Binder-Free Porous 3D-ZnO Hexagonal-Cubes for Electrochemical Energy Storage Applications

Abstract: Considerable efforts are underway to rationally design and synthesize novel electrode materials for high-performance supercapacitors (SCs). However, the creation of suitable materials with high capacitance remains a big challenge for energy storage devices. Herein, unique three-dimensional (3D) ZnO hexagonal cubes on carbon cloth (ZnO@CC) were synthesized by invoking a facile and economical hydrothermal method. The mesoporous ZnO@CC electrode, by virtue of its high surface area, offers rich electroactive sites… Show more

“…Namely, by combining metal oxide and carbon counterparts in the nanocomposite, it is possible to enhance the charge storage capacity and thus create a promising supercapacitor electrode material. This approach allows overcoming the drawbacks of both materials and increases the efficiency of charge storage due to the synergistic effects. , In a nanocomposite structure, a carbon-based counterpart accumulates charge through the formation of an electric double layer between the electrode surface and the electrolyte, whereas metal oxides, such as ZnO, RuO 2 , SnO 2 , TiO 2 , MnO 2 , and Fe 3 O 4 , are known to exhibit pseudocapacitance through fast reversible Faraday redox reactions. Carbon-based structures are characterized by such properties as high conductivity, chemical stability, and mechanical strength.…”
