no, it's an organic solvent like ethylene carbonate/propylene carbonate + some other stuff, which have a boiling point of 230+°C ( 446°F)
heating up batteries is (mostly) fine (under controlled scenarios with known good batteries, spicy pillows can always happen with bad batches) as long as the plastic holding them together doesn't melt
you physically CANNOT make a lithium ion battery with water because lithium reacts with water
from the wikipedia page
Lithium reacts vigorously with water to form lithium hydroxide (LiOH) and hydrogen gas. Thus, a non-aqueous electrolyte is typically used, and a sealed container rigidly excludes moisture from the battery pack. The non-aqueous electrolyte is typically a mixture of organic carbonates such as ethylene carbonate and propylene carbonate containing complexes of lithium ions.[45] Ethylene carbonate is essential for making solid electrolyte interphase on the carbon anode,[46] but since it is solid at room temperature, a liquid solvent (such as propylene carbonate or diethyl carbonate) is added.
as someone who has tried to make a furnace to melt metals, I envy iron age people who could do it successfully (unlike me) with no fancy tools or materials
I've been in Vienna from time to time, and it's pretty good, 365€/year for the pass that gets you buses, trams and subways with unlimited access and no turnstiles anywhere, you just go and enter
Schedules follow work hours and go from a subway every 2 minutes during peak hours to one every 15mins late at night
You have night line buses for weekdays and on Saturday night public transport doesn't shut down
Coverage is good, you almost always have a bus or tram line less then 5 minutes of walking
There are bike sharing places with 20 bikes each ~1km apart and they cost 60 cents for half an hour, or e-scooters in the designed locations which are basically everywhere (but being owned by companies they cost so much more then everything else)
if I try to mention getting something in return for my constant tech support to the whole family I instantly get the "we raised you, how grateful" treatment
ofc if something completely unrelated breaks it's my fault and I'm required to fix it
