HF (Hydrofluoric Acid) Scavenging Glass
Extending the life of lithium-ion batteries and the preservation of their capacity is a major challenge in the development of ever more efficient battery systems. Hydrofluoric acid (HF) absorbent glass powder from SCHOTT is capable of permanently binding hydrofluoric acid and permanently preventing its damaging effect on the cells.
Anti-corrosion powers
When using standard conducting salt LiPF6 in electrolytes, even small amounts of H2O impurities may lead to a severe drop in cell capacity. This degradation is caused by the formation of HF. SCHOTT’s special glass frit binds fluorine, preventing aggressive acids in the cell and therefore avoiding an attack on the sensitive electrode materials, which would lead to reduced lifetime and premature capacity drop and gas formation.
Increasing battery longevity and safety
In addition to extending the lifetime and preserving capacity, SCHOTT HF Scavenging Glass can also help increase the safety of your cell.
Temperature resistant and electrochemically stable
HF-absorbing glass from SCHOTT is a purely inorganic additive which is electrochemically and thermally stable in the cell. Unlike most glasses, it's not attacked by fluorine-containing electrolytes because of its special composition. Interactions with other cell materials are not known.
