Abstract
- • A novel leaf-like Co 3 O 4 composites were prepared by magnetic-field-assisted chemical deposition method for supercapacitor electrode. • The effect of the magnetic field on the morphology of leaf-like microstructure was studied. • The optimal Co 3 O 4 at 80 mT has the highest capacitance of 1295 Fg−1 at 1 A/g and good retention (94.1 % over 10,000 cycles). A novel leaf-like cobalt oxide particles were prepared by a magnetic field assisted chemical deposition method and subsequently sintering process. The phase structure, morphological changes, and electrochemical performance of the cobalt oxide particles were systematically tested and the effect of the magnetic field on the product morphology was studied. Owin to the unique leaf-like shape structure, the optimal Co 3 O 4 particles at 80 mT displayed the highest specific capacitance of 1247.4 Fg−1 at 1 A/g, with a retention rate of 94.1 % after 10,000 cycles.
