Patent number: 11905302Abstract: The present disclosure relates to a prelithiation solution and a method for preparing a prelithiated anode using the same. The prelithiation solution and the method for preparing a prelithiated anode using the same according to the present disclosure allow uniform intercalation of lithium ions throughout the anode chemically in a solution via a simple process of immersing the anode in a prelithiation solution having a sufficiently low redox potential as compared to an anode active material. A prelithiated anode prepared by this method has an ideal initial coulombic efficiency and a lithium secondary battery with a high energy density can be prepared based thereon. In addition, the prepared anode is advantageously applicable to large-scale production due to superior stability even in dry air.Type: GrantFiled: December 14, 2020Date of Patent: February 20, 2024Assignee: Korea Institute of Science and TechnologyInventors: Minah Lee, Jihyun Hong, Kyung Yoon Chung, Jin-Yoo Suh, Sang Ok Kim, Hyungseok Kim, Inyeong Kang, Ju Young Jang, Jin Kwan Choi
