An expansion chamber in the supercapacitor lid absorbs pressure from adsorption heat, preventing electrolyte boiling during faster filling.
A gradual hole-density transition between perforated and solid foil regions cuts boundary strain, suppresses deformation, and preserves tensile strength.
Interchangeable busbar sets let one MMC switching cell base module support half-bridge or full-bridge layouts across current ratings.
A projection-through-hole current path and one-piece insulator improve battery terminal sealing reliability while simplifying part shapes.
An annular-groove mold structure limits resin flow during battery terminal insert molding, keeping terminal top surfaces burr-free for busbar connection.
Metal magnesium oxygen reduction and molten salt sintering raise tantalum powder breakdown voltage while limiting capacitance loss.
