Gnanomat Advanced Materials for SZAB Air Electrodes

By Gnanomat

Gnanomat’s advanced materials were confirmed as competitive bifunctional catalysts in the air electrode of Secondary Zinc-air batteries (SZAB). This technology is already in the development stage mainly due to its limited cyclability, low performance and high cost of the air electrode. The tests carried out in SZAB prototypes using Gnanomat´s advanced materials as bifunctional catalysts for the air electrode showed an outstanding performance in charge and discharge modes. In addition, the tests performed in prototype cells also showed a great stability and cyclability, addressing one of the most challenging drawbacks of this technology. The bifunctional catalysts developed by Gnanomat used in air electrode of SZAB prototypes meet the requirements to be industrially viable products, manufactured following industrial and green protocols using low cost and environmentally friendly raw materials which represents an important advantage compared to the best catalysts in the literature that are based on Nickel and Cobalt metals displaying higher cost and scarcity (e.g. Cobalt is in the list of Critical raw Materials of EU). These results were obtained in collaboration with CIDETEC, a reference center in energy storage research, as an independent third party, and the technology and findings are in process of IP filing.
