Abstract

Lithium-ion batteries (LiBs) are essential to modern life, powering everything from small button cells to large-scale energy storage systems. While some used cells can be repurposed in energy storage applications, all lithium-ion batteries must undergo processing at the end of their life (EoL). The variety in shape, structure, and chemical composition of Li-ion batteries poses challenges for recycling. The first step in battery processing is mechanical preparation. This involves evaluating the structure of EoL lithium-ion batteries and designing an effective mechanical process. The process includes multiple comminution steps to liberate materials, separate parts, remove hazardous substances, and classify materials for Black Mass extraction.
