BATTERS, the database on Life Cycle Inventories of batteries.

A database designed for end-of-life recycling processes and recycled materials for different regional locations..

Découvrez BATTERS, notre nouvelle base de données !

In July 2023, the European Regulation (EU) 2023/1542 introduced the obligation to declare the carbon footprint for each electric vehicle battery model starting from February 2025. From August 2028, documentation will also need to indicate the percentage of recycled cobalt, lithium, and nickel in batteries. However, existing databases for LCA need to be improved in terms of recycling.

To address this need, WeLOOP has developed the BATTERS database, which compiles Life Cycle Inventories (LCI) of recycling processes specific to electric vehicle batteries. It allows the calculation of the carbon footprint of batteries in compliance with the regulation.

LCI available for purchase in the database

The LCIs are configured and can be adapted to different regional locations/Black Mass compositions/allocations.

Recycling processesRecycled materials
Black Mass preparationLithium salts
Hydrometallurgy (solvent and precipitation)Nickel salts
Pyrometallurgy + hydrometallurgyCobalt salts
Direct recycling (laboratory scale)Copper salts

Types of Life Cycle Inventories (LCI)

The configured LCIs in the database are available in both aggregated and disaggregated forms:

Custom Life Cycle Inventory (LCI) (unit data): Only elementary flows are available; the data could only be used to obtain impact assessment results. One LCI covers one recycling process or one recycled material for a specific regional site.

It is possible to access the subprocesses and parameters to verify various elements or make modifications. A fully disaggregated Life Cycle Inventory (LCI) requires an active licence for the underlying data (e.g., Ecoinvent). One LCI covers one end-of-life recycling process or one recycled material for a selected regional site.

→ The aggregated/disaggregated Life Cycle Inventories (LCIs) are only valid for the Black Mass used as the basis for constructing the data. This Black Mass was primarily composed of NMC batteries. The datasets could be used as a substitute for other Black Mass compositions with a marginal deviation (e.g., a minor content of LFP). However, the data could not be adapted to different Black Mass compositions.

Specific Life Cycle Inventories (LCIs) are developed based on the composition of your Black Mass: You provide the composition of your batteries' Black Mass; we create a specific dataset valid for that composition. These data are parameterised and can be adapted to different regions and/or allocations. The feasibility of developing a custom LCI is determined by our team.
