Nitrogen-doped carbon derived from composite of phenolic and amino foam: Effect of synthesis processes on physicochemical properties and super-capacitive performances

Three-dimensional honeycomb-like hierarchically structured carbon nanosheets from resin for high-performance supercapacitors

“…To further investigate the electrochemical performance of RTK-3, symmetrical supercapacitor (SSC) devices were assembled using two identical electrodes in two different types of aqueous electrolytes (6 M KOH and 1 M Na 2 SO 4 ). For the two-electrode device, the C cell (F g −1 ), E (W h kg −1 ), and P (W kg −1 ) values were calculated using the following eqn (2)–(4): 15,16 C cell = I Δ t / M Δ v E = C cell Δ v 2 /2 × 3.6 P = 3600 E /Δ t …”
