This invention relates to the field of battery technology, and more specifically, to a solid-state battery cell and a solid-state battery. The solid-state battery cell provided by this invention includes at least one layer of flame-retardant and explosion-proof material. By spatially separating the flame-retardant and explosion-proof material layer and the electrode layer, this solid-state battery cell achieves improved safety of the high-energy-density solid-state battery system without significantly reducing the cell's energy density. Furthermore, the amount of flame-retardant and explosion-proof material added is unlimited and can be arbitrarily adjusted according to protection requirements to achieve the ideal flame-retardant and explosion-proof effect. In addition, this structural design eliminates interfacial side reactions caused by large-area contact between the flame-retardant and explosion-proof material and electrolyte particles, as well as compatibility issues with solvents in the electrode preparation process.
