Can you get rechargeable lithium batteries in AA sizes?

I have got a speedlite flash that consumes lots of batteries. I am looking for some heavy duty batteries. One of my friends told me that lithium batteries are the best for such purpose but they have one drawback. Do these batteries come with rechargeable property? If yes then can you get rechargeable lithium batteries in AA sizes? I would really appreciate your information about my query. Thanks.
