We present the superconducting (SC) property and high-robustness of structural stability kagome CsV 3 Sb 5 under in situ high pressures. For initial SC-I phase, its T c is quickly enhanced from 3.5 K to 7.6 then totally suppressed at P ? 10 GPa. With further increasing pressure, an SC-II phase emerges 15 GPa persists up 100 The rapidly increases maximal value 5.2 = 53.6 slowly decreases 4.7 A t...
