Although a high stack pressure (≥50 MPa) enhances solid-solid contacts in solid-state batteries (SSBs), it poses impracticality for commercialization. This work proposes self-pressure silicon (Si)-carbon composite anode that enables stable operation under reduced external (≤2 MPa). The features prestress structure can effectively alleviate the internal and stress simultaneously, which is fabricated with ionic-conductive poly(ethylene oxide) (PEO)/lithium salt-coated carbon nanotubes (CNTs) being compressed by shrinking graphene hydrogel. capillary-driven hydrogel shrinkage generates pressure, compensating volumetric expansion (up to 300%) of Si. creates dynamic interfaces between CNTs/PEO expanding Si, ensuring both mechanical stability ion/electron transport. SSBs this have long cycle life 700 cycles capacity retention 79.2% an organic/inorganic electrolyte without (0 half-cell using sulfide reached was able achieve at lowest 2 MPa pressure. design resolves interfacial challenges SSBs.
