Herein, we present an integrated-chainmail electrode that features dual-level chainmail structure with graphene encapsulating nickel foam (Ni@NC foam) to enhance H₂S electrolysis. The electrode comprises a primary chainmail, formed by graphene coating on the surface of nickel foam, and a secondary chainmail, created by graphene encapsulating nickel nanoparticles. This integrated-chainmail structure significantly enhances both the activity and stability of nickel foam, which delivers an industrial-scale high current density exceeding 1 A cm⁻² at 1.12 V versus reversible hydrogen electrode, above five times higher than nickel foam. Moreover, the Ni@NC foam remains stable over 300 hours of test, demonstrating a lifespan at least ten times longer than nickel foam.
