How Much Heat Can A Battery Take?

I need to shrink wrap sets of AA lithium batteries for a radio project. Can I safely heat the shrink wrap with a hot air blower, without harming or causing the batteries to explode?

Absolutely. Heat shrink covering has a very low thermal mass, much lower than the batteries. You can hit it with a heat gun and it will shrink up tight long before the batteries get more than warm to the touch. As long as you don't keep cooking them for an extended period of time it will be fine.
