Abstract: A method and system for screening materials for lithium secondary batteries. The method includes receiving information about organic substances, generating a database by storing the information about the organic substances based on a plurality of parameters, and applying a filter to the database to generate output information about a target substance configured to be used in the lithium secondary battery, the target substance selected from the organic substances, wherein the target substance is configured to form at least a part of a low-resistance solid electrolyte interphase (SEI) layer on an anode of the lithium secondary battery.
