Latest Patents

One of his latest patents involves covalently cross-linked gel electrolytes. These proton-conducting gel electrolytes contain acid immobilized within a covalently cross-linked polymer network. This innovation provides low ionic resistance, minimizes acid stratification, and prevents dendrite growth. The gel electrolytes can be formed from monomers dissolved in concentrated sulfuric acid and subsequently covalently cross-linked between the battery electrodes. Alternatively, they can be formed in water and exchanged into sulfuric acid. The mechanical properties of these gels can be enhanced with the addition of silica powder, silica fiber, or other additives. In some cases, the gel electrolytes are formed in the presence of a conventional silica-filled polyethylene separator or within a low-density fiber mat to provide mechanical reinforcement and controlled spacing between the battery electrodes. This advancement results in increased power capacity of the battery, as the polymer networks can be formed at low concentrations of less than 20% solids.

Another significant patent by Jungseung Kim is for high porosity silica-containing microporous sheets. This flexible microporous polymer sheet features a polymer matrix binding a filler component that exhibits high oil absorption capacity. The polymer matrix includes a polyolefin component and has three-dimensional interconnecting and interpenetrating pore and polymer networks. These networks distribute the bound filler component from one major surface to the other. The microporous polymer sheet achieves between 75% and 90% porosity while containing less than 10 wt. % polyolefin component. Preferred components include ultrahigh molecular weight polyethylene and high oil absorption precipitated silica.
