  • Polarizable electrode for electric double layer capacitor
    Patent number: 10186385
    Abstract: The present invention provides an electrode for an electric double layer capacitor comprising high energy density, low degradation of electrostatic capacitance and resistance with passage of time even using under high voltage, i.e., excellent long-term reliability. The electrode for the electric double layer capacitor comprises polarizing electrode materials containing porous carbon particles, an auxiliary conducting agent, tungsten oxide powders, and binders; conductive adhesive containing a conductive material and a poly-N-vinylacetamide (PNVA)-based binder; and a sheet current collector.
