Is lithium ion battery technology still not there?

They have an air-driven turbine generator they deploy below the fuselage to provide even more backup. They even had to use it once in test flights when they had a massive console fire in the c*ck pit.

Hello,

there is an important difference. If something goes wrong with the lithium cells in a laptop or phone, it is acceptable to do an emergency shut off of the device. If the lithium cells in a plane overheat, emergency power must be maintained, you cant switch of the cells. Emergency power from these cells must be available until a save landing has been done. The only alternative is to switch to a second or third set of cells.

Hello,

bad idea. These batteries must maintain emergency power in the case all jet engines are not running.

IIRC these things are for complete power loss, the jet engines aren't operating. But the oxygen system for the passengers could be tapped i suppose.

Isn't the passengers' oxygen system there to avoid nasty law suits?

Preliminary:

Power for the safety valves, in case of smoke, was the APU.

The APU shut down but somehow the contactor was still closed upon inspection.
