Abstract All‐solid‐state batteries (ASSBs) are emerging as promising candidates for next‐generation energy storage systems. However, their practical implementation faces significant challenges, particularly requirement an impractically high stack pressure. This issue is especially critical in high‐energy density systems with limited negative‐to‐positive electrode capacity ratios (N/P ratios), where uneven lithium (Li) stripping induces the formation of interfacial voids. study addresses these challenges by introducing anode a novel structural design that operates effectively under practically viable conditions while significantly reducing N/P ratio to less than one. The approach entails integration lithiophilic magnesium (Mg) film beneath thin layer silicon‐graphite (SiGr) active materials. structure facilitates deposition excess Li SiGr during overcharging, which enables stable cycling even at room temperature and low pressure 3 MPa. By mitigating poor contact characteristic ASSBs pressure, simultaneously increasing lowering ratio, advances key electrochemical properties ASSBs.

Abstract Interest in all‐solid‐state batteries (ASSBs), particularly the anode‐less type, has grown alongside expansion of electric vehicle (EV) market, because they offer advantages terms their energy density and manufacturing cost. However, most ASSBs, anode is covered by a protective layer to ensure stable lithium (Li) deposition, thus requiring high temperatures adequate Li ion diffusion kinetics through layer. This study proposes dual‐seed consisting silver (Ag) zinc oxide (ZnO) nanoparticles for sulfide‐based ASSBs. dual‐seed‐based not only facilitates via multiple lithiation pathways over wide range potentials, but also enhances mechanical stability interface situ formation Ag–Zn alloy with ductility. The capacity retention during full‐cell evaluation 80.8% 100 cycles when cycled at 1 mA cm −2 3 mAh room temperature. approach provides useful insights into design multi‐seed concepts which, from mechanochemical perspective, various lithiophilic materials synergistically impact upon interface.
