20 years is very nice, how recyclable are they after that though?
The process for recycling solid state batteries is more complicated at the moment:
Who cares that’s ages away /s
But really, who cares. Landfills are a negligible amount of land usage and land used for them can be repurposed after closing the landfill. As long as you bury it enough to keep it out of the biosphere the environmental impact of not recycling is negligible. Recycling is preferable for lowering resource extraction sure but as long as its still more resource efficient than a gas car that’s irrelevant.
To me this is the same as oil industry propaganda over wind turbine blades not being recyclable, like oh no it’ll occupy a few cubic yards of a landfill in 15 years, better build a new coal/gas plant instead.
There are companies that claim to be ready to recycle most car batteries, but there are just not many old ones yet
