Waste lithium batteries mainly consist of five components: cathode, anode, separator, electrolyte, and casing, featuring stable composition and high recyclability.
- Cathode: Contains lithium, nickel, cobalt, manganese, iron and other metal oxides, with the highest recycling value.
- Anode: Mainly graphite with copper foil current collector, providing stable conductivity and energy storage.
- Separator: Polymer material that isolates cathode and anode to prevent short circuits.
- Electrolyte: Lithium salt dissolved in organic solvents, enabling ion transport.
- Casing: Metal or aluminum-plastic film for protection and packaging.
Through standardized dismantling and sorting, high-value materials such as lithium, nickel, cobalt, copper and graphite can be recovered, reducing resource consumption and environmental pollution—an essential part of new energy recycling.
