The technology focuses on the development of the ideal core/corona structured bifunctional catalysts for the air electrode of metal-air batteries and fuel cells. The proposed core/corona structured bifunctional catalyst has been tested in a rechargeable Zinc-Air battery, resulting in a battery system showing three times capacity of a commercial lithium-ion battery. Over 900 cycles of charging have been achieved at high current for a small catalyst loading.

A prototype has been developed....


The cycle life of the zinc/air battery has been the major hurdle to bringing a zinc/air to market.
