They can and might.  They can also burst into flames when just being 
used.  Mine did.  If you are going to use them, I'd:

1.  Do it outside

2.  Don't do it where you could start a range or forest fire

3.  Have a way to get rid of it quickly [i.e. some way to grab and fling it]

4.  If it does catch fire, the fire will be hot.  It will be hotter if 
you put water on it.

5.  For Pete's sake, *don't build it into your radio!*

There are some other Li-based technologies out now that might be safer. 
  I don't think I'll get another Li-Poly.  It was kind of pricey too.

YMMV
