Protein-Tannin Organic Polymer-Based Oxygen-Enriched Graded Porous Carbon as a Cathode for Metal-Ion Hybrid Capacitors

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: March 1, 2025

Metal-ion hybrid capacitors represent an innovative class of electrochemical energy storage systems. However, made from traditional carbon-based materials struggle to simultaneously achieve both high specific capacity and long-cycle stability. A hierarchical porous carbon material with optimized pore structure was synthesized using pig kidney proteins tannic acid as precursors, employing cross-linking polymerization carbonization activation strategies. The as-synthesized sample features exceptionally surface area abundant porosity, which efficiently accommodate the adsorption transport solvated zinc magnesium ions. zinc-ion capacitor (ZHC) achieved a reversible 221 mA h g–1 at 0.2 g–1, while magnesium-ion (MHC) delivered 132 under same conditions. Additionally, DFT calculations revealed critical influence size on metal ion storage. In 2 M ZnSO4 aqueous electrolyte solution, when 1.13 nm, ions exhibited highest energy. contrast, in 0.4 (MgPhCl)2-AlCl3 organic electrolyte, 2.29 nm This study provides important theoretical insights into designing ZHCs MHCs.
