This excellent performance is discussed in terms of the manganese dioxide electrodeposition mechanism, in particular the growth mechanism under the preferred slow mass transport of electro-active species, and its effects on morphology. Furthermore, the origin of the enhanced capacitance is discussed, in which case we have proposed arises from contributions made by hydroxyl groups on the manganese dioxide nano-particulate surface, in addition to the fast redox reactions that are necessary for pseudo-capacitance.]]> Sat 24 Mar 2018 08:10:12 AEDT ]]>
