A novel electrode of NiCo2O4 nanowire arrays (NWAs) on new carbon material which takes advantage of the high electrical conductivity to boost the pseudocapacitive performance. Graphene or carbon nanotubes based thin films have been used to fabricate flexible solid-state supercapacitors with high gravimetric specific capacitances (80–200 F/g), but usually with a rather low overall or areal specific capacitance (3–50 mF/cm2) due to the ultra-small electrode thickness (typically a few micrometers) and ultralow mass loading, which is not desirable for practical applications. So we report that Edible Lentinula edodes will give more specific capacitance when compared to other carbon electrodes. NiCo2O4 mesoporous arrays together with the synergistic effect between NiCo2O4 and e-C will result in a high specific capacitance. Here we expect, with a e-C having high surface area combining with NiCo2O4 could enhance the specific capacitance, low leakage current, excellent cycling stability, and extraordinary mechanical flexibility.
Audience Take away:
• In recent years, supercapacitors, the new devices between conventional physical capacitors and batteries, also known as electrochemical capacitors, have been extensively studied to serve as one of the most promising candidates for next-generation energy storage devices due to their intriguing properties, such as high power densities, long cycling lifespans and fast charge/discharge processes, which can be proven by the number of literature works. Recently the research has been focused intensively to develop supercapacitor devices with large areal capacitance to meet the demand of miniaturization of consumer electronics, hybrid electric vehicles and micro energy systems.
• By this topic they can know well about the carbon uses for the supercapacitor. We have been researching on natural carbon materials and its properties in the application of supercapacitor. It can make the peoples to do further researches in various other natural materials.
