摘　　要：Pre-lithiation methods address the challenges of low initial coulombic efficiency(ICE)and reduced energy density in lithium-ion batteries(LIBs)by adding additional lithium sources to compensate for initial irreversible Li+losses.The direct contact pre-lithiation(DC-Pr)method has garnered extensive attention due to its simplicity,convenience as well as significant effects on the improved cycling durability.Considering the most important factors,i.e.,effectiveness and uniformity,this review focuses on the anode DC-Pr method for LIBs with the lithium sources from Li foil,stabilized lithium metal powder(SLMP),lithium-rich alloys,and physical vapor deposition of lithium metal.After summarizations and discussions,the review overviews the challenges and prospects for DC-Pr methods,aiming to provide guidance for the construction and developments of practical LIBs.
