Front Cover: Enhancing the Capacitance of Poly(Heptazine Imide) Electrodes in Aqueous Electrolytes via Hybrid Material Design (Batteries & Supercaps 2/2026)

Year: 2026

Type: paratext

Abstract: The Front Cover illustrates the incorporation of potassium-containing poly(heptazine imide) (represented as triangles) into the pores of mesoporous carbon (hexagons). The resulting hybrid material exhibits higher electrical conductivity and a larger specific surface area than bulk ionic carbon nitride. This hybrid design enables the investigation of electric double-layer formation and interaction of K+ from the electrolyte at the PHI/electrolyte interface without the limiting effects of resistance.
