Tricobalt Tetroxide (Cobalt Oxide)

Tricobalt tetroxide is used as a precursor for the synthesis of lithium cobalt oxide (LiCoO2) cathodes and as a high-capacity transition metal oxide anode material in lithium-ion batteries.

Cobalt oxide is fabricated into high-purity sputtering targets for the deposition of thin films used in magnetic recording media and electrochromic devices.

Co3O4 is frequently synthesized as nanoparticles or nanowires for use in heterogeneous catalysis, gas sensors, and supercapacitors due to its high surface area and redox properties.
