Unblocked Electron Channels Enable Efficient Contact Prelithiation for Lithium‐Ion Batteries

Contact prelithiation is strongly considered for compensating the initial capacity loss of lithium‐ion batteries, exhibiting great potential for ultralong cycle life of working batteries and the application of large‐scale energy‐storage systems. However, the utilization of the sacrificial Li source...

Description
Summary:Contact prelithiation is strongly considered for compensating the initial capacity loss of lithium‐ion batteries, exhibiting great potential for ultralong cycle life of working batteries and the application of large‐scale energy‐storage systems. However, the utilization of the sacrificial Li source for contact prelithiation is low (
