Graphene‐based materials, which exhibit large surface areas and superior electrical properties, are promising materials as anodes in lithium‐ion batteries (LIBs). However, the formation of a solid electrolyte interphase (SEI) on surfaces these electrodes causes loss active lithium, leading to severe reduction coulombic efficiency cycle retention. In this study, we combined an electrochemical lithium deposition (ELD) strategy, wherein was inserted into electrode minimize during cycling, with use vertically aligned three‐dimensional (3D) graphene foam. This foam, created via freeze‐casting, facilitated uniform distribution ELD, enhancing utilization. Consequently, preplated foam anode could improve charge transfer stabilize SEI. It exhibited retention 86% at current density 0.5 C for 200 cycles LIBs, is that film‐type foils. Moreover, it enabled easy infiltration polymer through sheets while maintaining its original cell performance liquid electrolyte. Furthermore, higher discharge capacity than foil same negative/positive ratio high‐areal‐capacity lithium–sulfur batteries. Therefore, paper indicates potential high safety, various next‐generation rechargeable
