solid-state Li-S batteries. By hybridizing two-dimensional carbon nitride and N-doped graphene to form CNG with a very high N content, argyrodite decomposition is largely suppressed, which computational and experimental studies show occurs through strong Li-N binding at the solid electrolyte-sulfur host interface. We propose this inhibits the initial oxidation of argyrodite in the indirect process, kinetically limiting Li-ion extraction, and shifting the potential for sulfide ion conversion to sulfur in the first step. This improves SSSB cycling performance by diminishing the build-up of insulating decomposition products at the interface, unlike experienced by carbon materials such as VC and NG. The CNG sulfur
