The ever-growing global demand of energy together with the depletion of fossil fuels makes it critical to develop sustainable and renewable energy resources. Developing relevant energy storage systems (e.g. batteries and supercapacitors) is essential to utilizing sustainable and renewable energy resources. A supercapacitor is highly beneficial in storing renewable energy. For example, when light is not shining or wind is not blowing, the energy needs to be stored in devices like batteries and supercapacitors. Among the efforts of building efficient supercapacitors, electrode materials with rational nanostructured designs have offered major improvements in performance over the past several years. This review article is intended to examine recent progress in nanostructuring supercapacitor electrode materials, highlighting the fundamental understanding of the relationship between structural properties and electrochemical performances, as well as an outlook on the next generation of nanostructured supercapacitor electrodes design. REVIEW This journal isSupercapacitors have drawn considerable attention in recent years due to their high specific power, long cycle life, and ability to bridge the power/energy gap between conventional capacitors and batteries/fuel cells. Nanostructured electrode materials have demonstrated superior electrochemical properties in producing high-performance supercapacitors. In this review article, we describe the recent progress and advances in designing nanostructured supercapacitor electrode materials based on various dimensions ranging from zero to three. We highlight the effect of nanostructures on the properties of supercapacitors including specific capacitance, rate capability and cycle stability, which may serve as a guideline for the next generation of supercapacitor electrode design.

“…Carbon microspheres have several advantages, such as regular morphology, adjustable porosity, and particle size, which could decrease the resistance of ion diffusion and result in improved electrochemical performances [14][15][16]. Moreover, the accumulation of carbon microspheres creates macroporosity that promotes the generation of ion-buffer reservoirs, which is able to minimize the diffusion distances of electrolyte ions to the interior carbon surfaces [17]. Therefore, carbon microspheres have been one of the most promising materials to be used for lithium-ion batteries [18] and supercapacitors [19].…”

“…There are two typical diffraction peaks which belong to diffraction of the (002) and (100) planes of the hexagonal graphitic carbon and the former peak have been wide. So, we can know the three samples are amorphous carbon materials with low crystallinity ,. Besides, as shown in Figure b, Raman spectra registered for the samples show two obvious peaks centered at 1350 cm −1 (correspond to the D band) and 1583 cm −1 (correspond to the G band), associated with the existence of defects or edges on disordered carbon and to ordered sp 2 bonded carbon.…”

In this work, nitrogen‐doped carbon materials with hierarchical porosity were prepared from biowaste of soybean curd residue (SCR) by KOH activation. The morphology, structure and textural properties of the carbon materials are investigated by scanning electron microscopy, transmission electron microscopy, X‐ray photoelectron spectroscopy, X‐ray diffraction, Raman spectroscopy, and N2 absorption‐desorption isotherms, respectively. The products exhibit high specific surface area of 3431 m2 g−1, high nitrogen doping level, outstanding charge storage capacity of 282 F g−1 at the current density of 0.5 A g−1 and good electrochemical stability over 10000 cycles. Moreover, it still retains 200 F g−1 (71 % of its capacitance at 0.5 A g−1) at 20 A g−1. The findings pave the way for improving charge storage capacity of supercapacitors based on activated carbon and provide a new method to transfer biowaste to effective electrode material.
