Abstract Silicon (Si) is one of the most promising anode candidates to further push energy density lithium ion batteries. However, its practical usage still hindered by parasitic side reactions including electrolyte decomposition and continuous breakage (re‐)formation solid interphase (SEI), leading consumption active lithium. Pre‐lithiation considered a highly appealing technique compensate for losses. A critical parameter successful pre‐lithiation strategy means Li metal achieve lithiation material/composite at uniform lateral in‐depth distribution possible. Despite extensive exploration various techniques, controlling amount precisely while keeping homogeneous remains challenging. Here, thermal evaporation as novel pure Si anodes that allows both, is, precise control degree deposition surface reported. nucleation, mechanical cracking, ongoing phase changes are thoroughly evaluated. The terms dry‐state wet‐state (without/with electrolyte) revisited. Finally, series electrochemical methods performed allow direct correlation pre‐SEI formation with performance pre‐lithiated Si.

Abstract State‐of‐the‐art carbon coatings are sought to protect high‐capacity silicon anodes, which suffer from low conductivity, large volume change and fast degradation. However, this approach falls short when handling physical–electrical disconnections between shells microparticulate (SiMP) with drastic size variations. Here, a strategy of covalent coating is developed establish robust encapsulation structure. The obtained SiC bonds enable an effectively dynamic connection the electrochemically deforming SiMP sliding graphene layers, preventing evolution gaps shell maintaining persistent electrical connections as well mechanical toughness. As result high structure reversibility, cycling stability thick anodes greatly improved, up areal capacity 5.6 mAh cm −2 volumetric 2564 −3 . This interface bonding effect demonstrates great potential for suppressing deformation involved degradation materials through strategies.
