Abstract

Notable advancements have been made in the advancement of technologies utilizing flexible screens and sensors. However, the progress in the field of flexible energy storage devices has been comparatively restricted. Research on flexible energy storage electrodes is necessary because of the crucial role of flexibility and stretchability in wearable, biomedical, and portable electronic devices. This study examines the electrochemical characteristics of graphite filaments covered with alloy which possesses flexibility. Electrochemical synthesis of Mn-Cu-based modified graphite was achieved using a deep eutectic solvent at varying static voltages. Analyzed in this study was the electrochemical deposition performance of films in Ethaline deep eutectic solvent, as well as the subsequent cycling of the resultant electrodes in a KOH, Na2SO4 and the mixture of KOH and Na2SO4 electrolytes. The potential window used for this analysis was increased to 1.5 V. The graphite substrate, coated with Mn-Cu through the application of a voltage of –1.9 V, exhibited a length capacitance of 109 mF cm-2 when cycling electrolyte is the mixture of KOH and Na2SO4. The film exhibited extensive surface covering and showed promise for utilization in energy storage applications.
