Nanoporous-Si composite anodes with different dispersibility were prepared to compare the electrochemical performances of sulfide-based all-solid-state lithium-ion batteries.Ball-milled anode with higher dispersibility exhibited the capacity retention of 80% at 150th cycle.The structure and composition were accurately analyzed using field emission scanning electron microscope with energy dispersive x-ray spectrometer.The both of the pores in Si particles and the elastic deformation of solid electrolyte effectively relieved the stress derived from the volume change of highly dispersed nanoporous Si,resulting in the high capacity retention.
