Boronium Ionic Liquids for High-Voltage Supercapacitors.

ABSTRACT: Boronium ionic liquids (BILs) are an emergent class of electrolytes with high electrochemical stability afforded by charge delocalization across the cation. BILs are of particular interest for electrochemical energy storage (EES) devices because of their large voltage window. Here, a series of BILs were systematically evaluated as electrolytes in symmetric double-layer capacitors equipped with carbon nanofoam paper (CNFP) architected electrodes. First, the operational voltage window and capacitive properties of supercapacitor cells composed of BILs and CNFP electrodes were evaluated in a two-electrode configuration by using cyclic voltammetry (CV). Then, galvanostatic charge-discharge (GCD) cycling was used to assess the capacitance, energy density, power density, and long-term stability o
