Lithium ion batteries have been recyclable for a while now-- Best Buy has receptacles for used ones. It's been slow to get off the ground because virgin production is still rather cheap.
There is no process for recycling /automotive/ lithium ion batteries, but that's because their use is so recent--the first commercially available lithium ion EV (Tesla Roadster) wasn't released until 2008. However, EV batteries are essentially the same as commodity lithium ion batteries (e.g. stacks of 18650 cells that you can buy on Amazon), and those have been recycled for a while.
