Added 2025-08-05 12:53:41 +0000 UTCWe’d love to hear your feedback and suggestions as we wrap up work on our next video. Please let us know your thoughts!
Thank you so much for your time and help.

Sounds so good and interesting but it begs for the animation for me to sink in. Thx? Good so far!

2025-08-06 20:56:59 +0000 UTCBut I should keep asking, where are we in the path of finding better batteries? If any info or knowledge can be extracted from companies and teams working on new technologies, there can be a video with huge audience!

2025-08-06 09:27:15 +0000 UTCTo express how much we really needed to have this video, I should say there was no single week in the last ten years of my life I haven't asked myself: "why batteries don't have more capacity and why I have to charge my laptop every few hours? Why don't we have infinite energy?". This topic has the capability of turning into many great videos. I see many placeholders which is only a good thing because it means animations team is going to do lots of great work, because they always do a great job! I'm impatiently waiting for the final results.

2025-08-06 09:14:53 +0000 UTCGreat insightful and educational video (as always). Love your content. Couple of pointers: 1) for the battery ion animation - use a bit more vibrant colour palette if possible. 2) could make it into a series - by exploring other related battery tech - and you could include a hint to that in this video. Like blade batteries in BYD cars and how they resist fires even when punctured. Your audience won’t mind a few extra minutes - they would rather cherish it.

2025-08-06 04:08:42 +0000 UTCGreat video, lots of info dealt with. I like this and want more of it. @14:30 "we made a special cell where you can actually see the dendrites forming" - Shakey footage difficult to follow, and we don't see the speaker until after this footage. The stable footage of the transparent battery looks great though @15:13 "...if we go too fast" - What did he do to go from "ideal reaction" to "too fast"? @15:15 dendrite footage - Is the dendrite formation real-time? - Are those dendrites forming fractals? It looks cool @17:24 "...this compound already had lithium in it" - Does it come out of the ground that way? The phrase "already had" suggests that no action was necessary to make it that way. @24:08 newspaper - Thanks for the scan. Paused and read; that garage was doing a lot. @25:11 "...competing companies..." - How did the competitors get their hands on the same battery tech? Wasn't it being kept secret? @26:58 "...the price of lithium batteries..." - Can you color-code the two Y axes to correspond to the two line colors? @35:50 "...it depends on how well we can hold on to it." - Good message to end on. Could this a message to start with? The video is a history of batteries, but doesn't ask "why store electricity in the 1800s". If you do another battery video: - _Fully_ solid state always seem to be just on the verge of exiting the lab - Why are most batteries round instead of square? - "Tabless" batteries with the same chemistry have much higher charge and discharge rates (Note the abstract from Goodenough's paper @17:19, where "current densities up to 4 mA cm^-02" indicates dependency on surface area somehow) - Different chemistries open up if you don't need high energy density and it's just going to sit on a slab of concrete for 20 years (ex: liquid metal) Looking forward to whatever you put out.

2025-08-06 02:56:07 +0000 UTCI liked the video and the historical deep dive. As mentioned by someone else, I felt the animations with the lemon confused me a bit, perhaps due to the deep zoom, keeping me from seeing the big picture (are the particles moving through the lemon or through the wire right now? ) I couldn't find any factual problems, but many graphics are still missing. I am not qualified to judge the reaction formulas. I did spot a typo ("degrated") at 29:51.

2025-08-05 23:09:12 +0000 UTCI was there when we tried to introduce lithium ion batteries into portable computers at Apple, we didn't succeed initially for a number of reasons the biggest one being some of the prototypes caught fire. There is a reason they no longer make lithium ion D cells, Sony could probably talk at length about it. You didn't spend much time on the safety mechanisms that are in these cells or the requirement to balance the cells when used in series. Having said that the video would probably get too long if you covered all the problems and requirements to use lithium ion batteries.

2025-08-05 21:29:48 +0000 UTCAlso, since you’re doing the history of batteries, and including risk as a central theme, perhaps you could mention the risks of lead-acid batteries.

2025-08-05 21:16:22 +0000 UTCExcellent! I watched every minute. I haven’t found any errors. My only suggestion is that you might want to open with a short but catchy scene of a battery explosion or something similarly dramatic, then close at the very end with that opening scene repeated — but with a few moments added as a resolution to the original opening scene.

2025-08-05 21:10:03 +0000 UTCThat was (or, will be) one of THE best Veritasium videos ever. (Maybe second only to the one that said 99 was the least commonly chosen random number between 1 and 100.) I didn't mind the placeholders, because the voice over essentially described what would be there...
Kate Proctor
2025-08-05 21:00:57 +0000 UTCReturn them to the stores that sold them (or sel similar items).

2025-08-05 19:50:09 +0000 UTCToo many placeholders

2025-08-05 17:27:50 +0000 UTCOne thing that might be valuable is to add a segment on how and when to dispose of Li batteries. I have numerous battery packs, a few of which seem to have "swollen" a little. I certainly don't want to toss them in the landfill but I don't want to keep them around the house, either. What to do ... what to do ...

2025-08-05 15:38:33 +0000 UTC5~9min I got lost here and had to re-watch because l didn't understand the fundamentals: why does Zinc want to get rid of an electron? Why doesn't it do that by itself? What makes it go into the lemon juice? I don't visually see the electron flow through the circuit, so instead of focusing on the electric flow, I was focused on Zinc flowing into the juice, almost as if the ions were going into the cooper. I think this explaination could be represented better visually. Derek's explanations are usually really down to earth but between 8:22 ~ 9:12 it sounds like techno babble because I didn't understand many of the definitions.

2025-08-05 15:20:01 +0000 UTCThis video is Great! Poorly managed batteries sound to me like the biggest danger/issue that we have. We need to know and practice the best methods of recharging to ensure we get the most use out of our devices and that we do so without creating a dangerous situation by charging too quickly. I would recommend that some best practices of charging Lithium Ion batteries would be a good addition or good next project.

2025-08-05 15:16:14 +0000 UTC(Sorry, hit return before I was done) Just two comments: the line delivery at the very end led me to expect more, so the end of the video felt abrupt. I was also kind of hoping there would be a little more discussion about what to expect in the future from batteries.
John Murphy
2025-08-05 14:42:35 +0000 UTCThat was fascinating! All the twists and turns around bringing Lithum ion batteries to market were wild. And of course, the burning battery had me looking around my room at all the batteries in here… and there’s a lot…
John Murphy
2025-08-05 14:39:36 +0000 UTCThis was as usual a very instructive video. Also look forward to see the placeheld animations. ;-) I guess that talking about ongoing research with other techs or materials, such as solid electrolyte or calcium-based, will be for a future serie of videos...
Thierry Deval
2025-08-05 13:57:36 +0000 UTCI will be very interested in seeing once again the finished video with all the animation. You are such an absolute genius at producing complex ideas into relatively easy understandable explanations. Kudos
