中文摘要	nanostructured manganese oxides with different crystallization behaviors were fabricated by a simple redox reaction between kmno4 and nano2 aqueous solution. mno2 nanostructures with sphere-, rod-, wire-, plate-and flower-like morphologies were crystallized, and the relationship between crystallization characteristics and their electrochemical performances were studied. the electrochemical energy storage behaviors of these samples were investigated by cyclic voltammetry and galvanostatic charge-discharge measurements processed using noncorrosive na2so4 as the electrolyte. a maximum specific capacitance 200 f g(-1) was obtained for poorly crystallized alpha-mno2 at a current density of 1 a g(-1). for different crystallographic mno2 phases, their specific capacitance values increase in the order: beta < gamma < delta < alpha, meanwhile, for any particular mno2 phase, their electrochemical energy storage performances decrease with increasing crystalline nature and particle size.
