The active carbon materials (ACs) derived from cotton stalks were prepared by two-step synthesis method used the activators of KOH and mixed KOH and K2CO3.XRD,raman spectra,SEM,nitrogen adsorption-desorption isotherm were employed to analyze the structure and morphology of samples.The electrochemical properties were monitored with the cyclic voltametry and charging-discharging test.Surface chemical analysis was performed by thermogravimetry analysis coupled with mass spectrometry (TG-MS).Comparing with AC activated with KOH,the prepared sample with mixed KOH and K2CO3 displayed high electrochemical performance.
