He has made significant contributions to the field of battery technology, particularly in the development of advanced electrode materials. With a total of 6 patents to his name, Ryu's work focuses on enhancing the performance and efficiency of rechargeable lithium batteries.
Latest Patents
One of Ryu's latest patents is for an electrode material that contains polyvinyl alcohol (PVA) as a binder. This innovation provides an electrode mix for a secondary battery that includes a PVA with a degree of polymerization greater than 2500 and a degree of saponification exceeding 90%. The use of this binder improves adhesive strength between the electrode mix and the current collector, prevents peeling and separation of the active material during charge/discharge cycles, and inhibits decreases in capacity or output power retention rate.
Another notable patent involves a composite binder containing carbon nanotubes for a lithium secondary battery. This nanocomposite binder enhances the conductivity of the anode by reducing the electrical resistance of the binder. It also improves the mechanical properties of the binder, preventing the separation of the anode active material layer from the current collector due to volume changes during charge/discharge cycles.
