Solutions by Application

Separator & Electrode Coatings

• AEROSIL® & AEROXIDE® – High-purity silica and alumina for ceramic coatings that boost separator safety and prevent thermal runaway.

Electrolyte & Additive Systems

• SIPERNAT® – Specialty silica for excellent moisture control and improved electrolyte stability.

• TEGO® SURTEN E– Process additives for optimized electrode slurry dispersion and coating uniformity.

Binder & Structural Components

• POLYVEST® – Functional polymers for flexible binders and sealing solutions, ensuring mechanical integrity and long-term performance.

• VESTOPLAST® - Poly-alpha-olefins offering fixation and bonding in various parts of the Lithium-ion battery, e.g. electrode and separator fixation and insulation.

Battery Recycling

• HYPROX® - Hydrogen peroxide can oxidize or reduce metals such as Co, Mn, Ni, Li, and Fe to aid in their recovery from the lithium-ion battery substrates in hydrometallurgical recycling processes.

• Persulfates – Ammonium and potassium persulfate are used in processes for recovering lithium at the end of a battery’s useful life.
