Yes, but not from Apple any longer.
1. Send it to a third party service center. This will be a bit cheaper than the Apple route, but you'll have to do some research on which place to send it to. A Google search for "iPod battery replacement" should give you a number of results to work with.
2. Purchase a replacement battery online and use the appropriate guide over at http://www.ifixit.com/ to walk you through the procedure of swapping out the battery. I would not recommend this route unless you consider yourself handy with repairing small electronics.
