As soon as the energy storage capacity of a battery drops to 80%, the battery is considered unfit for EVs and needs to be retired [5]. In accordance with Bloomberg New Energy Finance, the global capacity of retired EV batteries is predicted to reach 150 GWh by 2025 [6].
During the same period, the demand for grid-scale Li-ion energy storage is expected to grow from 7 GWh (2020) to 92 GWh (2025) to 183 GWh (2030). So, in a realistic scenario, second-life EV batteries could hold enough capacity to provide anywhere from 60%–100% of the demand for grid-scale lithium-ion batteries in 2030.
