Overview | Product Information | Related Products

Silver powder (CAS number 7440-22-4) is a noble metal that exhibits high electrical conductivity (6.3 × 10⁷ at 20 °C). It is commonly used in conductive paste for electronic devices. Silver nanoparticles are employed as antimicrobial agents, owing to their interactions with phosphate-containing compounds within cells and sulphur-containing proteins on membranes.

Recently, silver powder has extended its applications to include batteries. A zinc-air battery incorporating silver powder and graphene oxide as the air cathode demonstrates the maximum current density of 150 mA/cm² at 0.44 V and peak powder of 68 mW/cm² at 130 mA/cm². When a silver powder-modified graphite-composite interlayer used as an anode, it results in a homogeneous formation of Li₁₀Ag₃ with minimal Li residue after discharge.

Silver powder also improves the solar-to-electric efficiency of an N719 dye-sensitized solar cell, enhancing it from 0.98% to 1.2%.
