Manganese oxide micro-supercapacitors with ultra-high areal capacitance

Author affiliations

Abstract

A symmetric micro-supercapacitor is constructed by electrochemically depositing manganese oxide onto micro-patterned current collectors. High surface-to-volume ratio of manganese oxide and short diffusion distance between electrodes give an ultra-high areal capacitance of 56.3 mF cm−2 at a current density of 27.2 μA cm−2.
