Glad you weren't hurt. Anything in the first column of the periodic
table are very reactive, starting with H for Hindenburg. I had a little
Li-Poly RC battery burst into flames on our deck table when it was
powering my KX1. Fortunately, I had it external on a little pigtail and
I could fling it over the rail onto our gravel driveway.
I believe the Li-Poly's are the least stable, followed by the Li-ion,
and then LiFePO4. I charge any Li chemistry battery outside in a steel
bucket using my solar panel, and I'd never put one inside my radios. Of
course we have 2 laptops, two Kindle Fire's, and two Samsung Galaxy 5
phones, all with internal Li-ion batteries and none of those have burst
into flames ... yet.

Just a quick note to affirm the need for caution around Lithium-Ion
battery packs.
Today I was charging a new 12 volt Li-Io battery pack. Fist time being
charged. I was using a specialized automatic Li-Io charger.
Nonetheless, the battery pack exploded with an incredible force, blowing
items off my workbench within 2 feet of the explosion. The burn area on
my workbench exceeds 12 inches. If I hadn't been wearing safety
glasses, I'm sure my eyes would have been badly affected. The sound
level was at least equal to a 44 magnum. My facial hair has been burned
and there are numerous particles embedded in my skin, walls and table.
The furthest piece, embedded in ceiling, is at least 10 feet from the
ignition point. About 2 ounces of C4 would perform about the same.
