CORE STAGE
3 Discharging & Dismantling
Updated 04/2025
Short Description
Depending on the recycling process, batteries may be discharged to eliminate stored energy and prevent safety risks such as short circuits or thermal events—either as a standalone process or integrated into the recycling system. Some companies also discharge batteries before transport to comply with SOC regulations. Depending on the recycling method, batteries may also be dismantled to remove housings and reduce impurities before shredding, while manufacturing scrap like electrode foils can usually skip these steps and go straight to material separation.

Sub-Processes
3.1 Discharging & Deactivating
Discharging or deactivation reduces the stored energy in batteries to prevent short circuits or thermal events during further processing. This can be done electrically, chemically or thermally.
3.2 Dismantling
Dismantling reduces the size of batteries—ranging from pack to cell level—and separates components like housings or the BMS for dedicated recycling streams. This maximizes the amount of relevant material for shredding and improves the quality of the resulting black mass.

Guidelines & Regulations
The Governmental Regulations section outlines key policies and legal frameworks that govern battery production, usage, recycling, and disposal to ensure safety, sustainability, and compliance with environmental standards.
⚠️ Please note: This section does not represent a complete or exhaustive overview of all applicable regulations. It is intended for general orientation only and should not be considered legal advice or regulatory interpretation. For detailed compliance guidance, always consult the official legislation or a qualified regulatory expert.
Regulations
Special precautions and safety measures must be in place for the treatment of waste lithium-based batteries during handling, sorting, and storage. These include protection from excessive heat, water, crushing, or physical damage. Waste batteries must be removed from vehicles in accordance with the End-of-Life Vehicles Directive.
