Abstract

Copper oxide is established as an important compound in technology due to its semi-conducting nature and high chemical stability as well as economic benefits. These features have made it a good candidate in energy storage applications. Further, extensive attention has been paid to advancement of supercapacitors- a complementary device between battery and conventional capacitors – due to their unique features such as high power, long cycle life, and environmentally friendly nature. In addition, copper oxide has sparked interest in preparation of applicable positive electrodes which can be used in preparation of supercapacitors. Meanwhile, copper oxide is mixed with polarized liquids and polymers easily, and it is has relative stable chemical and physical properties. Electrochemical features of copper oxide depend on the morphology where proper architectural design of electrode materials can be optimized in these devices. In this review, copper oxide synthesis and its redox mechanism as cathode materials will be explored as well as the application of various copper oxide compounds in preparation of high-performance supercapacitors.
