1. We have 2 bonus videos with ~40 minutes of extra content this time:
   1. Breaking down fast charging tech: https://nebula.app/videos/techaltar-how-fast-charging-took-over
   2. Interview with Counterpoint Research: https://nebula.app/videos/techaltar-interview-with-peter-richardson-counterpoint-research

   Hope you enjoy it, and if you don't have Nebula yet, the best way to get it is through our bundle with CuriosityStream here: https://curiositystream.com/techaltar

2. Slava Russia!!!!

3. Capitalism Ruined new research.

4. It's a shame so many companies are touting e-vehicles as "the solution" to the climate crisis. Walkable cities that are not dependent on cars, fossil fuel or electric alike, are a much greater solution but no automobile manufacturer will admit that, obviously.

5. We have about 15 years left with petro cars. People are delusional if they think we are going to be buying/selling/using cars the same way today and 15-20 years from now. There will come a reckoning. Electric cars are not the solution and will die out 100x faster than the petrol car.

6. I want fusion cells batteries

7. Why not just insure humane mining conditions on the list of the companies and consumers using the mines outputs? It's not an immutable given that the system as it is has to remain so

8. As I see it these faster batteries are a useless upgrade.
   I mean sure the phone can charge faster but you can still use a phone while it's charging.

   The only case really fast charges could even be argued for is if you need the phone operational 24/7 for work or something.

   By work I am speaking about jobs that may result in someone's death or injury.
   Like for example construction worker's or people who work with electrical equipment.

   I mean aren't batteries more than fast enough as is?
   Why must they be made faster ?
   This is coming from someone who has a phone that charges fully in 45 minutes.
   To me this shit is overkill for no apparent reason.
   Who need's a phone that can charge fully in 8 minutes?
   Is the leap in faster batteries justified really?
   Or is it just a useless upgrade that is irrelevant for the most part?

   I see people with an 8 minute max charge phone that they brag about.
   I am thinking to myself "like so
   what "?
   "The phone can charge really quick be deal".

9. Hopefully solid state batteries and Galium Nitride becomes the norm.

10. Batteries suck

11. Could we please start referring to battery capacity in mWh instead of mAh please?

12. Watching this on my 15,000 Mah battery phone

13. I missed the days phone battery was swappable, or at least being easily replaced

14. How about graphene

15. umm wasn't anode the positive side and cathod the negative side

16. With a lot of things in this world we have to work with the best options available. So comparing to an hypothetical ideal world is nice for visions, but you can't get around the state of the science.
    This problem is a lot older than phones as even electric cars existed earlier, but electric battery storage (with high energy densities) simply seems to be a hard thing to do.
    You gotta squeeze them electrons real tight😂

17. Hey, the videos are great but there are pretty audible white noises that come with the voice. I'm writing it because don't know if you are aware of it.

18. Solution: we go back to landlines and pay phones. Only a handful of people need a battery operated super computer in their pocket and it's not us.

19. so little kids are holding up the whole of the worlds cobalt production with their little fingers… got it

20. Evolution is certainly helpful but, for long term viability, we need a revolutionary solution. Smartphone performance, for example, is already seriously hindered by this antiquated tech. At this point, processing power can only really be increased if we start plugging our devices into wall sockets again.

21. You sound like Adam Something

22. Perhaps the most significant problem is that batteries actually degrade, which means that their capacity slowly becomes smaller and smaller. Which means after a certain amount time you will need to replace it.

23. Capacity or charging time is one thing, but how about longevity ?
    Given how precious and rare the raw materials are, batteries should last at least 15 years of use to begin with, and more idealy 30 years should be aimed at.
    Of course that means that eventually, shape and sizes should be more standardized so the batteries can be used in multiple devices.

24. Good video with awful lot of ads.

25. 3 out of my 4 Gopro batteries have swollen, very expensive and poorly made

26. Americans criticising China everytime they can………. Its not really the cobalt but actual jealousy

27. I am reminded of SUPEERVOOC Oppo charging and deciding if I should buy one for my smartphone and tablet. Theyre not Oppo devices but it if maximizes charging speeds and efficiency for mobile tech, sure I will buy.

    I'm not surprised Li-ion batteries have remained somewhat the same in terms of making them last a week or two on one charge but these new initiatives to make alternatives to legacy materials is a start to go on a. global shift from Li-ion. I was hoping to have seen Hydrogen battery technology in the video but it seems too early or unsuitable for adoption. I know it's used primarily with prototype racing cars and thought improvements were made to be feasible in a near future for consumer-tech.

28. Please research your videos better. Not all lithium batteries uses a lot of cobalt. Russian nickel is not the right quality for batteries. Different cobalt battery chemistries uses way less cobalt than others.

29. 10:12 you mean wh/kg

30. I had an early smartphone. HTC 6700. That thing lasted 2 days with a 1350 mah battery

31. i believe the future will involve a processor that will not need raw electrical power to operate.
    then the need for stronger battery's will be obsolete

32. I wonder the collective environmental impact if consumer electronics turned to focus on efficiency. e.g. the difference in power draw when Apple switched from Intel (x86) to ASi (ARM) on Macs. I know battery isn’t an issue on a iMac, however, having significantly less power draw across thousands and thousands of appliances and devices in homes add up. Improved efficiency in TVs, fridges, ovens, toasters, microwaves etc.

33. Sounds like "peak consumption" has arrived. EV's certainly aren't going to save us or "the Happy Motoring" age…🤔

34. keep being you tech Altar, i was unsubscribe from you but i back here rn

35. It’s been 3 years and my phone’s battery barely lasts 1-2 hours

36. Great video 👍🏼❤️

37. Cobalt isn't mined using slave labor. taking away cobalt production is literally taking away jobs from the most vulnerable people. Do you hate the global poor?
