For the sake of recycling electrolyte of a polymer Li-ion battery, the salts like LiPF6 will be recycled with CO2 supercritical extraction method.
But how can we preserve the volatile organic solvent carbonates to be used again, as these solvents start evaporating as soon as a cell is opened?
Titus Sobisch
Ethylene carbonate is solid at room temperature, propylene carbonate is also very polar and certainly not volatile.

Thank you Dr. Titus Sobisch for your insightful reply. EC and PC will be easier to handle then. Can you please devise some ways to preserve more volatile solvents, like DMC, EMC?
