摘要

An cationic surfactant of Hexadecyl Trimethyl Ammonium Chloride (HTAC) are used to modify morphology of MnO by direct electrodeposition. The deposited nanocomposites of MnO : HTAC are composed of nanosheets. The manganese dioxide has shown the highest specific capacitance of 350.02 F/g. Specific surface area of the nanocomposites of MnO : HTAC at surfactant concentration below 50 mM is larger than pristine MnO by BET analysis, which results in that the specific capacitance of nanocomposites of MnO : HTAC is larger than pristine MnO. The MnO : HTAC nanocomposites show better cycles performance of charge/discharge than pristine MnO, because the alkyl chains of cationic surfactants on surface can delay the dissolving of MnO materials in electrolytic solution during cycles. By use of HTAC surfactant, both of the specific capacitance and stability for charge/discharge circles of MnO electrode materials are highly improved.
