Latest Patents

Park is named on one patent: “Energy storage device based on nanocrystals including metal oxide rescaled by lithiation and supercapacitor using the same.” The invention describes dispersing transition-metal nanoparticles across a high-surface-area carbon support, then using lithium ions to reduce and further disperse the particles. The resulting metal particles are described as smaller than one nanometer.

According to the patent description, the treated material provides higher capacitance than the metal oxide before resealing. The patent also reports that the supercapacitor can maintain its performance through more than 100,000 cycles, attributing this durability to reduced particle interference.
