Regulating the Porosity and Bipolarity of Polyimide-Based Covalent Organic Framework for Advanced Aqueous Dual-Ion Symmetric Batteries.

[ 40 ] The capacitive‐controlled capacity contribution exhibits an increasing trend as the scan rates continuously increase, ranging from 55.8% at 0.2 mV s −1 to 75.9% at 5 mV s −1 (Figure 3d ), which indicates that the pseudocapacitive‐controlled electrochemical reaction process predominates at high charge‐discharge rates.
