These are apparently not large EV-type rechargeable lithium batteries, as I immediately assumed.
From the article: "Aricell makes lithium primary batteries for sensors and radio communication devices". A "primary battery" is non-rechargeable; and given the use-cases mentioned I expect each individual battery is fairly small.
Of course, when there are 10s of 1000s of them together that's still a lot of energy to burn.

- kees99 2y agoPrimary, non-rechargeable lithium batteries typically contain metal lithium [0], and are actually more likely to catch fire when mishandled, compared to Li-ion stuff. Specifically, most common Li-ion fires start when overcharged (especially with high current and in cold), and from short-circuits (e.g. when pierced). But only have a very small chance of spontaneously igniting from just disassembly alone [1]. Still non-zero chance, don't open them! Primary/metal lithium batteries, on the other hand, are much more likely to burst into flames when opened. Notably, lithium-iron disulfide (AA/AAA "alkaline replacement") cells are notorious to do that just from air exposure, even if one is very careful to not short/pierce anything.
