Title: The Innovative Contributions of Jin-Woo Kim in Electrochemical Cell Technology

Introduction

Jin-Woo Kim, an accomplished inventor based in Daejeon, South Korea, has made significant strides in the field of electrochemical cell technology. With a remarkable portfolio of 13 patents, Kim’s innovations are paving the way for advances in the manufacturing of separators and non-woven fabrics, which are crucial in battery applications.

Latest Patents

One of Kim's latest patents is a comprehensive method for manufacturing a separator, which includes several critical steps. The process begins with preparing a porous planar substrate with multiple pores. It then involves coating this substrate with a solution of binder polymer and inorganic particles to form and dry a porous coating layer. The final step applies a binder solution with a higher surface energy than that of the porous coating, resulting in strong adhesion with minimized adhesive use. This separator not only ensures adequate adhesion but also helps in maintaining battery performance.

Another noteworthy invention is a non-woven fabric made from fiber coated with an organic binder polymer compound. This fabric, created by spinning a non-woven forming fiber in a polymer solution, serves as an effective separator substrate for electrochemical cells. The non-woven fabric boasts a pore diameter of 0.001 to 10 μm, providing the necessary mechanical properties while facilitating lithium ion movement. Importantly, it removes the need for a separate adhesive layer, streamlining the manufacturing process.
