Hydroxyphosphate Powder: A Natural and Sustainable Material
Ideal for stable and sustainable separators in batteries
| |
Hydroxyapatite is a naturally occurring mineral with a formula of Ca5(PO4)3(OH). Hydroxyapatite powder (CAS number 12167-74-7) finds applications in the treatment of dentine sensitivity by promoting the mineralisation process of teeth. It is used as a dental material in dentistry and oral maxillofacial surgery.
Other than its dentistry applications, hydroxyapatite powder is also used as a functional separator in batteries. Hydroxyapatite powder cooperates with cellulose or polymer to form the composite separators. In Zn-ion batteries, a hydroxyapatite-based separator can regulate the desolvation process of the hydrated Zn ions and boost the ion transport. This leads to a fast and uniform Zn deposition and long-term stability over 1600 hours at 1 mA/cm2.
In Li-ion batteries, hydroxyapatite is employed as a filler in polymer electrolyte, demonstrating an ionic conductivity of 1.58 × 10−4 S/cm at room temperature. The battery separators consisting of hydroxyapatite and cellulose exhibit high thermal stability (up to 250 °C) and outstanding flame retardancy.
