Asymmetric supercapacitors with high energy density based on helical hierarchical porous Na(x)MnO(2) and MoO(2)
Helical hierarchical porous Na(x)MnO(2)/CC and MoO(2)/CC, which are assembled from nanosheets and nanoparticles, respectively, are fabricated using a simple electrodeposition method. These unique helical porous structures enable electrodes to have a high capacitance and an outstanding cycling perfor...

description | Helical hierarchical porous Na(x)MnO(2)/CC and MoO(2)/CC, which are assembled from nanosheets and nanoparticles, respectively, are fabricated using a simple electrodeposition method. These unique helical porous structures enable electrodes to have a high capacitance and an outstanding cycling performance. Based on the helical Na(x)MnO(2)/CC as the positive electrodes and helical MoO(2)/CC as the negative electrodes, high performance Na(x)MnO(2)/CC//MoO(2)/CC asymmetric supercapacitors (ASCs) are successfully assembled, and they achieve a maximum volume C (sp) of 2.04 F cm(–3) and a maximum energy density of 0.92 mW h cm(–3) for the whole device and an excellent cycling stability with 97.22% C (sp) retention after 6000 cycles. |
