This review summarizes and evaluates the prelithiation methods of SiOx anode, providing guidelines for battery manufacturing and discussing the unresolved issues and development direction for industrial application.
SiOx anode with high energy density and superior stability is expected to meet the demand of the rapidly developed electric vehicles' market. And the prelithiation strategy is proved to be crucial for solving the low initial columbic efficiency that severely limited the practical full-cell energy density. In the past decades, various prelithiation methods have been extensively explored. And a comprehensive evaluation aiming at the scale-up application is highly deserved and urgent. In this review, combining the existing battery manufacturing process, the reported prelithiation methods are roundly summarized and re-evaluated based on the capability, control accuracy, environmental stability, uniformity, cost, safety, and compatibility, which provides guidelines for selecting appropriate prelithiation methods in different application fields. Furthermore, the unsolved issues for the manufacture techniques or instrument and the development direction toward industrial application are discussed.
