The "80% capacity triggers end of automotive life" threshold is actually somewhat arbitrary — it's where range anxiety starts affecting resale value, not where the chemistry stops working. These packs retain significant energy storage capacity. Second-life applications in stationary grid storage are technically viable and increasingly economical, especially as new-pack costs keep falling. The economics are complicated by the cost of disassembly, testing, and reintegration. Automated disassembly is still in early stages. But the 30GWh of retired EV batteries expected globally by 2030 represents either a significant resource or a significant waste problem depending on whether the infrastructure materializes. Which direction are you betting on?
