Direct Structure–Performance Comparison of All‐Carbon Potassium and Sodium Ion Capacitors

Abstract A hybrid ion capacitor (HIC) based on potassium ions (K+) is a new high‐power intermediate energy device that may occupy a unique position on the Ragone chart space. Here, a direct performance comparison of a potassium ion capacitor (KIC) versus the better‐known sodium ion capacitor is prov...
