Water-based hybrid capacitor [Public Suwa University of Science and Technology]

A hybrid capacitor using manganese dioxide as the electrode to solve the challenges of electric double-layer capacitors (EDLC).

This is a hybrid capacitor that solves the challenges of EDLC, specifically "small storage capacity and high installation costs." By using manganese dioxide, activated carbon, and alkaline electrolyte, it achieves the following performance: - High capacity stability, maintenance-free, and usable for long periods - Low risk of ignition and does not contain harmful substances that affect the human body - Ensures sustainability through the use of manganese and activated carbon It can be utilized as a replacement for secondary batteries, as a backup power source, auxiliary power source, or as an energy storage device in non-electrified areas.
