I wonder if there's a good strategy that lets you store the dead batteries long-term and wait for the price to get high enough, or recycling technology to bring that cost down enough that it's worthwhile. Storing is is dangerous (search youtube for 'lithium fire'), and takes up space, but I'm sure there's a clever way around that. The only potential for a real bust is if other, better forms of energy storage get invented before your garbage dump's profit margin becomes positive. Or if a new source of lithium is found (isn't it one of the most abundant elements in the universe?).
