Anchoring sea-urchin-like Co(OH)2 microspheres on nickel foam as three-dimensional free-standing electrode for high-performance supercapacitors

Abstract Transition metal hydroxides have emerged as promising materials in supercapacitor. In this work, a free-standing supercapacitor electrode was prepared. Sea-urchin-like Co(OH)2 microspheres were hydrothermally deposited on a Ni foam substrate, showing a hierarchical 3D free-standing structur...

520			\|a Abstract Transition metal hydroxides have emerged as promising materials in supercapacitor. In this work, a free-standing supercapacitor electrode was prepared. Sea-urchin-like Co(OH)2 microspheres were hydrothermally deposited on a Ni foam substrate, showing a hierarchical 3D free-standing structure. The 3D framework endows the as-prepared electrode with improved supercapacitive performances. The influence of the hydrothermal time on the structure and electrochemical performances of the resulting products are investigated systematically. It delivers a capacitance of 1916 F/g (15.9 F/$ cm^{2} $) and 699 F/g (5.8 F/$ cm^{2} $) at 10 mA/$ cm^{2} $ and 100 mA/$ cm^{2} $, respectively, exhibiting excellent rate performance. The capacitance retains about 79.3% after 5000 charging-discharging cycles at 80 mA/$ cm^{2} $. Various ill-defined rod-like and stacked plate-like CoOOH materials are obtained from the electrodes after the cycles, which is responsible for the property deterioration of Co(OH)2/Ni foam.

In this work, a free-standing supercapacitor electrode was prepared. Sea-urchin-like Co(OH)2 microspheres were hydrothermally deposited on a Ni foam substrate, showing a hierarchical 3D free-standing structure. The 3D framework endows the as-prepared electrode with improved supercapacitive performances. The influence of the hydrothermal time on the structure and electrochemical performances of the resulting products are investigated systematically. It delivers a capacitance of 1916 F/g (15.9 F/$ cm^{2} $) and 699 F/g (5.8 F/$ cm^{2} $) at 10 mA/$ cm^{2} $ and 100 mA/$ cm^{2} $, respectively, exhibiting excellent rate performance. The capacitance retains about 79.3% after 5000 charging-discharging cycles at 80 mA/$ cm^{2} $. Various ill-defined rod-like and stacked plate-like CoOOH materials are obtained from the electrodes after the cycles, which is responsible for the property deterioration of Co(OH)2/Ni foam.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Supercapacitor</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hydrothermal synthesis</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Sea-urchin-like</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Area specific capacitance</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Capacitance retention</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhu, Sha</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Gao, Xiang</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jiang, Xiaoping</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Yuhua</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Meng, Fanhui</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Ionics</subfield><subfield code="d">Berlin : Springer, 1995</subfield><subfield code="g">27(2021), 2 vom: 02.

abstract	Abstract Transition metal hydroxides have emerged as promising materials in supercapacitor. In this work, a free-standing supercapacitor electrode was prepared. Sea-urchin-like Co(OH)2 microspheres were hydrothermally deposited on a Ni foam substrate, showing a hierarchical 3D free-standing structure. The 3D framework endows the as-prepared electrode with improved supercapacitive performances. The influence of the hydrothermal time on the structure and electrochemical performances of the resulting products are investigated systematically. It delivers a capacitance of 1916 F/g (15.9 F/$ cm^{2} $) and 699 F/g (5.8 F/$ cm^{2} $) at 10 mA/$ cm^{2} $ and 100 mA/$ cm^{2} $, respectively, exhibiting excellent rate performance. The capacitance retains about 79.3% after 5000 charging-discharging cycles at 80 mA/$ cm^{2} $. Various ill-defined rod-like and stacked plate-like CoOOH materials are obtained from the electrodes after the cycles, which is responsible for the property deterioration of Co(OH)2/Ni foam.
