Synthesis of Phenol–Formaldehyde Resin-Derived Multiporous Carbons with Tunable Micro/Mesoporous Structures through One-Pot Wet Mixing and Nano-CaCO3-Assisted Activation for High-Performance Organic-Electrolyte Supercapacitors
Porous carbons are widely used as electrode materials for electric double-layer capacitors (EDLCs), but their high-rate performance in organic electrolytes is governed more by transport-limited accessibility than by BET surface area alone. Here, a wet one-pot strategy integrating KOH activation with nano-CaCO3-assist...
