The device provides a way to understand the basic breakdowns, build-ups, and other changes on the electrode surface during operation. This work has implications for energy storage, energy generation, and manufacturing technology. Your Name. Introduction: Electrochemical Systems. Electrochemical systems are devices or processes in which an ionic conductor mediates the inter-conversion of chemical and electrical energy. The reactions by which this inter-conversion of energy occurs involve the transfer of charge (electrons) at the interface between an electronic conductor (the electrode) and an ionic conductor (the electrolyte).
