Composite Ti3C2Tx-carbon nanotube electrodes with high active mass for supercapacitors

Pure Ti3C2Tx and Ti3C2Tx -multiwalled carbon nanotube (MCNT) anodes with 35 ​mg ​cm−2 active mass (AM) are prepared. The 90%Ti3C2Tx-10%MCNT electrode shows the capacitance (CS) of 1.78 F cm−2 for 2 ​mV s−1 cyclic voltammetry sweep and 1.95 ​F ​cm−2 for a constant current discharge at 3 mAcm−2 in 0.5 ​M Na2SO4 aqueous medium. The CS of the Ti3C2Tx-10 MCNT anode significantly exceeds the literature results for other Ti3C2Tx anodes. The …
