found an old vid we did >10y ago.

we manipulated a single 18650 cell to bypass various safety mechanisms and overcharged it in a safety cage.

this is about the same energy and and energy density your phone has.

the size of the cell is a bit larger than your thumb.

Firefighting reality: many conventional extinguishers can knock down flames but fail to stop #thermalrunaway. Re-ignition is common. Cooling, isolation and prolonged monitoring are essential parts of any lithium-ion fire response plan. 8)

Home storage batteries (and home charging of EVs) present a real threat to the public. It’s not just the threat of a fire that is near impossible to extinguish but the hugely toxic gasses that are produced.

This would be particularly deadly if a thermal runaway like Luton airport carpark fire were to happen in a carpark integral with a large shopping centre.

We have to embrace clean energy technology if we care for the planet but we are not quite there yet with safety despite the frantic virtue signalling of our politicians.

We need a properly engineered solution. Not a political one.

Feuerwehr zu brennenden Elektroautos: Wasser reicht zum Löschen aus

Der Deutsche Feuerwehrverband nahm sich auf seinem jüngsten Bundesfachkongress das Thema Elektroautos vor.
