Another Vent-With-Flame Li-ion Story

I particularly like this part about using a TIN pan to contain the mess .

...One of my friends was round and managed to throw the pack into a biscuit tin in the sink, a few seconds later it went off like a roman candle. If he had still been holding it he would only be able to count to 5 for the rest of his life...

Never leave your Li-ions charging unattended!!

... and he took pictures of the smoke. :sick2: Those fumes are potentially lethal, and most guidelines recommend going to the emergency room immediately after breathing smoke from burning li-ion batteries.

Take this thread for example: http://www.candlepowerforums.com/vb/showthread.php?141137-Inhaled-vapors-from-battery!!!

Or this from Energizer:

Fire fighters should wear self-contained breathing apparatus. Burning lithium ion batteries can produce toxic fumes including HF, oxides of carbon, aluminum, lithium, copper, and cobalt. Volatile phosphorus pentafluoride may form at a temperature above
230° F.

Yikes. Inhaling vapors from li-ion batteries is scary stuff. You can't even have the dropsies with li-ions without something going wrong. I do prefer NiMHs as they are one of the safest battery technology. If i had a choice i'd just wire NiMH batteries to my cellphone and use them instead of the li-ion. Maybe not practical but it does make me want to recycle older li-ions i have such as my laptop and my 3 year old cellphone which i had some close calls with it. Until they can design Li-ions safer, NiMhs will continue to be my battery of choice.
