- Manganese-amine complexes were thermaly decomposed at 260 °C.
- Multi-plate thin films of manganese oxide were synthesized.
- Thin films consisted of Plates 200Â nm in thickness with nanoparticles.
- Specific capacitances of multi-plate, thin-films reached 938Â F/g.
Multi-plate, thin-film manganese oxide electrodes were synthesized via the thermal decomposition of a complex of manganese (II) formate (MnF) and triethylenetetramine (TETA) at 260 °C. These approximately 200 nm thick plates contained 50-100 nm nanoparticles and were obtained from a complex of TETA and MnF with a molar ratio of 4. A cyclic voltammetry (CV) test confirmed the pseudocapacitive properties of these multi-plate, thin-film manganese oxide electrodes. The specific capacitance of multi-plate, thin-film electrodes with a mass loading of 10 μg was calculated from a CV curve at 10 mV/s that reached 938 F/g. The specific capacitance degradation was measured via a galvanostatic charge-discharge of 0.5 mA/cm2 and was almost stable after 1,000 cycles, which resulted in good cycle stability. Thus, an electrode of non-composite manganese oxide with high specific capacitance and good stability was obtained via a simple one-step fabrication process by thermal decomposition.
