Electrolyte Effects on the Stabilization of Prussian Blue Analogue Electrodes in Aqueous Sodium-Ion Batteries

Xaver Lamprecht et al.

Summary: Aqueous sodium-ion batteries based on Prussian Blue Analogues (PBA) have the potential to be scalable energy storage systems. This study investigates the degradation processes in PBA electrodes during charge-discharge cycles. It finds that the dissolution of nickel and cobalt is the main cause of degradation, and the nature of the anions in the electrolyte affects the degradation rate, with perchlorate being the most unstable and sulfate the most stable. The study proposes that the dissolution process is initiated by the adsorption of anions during electrode oxidation.
