Abstract

Recently, aqueous metal-ion batteries have attracted significant attention, as they can provide rather efficient and safe solutions with regard to large-scale renewable energy storage applications. However, better fundamental understanding of the electrode and electrolyte materials for these devices is necessary to advance their performance. The research methodology for well-known types of batteries, such as lithium-ion batteries, relies on numerous available cell designs and protocols. Fundamental research in the field of aqueous metal-ion batteries, on the contrary, still requires the development of new, original, and versatile cells as well as procedures to improve the efficiency and informative power of experiments. In this work, a concept for the research cell design dedicated to the aqueous metal-ion batteries is presented, enabling advanced electrochemical characterization of model electrode materials (including the mass changes of the active electrodes). Electrodes based on Prussian blue analogs, which are state-of-the-art electrode materials for aqueous Na-ion batteries, are used to demonstrate the concept.
