Finally, the device showed the energy density of 32.3 Wh kg −1 at a power density of 504.8 W kg −1 with 83.5% capacitance retention after 1000 cycles. Roy et al [102] established an asymmetric supercapacitor device with high energy density of 85.7 Wh kg −1 at a power density of 11.2 kW kg −1 by employing the NiO-CNT as a positive and AC as a negative electrode, respectively. Shanmugavani and Selvan [103] constructed an asymmetric supercapacitor using AC as a negative electrode and CuCo 2 O 4 /CuO nanocomposites as a positive electrode, and it showed an energy density of 18 Wh kg −1 at a power density of 259 W kg −1 with 100% of capacitance retention after 5000 cycles.…”

With improvement of global economy, the fatigue of energy becomes inevitable in twenty-first century. It is expected that the increase of world energy requirements will be triple at the end of this century. Thus, there is an imperative need for development of renewable energy sources and storage systems. Among various energy storage systems, supercapacitors are ascertained one of the most significant storage devices. But the development of supercapacitor devices with high power and energy density are the greatest challenges for modern research. In this article, transition metal oxides such as TiO 2-V 2 O 5 , NiMn 2 O 4 etc. with porous structure are considered as high performance supercapacitors electrode. The effects of its structural, morphological and electrochemical properties have been studied extensively. A TiO 2-V 2 O 5 and NiMn 2 O 4 based electrode delivered specific capacitance of 310 and 875 F g À1 , respectively at a scan rate 2 mV s À1. This TiO 2-V 2 O 5 based asymmetric supercapacitor also exhibits excellent device performance with specific energy 20.18 W h kg À1 at specific power 5.94 kW kg À1 , and retained 88.0% specific capacitance at current density of 10 A g À1 after 5000 cycles.
