The primary benefit of NEU Battery Materials’ separation technique resides in its low energy consumption. By minimizing the use of acids and heat in the separation process, its approach curbs the generation of pollutants and cuts costs.
As the main component of the battery, the electrode is mainly separated by means of crushing, screening, magnetic separation, and fine pulverization in industrial production. To maximize the recovery or reuse of the active material in the electrode, the choice of the separation method is particularly important.
The team proposed that magnetic properties could facilitate the separation and purification of spent battery materials. Their innovation uses a method known as solvent-free flash Joule heating (FJH).
Separators possess a thermal shutdown function; the separator material is thermoplastic, and when the temperature approaches the melting point of the material, its resistance increases by 2–3 orders of magnitude, forming a circuit break to protect the battery. 2.1.2.
