Supercapacitors are intermediate devices between conventional batteries and dielectric capacitors that can be used in various electric systems.The pseudo-capacitors have drawn great attentions because of their ability to embrace the advantages of both lithium ion batteries(high energy density)and capacitors(high power density).[1] Among various supercapacitor electrode materials,the manganese oxide is one of the most promising candidates due to its high specific capacitance,environmental compatibility and cost effectiveness.Nevertheless,they still suffer from some drawbacks,such as low specific surface area and poor conductivity.Hollow micro-/nano-structured materials can overcome the above drawbacks due to their large specific surface area,short transport length and good structural stability.[2]
