Title: Prussian Blue Analogues as cathode material in low cost aqueous batteries
Affiliation: Aarhus University 

Abstract

In order to increase the use of sustainable energy sources like solar and wind, new solutions in terms of energy storage are needed to overcome their highly intermittent nature. For battery technologies to be relevant for grid-scale storage, the electrode materials must be low cost, environmentally benign, have high energy efficiency and long cycle life. Because of the requirement for cheap electrode materials, the choice of elements are limited to earth abundant transition metals such as iron, manganese, zinc and copper. Prussian Blue Analogues (PBAs) are investigated as cathode material in large-scale, low cost aqueous batteries. PBAs are a large family of transition metal hexacyanoferrates with the general structural formula AXM[Fe(CN)6], where A is a cation and M is a transition metal. PBAs are practically insoluble and are structurally stable towards insertion/extraction of a wide range of ions, providing good cycling capabilities.
