No it's not an H-bomb.
Generally you dispose of lithium batteries by first completely discharging them (0 volts), then put them in a saturated saline solution,
then puncture them. Let them sit in there for a day or so then just throw them away. At least that's what I do...
I just found this article, too. It explains things in more detail.
