Frequent Pitfalls in the Characterization of Electrodes Designed for Electrochemical Energy Conversion and Storage

Focus on the importance of energy conversion and storage boosted research interest in various electrocatalytic materials. Characterization of solid-liquid interfaces during faradaic and non-faradaic processes is routinely conducted in many laboratories worldwide on a daily basis. This can be deemed as a very positive tendency. However, careful insight into modern literature suggests frequent misuse of electroanalytical tools. This can have very negative implications and postpone overall development of electrocatalytic materials with the desired properties. This work points out some of the frequent pitfalls in electrochemical characterization, suggests potential solutions, and above all encourages comprehensive analysis and in-depth thinking about electrochemical phenomena.
