MnCoP/(Co,Mn)(Co,Mn)(2)O-4 nanocomposites were prepared by hydrothermal + annealing + phosphating treatment method and their electrochemical properties were investigated, systematically. Aqueous MnCoP/ (Co,Mn)(Co,Mn)(2)O-4//active carbon asymmetric supercapacitor demonstrate the capacitance of 74.14 F/g at 0.1 A/g and good rate performance and cycling stability(maintained 85.75 % of the initial capacitance after 10,000 GCD cycles at a current density of 0.5A/g). Furthermore, all-solid-state asymmetric supercapacitors assembled by MnCoP/(Co,Mn)(Co,Mn)(2)O-4 nanocomposites exhibit the capacitanc...
