The specimen consisted of two materials.
Feasible materials of this part are steel or copper.
For the latter, two cases were considered – a sharp interface between the two materials and a gradually changing one.
Firstly, the interface between materials was a plane.

At present, the material performance tests at high temperatures are mainly aimed at steel materials in the construction field and new composite materials in other industries[5-8].

Up to now, there are three main electrode materials developed for supercapacitor: carbonaceous materials [1], transition mental oxides/hydroxides [2] and conducting polymers [3].
Previous reports have shown that in mixed valent manganese materials Mn(+III) forms the most reactive sites[11, 12].
And our results show that the as-prepared γ-MnOOH nanowires exhibit good electrochemical properties as electrode materials for supercapacitor.
The high capacitance, good electrochemical properties and environmentally benign of γ-MnOOH nanowires makes it attractive as electrode materials for supercapacitor.
