Maybe better disposal practices. Regulations standardizing batteries would also do a lot of good.

But really, we simply need a lot of virgin batteries regardless because we don't have enough. Recycling and disposal will only really take off once the market is mostly saturated (which we don't appear to be anywhere near).

I'd also point out that modern LiPo batteries are 90% recyclable with no special techniques needed. That's because by weight, the batteries are mostly iron and nickel. Recycling them is really as simple as just melting them down. It only gets tricky if you want to collect the lithium, silicon, and other trace materials (and there are already recycling plants that are handling that).
