D6.6 Dismantling and recycling Report - Abstract

In Deliverable D6.5, we evaluate the state of charge and ensure that safe conditions are met for handling batteries, prioritizing the safety of workers.
This deliverable outlines a rapid dismantling procedure aimed at enabling second-life reuse and/or the recyclability of components, all while ensuring safety, high efficiency, and productivity.

  1. Preparation for Dismantling: To achieve a high gravimetric recovery rate with a cost-effective process, we have based our approach on a non-destructive method for dismantling the external cover and connectors of the battery pack, preserving its initial size, shape, and functionality for potential reuse. As a result, we recover up to 30% of the total weight of the pack and modules, consisting of non-electrochemical components.
  2. Dismantling Process: The subsequent steps focus on the dismantling of the full battery elements, executed in the following sequence:
    a. Prior to opening, the modules will be stored in Vermiculite boxes to avoid accidental short circuits during mechanical cell opening.
    b. The modules will be dismantled, and the cells will be carefully inspected. C. Cells that are unsuitable for second-life applications will be recycled to recover valuable materials, including the casing, electrodes (including metal foils), separators, and any other polymers.
  3. Recycling Rates: The dismantling and recycling processes are designed to maximize the recovery of critical materials. Initial results indicate that the overall recycling efficiency is aligned with the EU's Battery Directive targets, with an estimated recovery rate of up to 70% of the battery’s total mass by 2030. This demonstrates our commitment to meeting the EU’s recycling efficiency and material recovery targets for cobalt, nickel, lithium, and copper.
    This approach not only supports the EU's regulatory framework but also aligns with sustainable practices by reducing waste and enabling the recycling of high-value materials essential for future battery production.
