What are Per- and polyfluoroalkyl substances (PFAS)?

Human-made chemicals can be found in many everyday products.

These chemicals contain carbon-fluorine bonds, do not break down and can stay in water and soil forever.

They pollute the environment and some harm our health.

PFAS Risks in Li-ion Battery Cells

PFAS can be found in Li-ion battery cells as binders (e.g. PVdF) in electrodes and separator coatings, and additives (e.g. PFBS) in electrolytes

With global LIB production projected to reach ~4 TWh/year by 2030, PVdF demand could surge

~140k ton/yr

Battery Recycling Challenges caused by PVdF

Separating the black mass from the current collectors is the critical step.

PVDF complicates black mass delamination from the current collectors during recycling due to

ineffective dissolution in solvents (e.g. NMP)

formation of toxic gases (e.g. HF, smaller PFAS) during the removal and/or degradation
