A composite based on multi-walled carbon nanotubes and manganese oxide with the addition of silver was obtained by liquid chemical deposition. It has been established that under this synthesis mode, a layer consisting of randomly oriented KxMnO2 nanocrystallites with a high interplanar distance (up to 6.5 Angstrem) is formed on the surface of the carbon nanotubes. It is shown that the resulting composite can be promising as an active component for increasing the capacitance and rate characteristics of commercial grades of carbon black when used in supercapacitors. Keywords: supercapacitor, specific capacitances, redox reactions, rate capability.
