When?
A lot of people are getting 10 years out of a pack down to about 80% capacity.
With careful management that same pack can run at around 80 percent for.. a long time. Cells start becoming dangerous and getting cut out of the circuitry, a 60% lithium battery isn't really a thing, they come in full, worn out, and dead.
20 years maybe? So after 30 years we recycle them.
Edit to add: a use pattern like this is ideal from the perspective of recycling. When you're taking a hundred tons of battery out of commission at once, there's incentive to be thorough.
- hedora 4y agoI read lithium ion capacity follows an exponential decay curve. Each subsequent loss of 5% takes twice as long, or something. My EV has an 8 year battery warranty, and warranty claims on the ones sold 8 years ago were never a common thing (to the point that no one knows what a replacement battery would cost). I'm guessing the rest of the car will fall apart around the battery pack, which will then be repurposed for grid storage or something.
