I just measured the steel with my slide gauge. 2mm! Thats quite fat i guess.

Yes, choose carefully where you aim the vent. Li-ion fires generate huge amounts of flammable gases, so it may amount to a monster flamethrower that would make Elon's Musk's look like a toy.  For some numbers, here it is claimed that they produce 330L/kWh of flammable gas (p. 57), and it is recommended to have a forced ventilation rate of 0.32 cfm/kWh (p.48).

  Read the pdf. The container sized fire storage looks like a hell on earth occurrence Big Grin .   Maybe they should adopt the fireworks
 
   storage with high earthen walls to prevent fire radiating to adjacent containers.

Large pack (powerwall) fires needn't be so bad if the pack is properly designed, e.g. see here for a test on a g2 Tesla powerpack. But that's using state-of-the-art tech to improve safety (most of which - alas - is currently impossible to emulate in DIY powerwalls, e.g. tweaks to cell chemistry, separators, highly customized BMS, etc).

Promatec or vermiculite sheets.
From both sheets you can easy make a chimney to the outside.
Both materials are very fire proof and very good insulating.
As mentioned before: a proper designed power wall is very safe--->fuses on each level.
If i remember correctly, Korisan made a topic about this, from cell level fusing up to your solar panels or generator.
For cell level i strongly recommend glass fusses!
Best, Igor
