Publication number: 20250174712Abstract: A sulfur dioxide-based inorganic electrolyte solution is doped with an iodine compound. A method of manufacturing the inorganic electrolyte solution includes preparing a powder salt by mixing a metal chloride, aluminum chloride and an iodine compound, and synthesizing the inorganic electrolyte solution by injecting sulfur dioxide (SO2) gas into the powder salt. The inorganic electrolyte solution is represented by Chemical Formula 1: M·(AlCl(4-x)Ix)z·ySO2, where M is at least one selected from the group consisting of Li, Na, K, Ca, and Mg, 0<x?1, 0<y?6, and 1?z?2. Reliability and stability of the battery are improved by suppressing growth of dendrites and reducing overvoltage occurring during charging and discharging of the battery by performing pre-treatment of lithium metal using the inorganic electrolyte solution.Type: ApplicationFiled: May 9, 2024Publication date: May 29, 2025Applicants: HYUNDAI MOTOR COMPANY, KIA CORPORATION, IUCF-HYU (INDUSTRY-UNIVERSITY COOPERATION FOUNDATION HANYANG UNIVERSITY)Inventors: Kyu Ju Kwak, Ji Yong Lee, Won Keun Kim, Eun Ji Kwon, Samuel Seo, Yeon Jong Oh, Dong Hyun Lee, Sang Su Lee, Kyoung Han Ryu, Ji Ho Lim, Han Su Kim, Ji Whan Lee, Seong Hoon Choi, Seung Do Mun
