Manganese oxides are considered to be a promising material for pseudocapacitors because of their high theoretical specific capacitance,low cost,and environmentally friendliness.The practical capacitive behavior of MnO2 materials is,however,far from the theoretical value due to their poor electrical conductivity(approximately 10-5 to 10-6 S cm-1) and mechanical instability.

钠离子电池具有资源丰富、价格低廉等优点,被认为是大规模储能的理想选择之一,得到了研究者们越来越多的关注[1].目前的研究难点之一,主要集中于缺乏高容量、高电压的正极材料.可能原因主要有两点:其一,钠离子的离子半径较大(0.102 nm),在传统的氧化物晶格中脱嵌动力学较慢,导致容量利用率较低;其二,Na+/Na电对的还原电势(-2.71 V vs.SHE)较Li+/Li电对(-3.02V vs.S
