Abstract

The technology of harvesting energy wasted in daily life is becoming increasingly important for sustainable energy production and climate change. In this study, we investigated an electrochemical energy harvesting system using blue energy generated by the movement of electrodes. We observed that energy could be harvested based on the electrification phenomenon that occurs when an electrode comes into contact with an electrolyte, particularly when the electrode is modified with a self-as-sembled monolayer (SAM) containing the fluorocarbons. The static charges, which are generated by electrification based on the energy level difference between the electrode and the electrolyte, could be transferred to an external circuit. Additionally, we discovered that structural features of SAM molecules are related to the efficiency of energy harvesting, including the number of fluorocarbons. This system successfully powered an LED, proving the practicality of electrochemical harvesting using blue energy. The results suggest the potential for developing more efficient and high-output energy harvesting systems through the application of various SAM molecules.
