HF (Hydrofluoric Acid) Scavenging Glass
During battery production, even small amounts of residual moisture can lead to extremely corrosive hydrofluoric acid forming in battery cells because of violent reactions between fluorine and water. SCHOTT HF Scavenging Glass cuts out the reaction, protecting a variety of components and preventing short-circuiting.
In lithium-ion batteries, HF scavenging glass is a reliable additive for passivating HF. It can be added directly to the anode or cathode. For batteries with high-energy density, a ceramic-coated separator is used to increase safety. These materials can be partially replaced by the glass particles. In addition, the glass has the advantage of being less abrasive than processing machines.
HF scavenging glass also provides reliable protection against HF-induced corrosion and degradation in supercapacitors and electric double-layer capacitors (EDLC).
In other applications, the material can intercept harmful HF and bind reliably.
