Title: The Innovations of Soo-Jin Kim
Introduction
Soo-Jin Kim is a prominent inventor based in Daejeon, South Korea. She has made significant contributions to the field of lithium secondary batteries, holding a total of 5 patents. Her work focuses on improving battery performance and longevity, which is crucial in today's technology-driven world.
Latest Patents
One of her latest patents is for a nonaqueous electrolyte lithium secondary battery. This innovative battery design includes an anode capable of intercalating or disintercalating lithium ions, a cathode made with a lithium-containing oxide, and a nonaqueous electrolyte solution. The lithium-containing oxide comprises a lithium nickel-based oxide, while the nonaqueous electrolyte solution includes vinyl ethylene carbonate (VEC) and a mono-nitrile compound. This design addresses the deterioration of charge/discharge cycle characteristics caused by the lithium nickel-based oxide used in the cathode. It also controls the decomposition reaction of the electrolyte, mitigating the swelling phenomenon even when the battery is stored at high temperatures or charged/discharged in a fully-charged state, thereby enhancing high-temperature life characteristics.
Another notable patent is for a non-aqueous electrolyte solution for lithium secondary batteries. This solution includes a lithium salt and an organic solvent, along with a solvent that has a fluoro group and a specific siloxane compound. A lithium secondary battery utilizing this non-aqueous electrolyte solution demonstrates significantly improved capacity recovery characteristics after high-temperature storage and reduces side effects such as swelling.
