Electrochemical conversion technologies are pivotal in the shift towards a sustainable and renewable energy future. Consequently, as the energy transition progresses, moving away from fossil fuels to renewable energy systems, there is an increasing interest in and implementation of for example batteries, fuel cells, and electrolysis. This trend underscores the need to optimize the performance of these electrochemical conversion technologies and address limiting factors such as, for example, lifespan.
Using EQCM-D to gain insights into electrochemical reactions on fundamental and applied levels
One method that can be used to support the development of these technologies is Electrochemical quartz crystal microbalance with dissipation monitoring, EQCM-D. EQCM-D couples electrochemistry with QCM-D and is a powerful tool for studying various aspects of electrochemical reactions on both fundamental and applied levels. It can for example be used to study relevant processes that occur on the electrodes of electrochemical energy conversion technologies. In battery development, EQCM-D can be used to study the formation, buildup, and physical properties of the solid electrolyte interface (SEI) layer that forms during operation in many different battery chemistries. In fuel cells, the method can be used to follow the processes of dissolution and corrosion during electrochemical operation and investigate the impact of potential and other parameters on electrode degradation. And, in electrolytic cells, EQCM-D can be used to measure electrode stability to aid the development of new electrode materials and to support a better lifetime.
Webinar introducing the energy transition and key electrochemical energy conversion technologies
We had the privilege to host a webinar by Prof. Björn Wickman, Chalmers University of Technology on the topic of Electrochemical energy conversion studies using EQCM-D. In this webinar, Prof Wickman, who has about 20 years of experience in electrochemical energy conversion research, introduced the energy transition and the most important electrochemical energy conversion technologies. He also took us through a set of examples of how EQCM-D can be used to give further insights into the processes that occur on the electrodes of batteries, fuel cells, and electrolytic cells.
