A Cost‐Effective Supercapacitor Material of Ultrahigh Specific Capacitances: Spinel Nickel Cobaltite Aerogels from an Epoxide‐Driven Sol–Gel Process

Abstract

Nickel cobaltite (NiCo2O4) aerogels, synthesized with a chloride-based epoxide-driven sol–gel process, exhibit ultrahigh specific capacitances (1400 F g−1; see figure), excellent reversibility, and outstanding cycle stability, at a relatively high mass loading of 0.4 mg cm−2.
