Devil A backup that heats, smokes and expel fire? And not works as a backup?

Hi,

FullWings:

I can't see an obvious way to stop the heat bleeding through to other cells - the electrical bonding between them would carry significant flux even if the insulation of the walls was perfect.
Good point! Will think on this.

As it stands at the moment, my personal opinion is that it is possible to have a safe installation of li-ion batteries in an airliner but Boeing have chosen the wrong chemistry together with inadequate safeguards.
I agree.

I agree with the NTSB that fire on board is something that just isn't acceptable, even if you think it could be contained.
Heat, smoke...but even fire! (and result: No backup energy)

Problem is. You need a dependable battery. Thatīs one (perhaps the more important) to switch now back to Ni cd. In the meantime a redesign would restore the confidence.

...even if you think it could be contained.
IMO, unacceptable. But if likelihood is lowered could be a short term "exit" to the stalemate.
