This invention belongs to the field of supercapacitor technology, specifically relating to a molybdenum oxide-molybdenum disulfide@polytannic acid electrode material, its preparation method, and its applications. Using molybdenum foil as the current collector and electrode, this invention prepares a molybdenum oxide-molybdenum disulfide electrode using electrochemical oxidation and hydrothermal methods. A polytannic acid coating is deposited on its surface to prepare a biodegradable molybdenum oxide-molybdenum disulfide@polytannic acid electrode. This electrode is then sandwiched with a biodegradable gel electrolyte and encapsulated with a biodegradable encapsulation material to construct a biodegradable supercapacitor with self-discharge suppression capabilities. By depositing a polytannic acid coating on the surface of the supercapacitor electrode, its self-discharge behavior is suppressed. The polytannic acid coating can prevent parasitic Faraday reactions of impurity ions on the electrode surface and prevent charge transfer, thereby suppressing the capacitor's self-discharge behavior. Simultaneously, the electrode, electrolyte, and encapsulation material can all degrade in simulated body fluids, potentially opening up applications in implantable medical electronic devices.
