Toward Higher Prelithiation Degree of High‐Capacity Si‐Based Anodes via Physical Vapor Deposition: Impact on Homogeneity and Performance

Lithium Ion Batteries Incorporating lithium directly on the anode is a possible prelithiation strategy to compensate capacity losses in a lithium ion battery. Physical vapor deposition (PVD) is regarded as beneficial due to a homogenous lithium distribution. However, it is only valid for low degree of prelithiation (DOP) while high DOPs limit the PVD technique, as even Li agglomerates can emerge.
