Coral Anode - WT Series

This series of products possesses a specific surface area far exceeding that of conventional foam metals and is exclusively applicable to anodes. Employing an in-situ growth method, the LTH (triple-layer hydroxide) catalyst is cultivated upon the foam nickel surface. This catalyst exhibits strong binding affinity, withstands alkaline solution erosion, and forms a coral-like structure. This significantly increases active sites and reduces the oxygen evolution potential by 450 mV. The hydroxide catalyst remains unaffected by anode corrosion, ensuring extended longevity.

Product Description:

This anode employs a growth method whereby LTH (triple-layer hydroxide) catalyst is grown onto a foam nickel substrate. The catalyst exhibits strong adhesion, withstands alkaline solution erosion, and forms a coral-like structure that substantially increases catalytic active sites. The hydroxide catalyst remains unaffected by anode corrosion, ensuring extended service life.

Application Cases:

An AEM client has operated this electrode series continuously for one year in a 100 standard cubic metre tank under conditions of 12,000 A/m² and 1M KOH alkaline solution concentration.

An ALK client has installed this electrode series in a 1,000 standard cubic metre tank, with planned operating conditions of 4,000 A/m² at -1.68V.

Product Application:

Primarily employed as hydrogen-generation electrodes, these products may also serve as positive electrode plate materials for nickel-metal hydride rechargeable batteries, specialised filtration media, catalyst carriers, thermal dissipation materials, damping materials, and sound-absorbing materials.
