deal is still good and there are no nasty surprises. When everyone is on board, this is when it goes to regulators who's job it is to consider the public interest. Either they give their blessings, suggest amendments or deny permission.

    Great video but you merged some of the cell ageing mechanisms. You covered the growth of the SEI pretty well, but you didn't cover the issue of the electrolyte digesting itself with side reactions, which is worst at high temperatures and/or high voltages. This, if i recall, is what killed the Leaf. Basically SEI issues increase with the number, depth and rate of cycles (high and low temperatures also play a part). By contrast, parasitic reactions within the electrolyte and between the electrolyte and other components don't need ANY cycles. Just hold a lithium battery at the top of its charge curve and keep it warm and it will electrochemically destroy itself even without you cycling it. Again, this is where they went wrong in testing the first Leaf batteries. They thought cycle number was the main aging factor when it was actually just cumulative time spent above half charge that was really killing their batteries. If you test cycle a battery 500 times in a month it spends only 2 weeks above half charge and the test results look splendid. (I refer to half charge for simplicity's sake, but the capacity loss/voltage/temperature curves are obviously on some kind of exponential function that gets way worse at the extreme. You would expect electrochemical engineers to know about this from first principles but somehow it must be less predictable than one would think). You emphasise the clogging of the SEI, to which both of the above contribute. It is true that car batteries are usually retired because internal resistance prevents the car delivering power fast enough, and the main effect of a clogged SEI is increased internal resistance leading to reduced power density. However, I believe total capacity decrease is also a big factor in the decision to retire a car battery. Capacity decreases because lithium gets irreversibly tied up in side reactions, as well as in the reactions that build up the SEI.

    This will greatly help solar power technology, I think the biggest cost with solar power involves battery expenses. Every time I plan a new solar system for my house the biggest cost is always the batteries.

    Do a search for diy powerwall on youtube. Seen people build for as little as 300 usd per kw/h with new but surplus cells. There are companies that only deal in surplus new cells and fully tested used cells and sell for a fraction of new ones.

    @@zereimu yeah, that 300 per kw/h was an extreme example done by very dedicated and creative people though. I do not want you to get to excited and be disapointed :). But it can still be done a lot cheaper then the commercial solutions out there currently without to much hassle and with of the shelf parts. Even at 500 or 600 dollar per kw/h it is still a lot cheaper then commercial solutions and that is certainly doable if you shop around. Ahh well, maybe you are just as dedicated and creative and you are able to beat those guys. It is kinda a competition going on to be the one who finds the cheapest solution. If you enjoy that stuff as well and have the time i am sure you can do it even cheaper! Prices are constantly coming down on all this stuff.

    Actually, looking at the underlying technology, Ram is pretty much just a grid of capacitors, where nand flash is a chemical reaction very similar to a battery, this comparison makes much more sense. SSD = chemical batteries RAM = capacitors

    I loved the "corporate owned tech channels" and immediately highlighted Seeker bit. That is quite a move there. Mixing the steady flow of Tesla batteries and the surgees to be handled by the Maxwell ultracapacitors. Very good.
