The recycling of electric vehicle (EV) batteries primarily involves two methods: Cascade Utilization and Disassembly Recycling.
After retirement, EV batteries undergo residual capacity testing. Batteries with remaining capacity above 80% can be repaired and upgraded to enhance their performance. Batteries with remaining capacity between 20% and 80%, while no longer suitable for their original automotive purpose, still hold value for lower-performance applications like low-speed electric vehicles or energy storage. These batteries are therefore suitable for cascade utilization based on specific requirements. Batteries with remaining capacity below 20% are directly scrapped and processed via disassembly recycling.
1. Cascade Utilization
This refers to the process where retired EV batteries, either as complete packs, modules, or individual cells, are repurposed for applications with lower performance demands than EVs. Examples include energy storage power stations, solar-plus-storage systems, communication base stations, and low-speed electric vehicles.
Cascade utilization not only effectively reduces pollution from lithium-ion batteries and minimizes resource waste but also enhances the battery’s overall value. It maximizes lifecycle value, lowers costs for related industries like electric vehicles and energy storage, and promotes the development of new energy vehicles.
2. Disassembly Recycling
This involves processes like physical recycling, hydrometallurgy, or pyrometallurgy to recover and reuse valuable materials such as lithium, cobalt, nickel, manganese, aluminum foil, and copper foil from retired EV batteries.
Concise Meta Description
Explore the two core methods for recycling retired EV batteries: Cascade Utilization for batteries with remaining capacity (repurposing in less demanding applications) & Disassembly Recycling for end-of-life batteries (recovering valuable metals). Learn how this maximizes lifecycle value, reduces waste, and lowers costs for a sustainable battery ecosystem.
