Ossila M2437A1 is a hydroxyapatite micropowder with an average particle size of 3 µm and a purity above 99.5%. Also known as calcium hydroxyphosphate or tribasic calcium phosphate (HAp), this naturally occurring mineral (CAS 12167-74-7) has the formula Ca5(PO4)3(OH) and comes as a white powder. It is aimed at battery researchers looking for green, sustainable materials.
The powder is typically combined with cellulose or a polymer to build composite battery separators. In zinc-ion cells, a hydroxyapatite-based separator helps control the desolvation of hydrated Zn ions and speeds up ion transport, giving fast, even Zn deposition and stable operation for over 1600 hours at 1 mA/cm2. In lithium-ion systems it serves as a filler in polymer electrolytes, where an ionic conductivity of 1.58 × 10−4 S/cm at room temperature has been reported.
Separators made from hydroxyapatite and cellulose stay thermally stable up to 250 °C and show strong flame retardancy. The material has a melting point of 1650 °C, a calcium content of 27.4% and a phosphorus content of 12.5%. It is supplied in 10 g, 25 g and 50 g packs.
- Fabrication of composite battery separators with cellulose or polymers.
- Functional separators for Zn-ion batteries that regulate Zn-ion desolvation and support uniform Zn deposition.
- Filler for polymer electrolytes in Li-ion battery research.
- Thermally stable, flame-retardant hydroxyapatite/cellulose separators for safer cells.
