Nickel (II) Nanopowder with Particle Size of 8-18 nm

Applied in many research fields including batteries, solar cells, supercapacitor, and catalysis

Overview | Product Information | Related Products

Nickel (II) oxide, CAS number 1313-99-1, also known as NiO, adopts a face-centre cubic crystalline structure. It has been used to produce frits, ferrites, and porcelain glazes. In recent years, nickel (II) oxide finds application as a hole-transport layer (HTL) material in perovskite solar cells. HTL of nickel (II) oxide processes high conductivity of 2.45 × 10-2 mS/cm and strong hole-extraction ability (7.01×10-3 cm2/V⋅s). This HTL layer enables the inverted perovskite solar cell to achieve a powder conversion efficiency (PCE) of 22.62%.

Nickel (II) oxide is also applied in supercapacitors. The supercapacitor fabricated from nickel (II) oxide nanopowder exhibits specific capacitance of 605 F/g at 5A/g and cyclic stability of 500 cycles.

As an energy material, nickel (II) oxide is used as a cathode material in batteries. A paper-based battery featuring nickel (II) oxide powder demonstrates a maximum current density of 1.94 mA/cm2 and power density of 1 mW/cm2.
