                  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.

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

    Sounds like a horrible idea if not carefully controlled. Perhaps up to 80 degrees in an oil bath could redissolve some of the electrolytes. I guess it could work. Anything above 100 is asking for trouble.

    Warning: heating earbuds batteries to over 300F also causes fires

    Reading this tells me the author has absolutely 0 idea of how physics work and is nothing but a blogger of consumer grade equipment. People like that should refrain from trying to understand how science or scientists work.

    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.

    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.

      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.

    How does heat mitigate the dendrites? Also doesn’t extreme heat damage the batteries? They barely hold up under high temperatures as-is.

      I think it has to do with whether or not the battery has a current going through it while hot. I imagine heat probably makes the lithium more soluable in the electrolyte liquid, then the disolved material migrates with the current flow. Heating it without a current flow might allow it to redissolve and at least distribute it more evenly so it doesn’t make one long spike that shorts the battery.

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

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