It seems to me that it could also pose some major problems getting any kind of batteries, from cameras, iPods, phones... what types of electronics these days don't use Li-ion batteries?

Exactly!! Everything uses Lithium Ion, so there is NO WAY they will stop shipping them, despite any remote danger. They are a necessity these days.

Eventually, they'll put some new safety regs in place, like location in plane and container requirements, but our society would grind to a halt without 'em!!

No 'teenage texters', no phone calls in elevators or buses? Perish the thought....I'm getting a Panic Attack just thinking about it!!!!!:ohmy::ohmy:

This is in the news this morning, it could pose some major problems getting e-cig batteries.

FAA issues fire warning for lithium batteries - Yahoo! News

I don't like the fact that the FAA chose not to disclose the temperature at which Li-Ion battereis become thermally unstable....or advise to the proper transportation of Li-Ions...

first off if Li-Ions are going to be taken on an airline whether in checked baggage or a carry on they should be in an appropriate carrier such as:
Cr2, CR123, AA, and AAA Batteries at Inanycase.com: inanycase.com - Memory Card Cases - Battery Cases
or
Carriers

anything that's going to protect the batteries from rattling around, terminals being contacted or shorting....a metal can like in the article isnt really appropriate

second so the info is out there:
Lithium-ion cells with cobalt cathodes (same as the recalled laptop batteries) should never rise above 130°C (265°F). At 150°C (302°F) the cell becomes thermally unstable, a condition that can lead to a thermal runaway in which flaming gases are vented.

LiMN or high drain cells are known otherwise as spinel cells and are more heat tolerant:
Manganese is the newer of the two chemistries and offers superior thermal stability. It can sustain temperatures of up to 250°C (482°F) before becoming unstable.

in either case... even in a cargo hold in the dead of summer I doubt that the temperature in a bag full of clothes gets to 265 degrees farenheit.... it's gotta be either improper transport....or the fact that they're being transported in an unpressurized cargo hold...raising the internal pressure of a battery to a dangerous level...
also I'm guessing that protected versus unprotected batteries play a part... since with a protected battery the physical protection features would kick in:
the circuit interrupt device (CID) opens the electrical path if an excessively high charge voltage raises the internal cell pressure to 10 Bar (150 psi); and the safety vent allows a controlled release of gas in the event of a rapid increase in cell pressure.... A fuse cuts the current flow if the skin temperature of the cell approaches 90°C (194°F).

so the FAA....bad science and crap batteries all around in these tests that they're basing the warning on...

It's not like a government agency has never done anything like that before! ;)

lol right?.... who the heck says let's take a handful of 3/4 charged Li-ion batteries and ship them in a metal drum so they're free to jostle around so the terminals can contact the container....it's like filling your pocket with change and then putting a bare Li-Ion battery in there too....you're going to get a burned leg

Meh. The entire thing reads like a solution looking for a problem.

The batteries, when exposed to a fire, create an increased risk of having a worse fire. In other news, so does jet fuel, which planes carry thousands of pounds of every flight.

I'm personally more concerned with this throw away statement: "There are no fire suppression systems required in the main cabins of cargo or passenger planes."

Because... wtf...

Don't current safety regs say that all Lithium ion batteries should be carried on rather than in checked bags? It's in the article- but not very clearly - that the warnings are related to lithium metal batteries- not lithium ion batteries.

The halon fire suppression systems used in the lower cargo compartments of passenger and cargo planes aren't able to put out fires caused by lithium metal batteries. However, the systems can extinguish fires caused by lithium ion batteries, which are rechargeable batteries similar to the kind used in many cell phones and laptop computers.
I'd rather have no fire suppression system in the main cabin than a halon fire suppression system...

good catch on that Lithium metal versus Lithium Ion bit....I was too caught up in that whole problem looking for some histeria scene that I failed to catch that bit...
