Summary: Among the electrode materials of supercapacitors, transition metal oxides, including MnO2, have shown promising properties. However, the low conductivity, agglomeration, and volume change of MnO2 lead to its limited specific capacitance. To address this issue, attapulgite is introduced as a composite material to enhance the electrochemical performance. The ATP-MnO2 composites exhibit higher specific capacitance and better cycle stability compared to pure MnO2 nanoflowers.
