Lipo battery gas contains flammable and poisonous chemicals - including Hydrogen fluoride. Swelling slightly in normal use and occasionally rupturing is safer

Lipo battery gas contains flammable and poisonous chemicals - including Hydrogen fluoride. Swelling slightly in normal use and occasionally rupturing is safer over-all than off gassing all the time. From wiki: > Hydrogen fluoride is an extremely dangerous gas, forming corrosive and penetrating hydrofluoric acid upon contact with moisture. The gas can also cause blindness by rapid destruction of the corneas. https://en.wikipedia.org/wiki/Hydrogen_fluoride https://en.wikipedia.org/wiki/Hydrogen_fluoride

Okay I’m really going to prioritize throwing away my old android devices now.

  Throwing away is a real hassle. You often buy a new phone because the old one is broken. So data is on there but you cant turn it on. Get a drill out? Not sure I want to breath in that dust.

    Microwave? Might be easier to avoid the fumes than the dust from drilling. Probably easier to drill outside and wear an N95 mask and goggles though.

    Just put a soldering iron over the epoxy on the ssd chips, get it really hot to ensure the sillicon gets heated to at least 100C and your data will be gone forever in a completely non-functional chip.

    Buy an iPhone and don’t worry about recycling it because storage encryption means it doesn’t matter. You can never plan for when you might lose a device.

  No! Take those devices to electronics recycling. They DO NOT go into your municipal trash. Lithium-ion batteries can start fires inside your garbage truck, forcing the truck to dump its flaming contents onto the street. Electronics contain hazardous materials. And electronics contain valuable materials worth recycling. Where I live, it is illegal to put electronics in your municipal trash.

Most laptops use cylindrical cells for their battery pack, each one with a valve. I really doubt this is any kind of actual problem, more like an excuse given to reduce costs at the expense of the consumer. Standard lead acid batteries in every car and UPS also release H2S in vast quantities when old and charged, and nobody seems to care. > accasionally rupturing You know this is most likely results in a fire right? There is no case where even a slight chance of it happening is safer.

  Can you name any current laptop model that uses cylindrical cells? I haven't encountered any cylindrical cells when opening a laptop in well over a decade.

    My old G771 definitely has them, though that one is like 8 years old or so now? The Gigabyte A5 looks like it might have one, but it's hard to tell without tearing the battery apart. I'm sure lots of gamer laptops still run on 18650s. But yeah they mostly do lipos these days for thinness and weight reduction despite the obvious drawbacks. I wouldn't really ever buy a laptop with a lipo myself, shit's just gonna inflate and split it in half. It's not just laptops anyway, EVs, power tools, flashlights, power banks, li-ion drop in replacement car/ups batteries. Anything that has a lipo has at some point had a cylindrical model too.

      I'm not questioning whether cylindrical cells used to be popular for laptops; they were an iconic part of old ThinkPads. But I've opened up plenty of chunky gaming laptops in recent years from Asus, Dell/Alienware, MSI, Razer and have seen nothing but LiPo batteries. I think cylindrical cells may have genuinely disappeared from the laptop market at this point, unless they're still around in some niche that's significantly more obscure than big heavy gaming laptops. Most laptops these days that opt for a thick enclosure are doing it for the sake of the cooling system, not for the sake of fitting in a thick battery. Edit: I looked at the Gigabyte A5 and agree that it's probably using cylindrical cells. It appears to be a Clevo system, so there were probably other brands reselling as well. But it's not quite a current model (3 year old processor), and the reviews seem to agree that the battery is one of the worst things about the machine, because the capacity is way too small for that class of machine.
