Self-assembled synthesis of hierarchical nanostructured CuO with various morphologies and their application as anodes for lithium ion batteries

Morphology and phase tuning of α- and β-MnO2nanocacti evolved at varying modes of acid count for their well-coordinated energy storage and visible-light-driven photocatalytic behaviour

“…The rst is the capacity loss from the formation of solid electrolyte interface (SEI) layer which is a gel-like layer, containing ethylene oxide-based oligomers, LiF, Li 2 CO 3 , and lithium alkyl carbonate (ROCO 2 Li), during rst discharging process. 62 The incomplete decomposition of SEI lm hinders intercalation and deintercalation of Li + ions on to electrode surface. This is common in all 3d transition metal oxides including CuO, NiO and 63 Secondly, repeated charging-discharging processes cause large volume expansion/contraction resulting in electrode pulverization.…”

Synthesising Metal Oxide Materials and Their Composite Nanostructures for Sensing and Optoelectronic Device Applications

“…CuO NSs have shown many attractive properties such as; they can easily be grown on various substrates, prepared as different morphologies, low cost, and they are non-toxic. The researchers have been interested in the synthesis of various morphologies of CuO because the size and morphology of the CuO have a large effect on the electrochemical and catalytic nanodevices performance [51]. Several morphologies of CuO have been grown by the hydrothermal methods such as NRs [52], nanosheets [53], nanoflowers [54] and nanotubes [55].…”

Effect of precipitating agent NaOH on the preparation of copper oxide nanostructures for electrochemical applications

“…Of these, CuO has attracted much research interest due to its unique properties, such as high catalytic activity, easy synthesis route, environmentally friendly nature and variable morphologies at the nanoscale. It has found potential applications in electrochemistry as an electrode material for lithium-ion batteries and electrochemical capacitors, solar energy systems, heterogeneous catalysts and selective gas sensors [13,14]. CuO is a metal oxide with encouraging redox properties, and thus thin CuO films fabricated by different techniques such as electrodeposition [15] and chemical bath deposition [16] can find certain use in supercapacitors.…”
