Global lithium battery safety and recycling regulation

Lithium-ion batteries are presenting significant safety and regulatory challenges globally. Experts have highlighted the danger of “thermal runaway,” a process where internal short circuits or high temperatures cause self-sustaining fires that are difficult to control. This phenomenon poses risks to waste management systems, as punctured or crushed batteries can ignite during collection, leading to incidents such as garbage truck fires.

In Europe, regulatory scrutiny is increasing. The European Maritime Safety Agency has noted that damaged batteries can release toxic and flammable gases, while the European Commission has initiated infringement procedures against Spain regarding electronic waste directives. Spain has implemented specific regulations for the separate disposal of lithium batteries and is working toward improved traceability through a national registry.

Despite these hazards, the end-of-life battery market is viewed as a critical “secondary mine” for minerals like lithium, nickel, cobalt, and copper. The International Energy Agency predicts the secondary supply of key energy minerals could double by 2040. To manage this, the European Union has established ambitious recycling efficiency targets, aiming for lithium recycling rates of 65% by 2025 and 70% by 2030. While China currently holds approximately 90% of global material recovery capacity, the industry is moving toward more structured collection and safe transport to secure mineral supplies.
