Latest Patents

Jihyung Han holds a patent titled "Methods and apparatus for controlling electrodeposition using surface charge properties." This patent explores how surface conduction in porous media can drastically alter the stability and morphology of electrodeposition at high rates, exceeding the diffusion-limited current. His findings reveal that above the limiting current, surface conduction inhibits growth in the positive membrane, leading to irregular dendrites, while enhancing growth and suppressing dendrites behind a deionization shock in the negative membrane. This discovery contradicts traditional quasi-steady 'leaky membrane' models and emphasizes the importance of transient electro-diffusion or electro-osmotic dispersion. The implications of his work suggest that shock electrodeposition could be utilized for high-rate recharging of metal batteries or the manufacturing of metal matrix composite coatings.
