                  Its actually the “went to church, talented white folk there”, posted by “fren”, somehow they learned random old dude was “88” which has no bearing on the story and isn’t usually something that comes up in short conversations, and the “I was like <common behavior from easily influenced person> before I did these things”

                  It gives recruitment/fishing vibes to me. If 100 people read it and 99 see ADHD and move on, but 1 person asks them how they could also feel good about themselves, boom, one more Nazi recruit. That’s how dog whistles work. You toss an innocuous thing like “88” in your story, it let’s those in the know that you’re part of the team and you’re on the job.

    I hope this article is well peer-reviewed. Otherwise this reads as if some LLM came up with the idea

    This title is pretty bad, the paper focus is in designing new battery technologies not magically restoring capacity on the batteries we have today.

    In the good ol’ days when I ran out of battery and every charger had a different stupid little connector, I often put my phone on the window still or heater to get a little bit of juice to do what I needed to do.

    I guess I am a scientist.

      Wow, this brought back memories of me rubbing my hands against my old Nokia battery in middle school to heat it up and get a couple extra %.

    Important note near the end of the article - they aren’t saying we should cook batteries really -

    “The team’s hypothesis is that the structural disorder developing inside LIBs may become a “tunable parameter” that, if tweaked using chargers at precise voltages to alter said battery composition, could be used to rejuvenate the batteries in our tech without fires.”

    This is a good old idea that goes back to the days of desulfating lead batteries with powerful shocks of high-amperage current. Might just need a special Healing Charger that applies the right voltage/current to dissolve the bad crystals in lithium-ion systems

      I remember recovering dead 18650 cells from laptop batteries and “restoring” them with a 12V modded PC PSU. Quite a few of them actually started working again and had some capacity for a few tens of additional cycles. Those cells were never left unattended in a charger and they were always only used in a device you could chuck in a moment’s notice.

      10/10 do not recommend.

        How did that process work? Did you just connect the +/- ends of the cell to the +/- 12v wires of the PSU and let it feed from the high-amp outputs? Imagine there’s plenty of amps on the GPU and CPU power wires

          Yup, just plugged it in there. The internal resistance of these cells was high enough that it limited the current somewhere between 3-8A. And this was done only briefly as these cells got quite…warm.

      With electric cars you might not even need a special charger so much as a special charging cycle. Its already the norm for cars to tell the charger what voltage and current they want, and its already the norm for cars to carefully control their battery’s temperature during charging.

      That’s not to say you’d necessarily be able to do this with just a software update, but its not too far off from the current paradigm.

        Yeah that’s a good point. Ours uses the same refrigerant system as the AC to cool the battery, and the actual “charger” for the battery is inside the car being controlled by its software etc. The cables that plug in on the outside are technically just power wires, with the charging brains inside the car. That would be amazing if they could update the software to rejuvenate the battery once a year or something.

          it would almost certainly need to be done at a fast charger, not at home unless it could do only a few cells at a time. Remember the golden rule: “Don’t set the house on fire by overloading the wiring”.

      Well, there is some data/rumours out there, stemming from a Dutch Tesla forum, that suggests that some fast charging might be beneficial for battery longevity. This seems to corroborate that. I can’t remember the case for always fast charging, though.

      Putting my LG G Flex which had a boot loop problem due to a soldering issue on the battery solved the problem temporarily!

      Edit: oh also that was the freezer

        I’ve known some old people to put their bootloops in the freezer because they think it won’t go stale as fast.

      In reality, this doesn’t affect the existing batteries we have, it’s just for future battery technology.
