Solutions de recyclage pour les matériaux de séparation des batteries au lithium en fin de vie

When you recycle separators, their thermal and mechanical properties directly affect your choice of process. Low melting points increase the risk of shrinkage during high-temperature steps. The films are also very thin, often less than 25 micrometers, which makes them prone to static buildup and sticking to other materials. Without proper control, these properties reduce efficiency and increase maintenance time for your equipment.

You will need to manage contamination before you can reuse the material. Used separators often contain electrolyte salts like LiPF₆and solvents that can release harmful gases if heated too quickly. They may also carry small amounts of cathode or anode particles, making mechanical separation less effective. If you remove these contaminants early, you can increase both the purity and market value of your recovered materials.
