[12,[42][43][44][45][46][47] The EIS results (Figure 7) offer insights into the contributions to the electrical resistance of the fabricated supercapacitors. Moreover, we directly measured the electrical resistance properties of the electrodes for supercapacitors (Table 4).…”

High‐performance supercapacitors based on activated carbons (AC) derived from polyethylene (PE), which is one of the most abundant plastic materials worldwide, are fabricated. First, PE carbons (PEC) are prepared via sulfonation, which is a reported solution for successful carbonization of innately non‐carbonizable PE. Then, the physico‐electrical changes of PECs upon a chemical activation process are explored. Interestingly, upon the chemical activation, PECs are converted ACs with a large surface area and high crystallinity at the same time. Subsequently, PE‐derived ACs (PEAC) are exploited as electrode materials for supercapacitors. Resultant supercapacitors based on PEACs exhibit impressive performance. When compared to supercapacitors based on YP50f, representative commercial ACs, devices using PEACs presented considerably good capacitance, low resistance, and great rate capability. Specifically, the retention rate of devices using PEACs is significantly higher than that of YP50f‐based devices. At the high rate of charge−discharge situation reaching 7 A g−1, the capacitance of supercapacitors using PEACs is ≈70% higher than that of YP50f‐based devices. It is assumed that the carbon structure accompanying both large surface area and high conductivity endows a great electrochemical performance at the high current operating conditions. Therefore, it is envisioned that PE may be a viable candidate electrode material for commercially available supercapacitors.

“…Figure 4c presents the Nyquist plots of the activated carbon and HPC electrode samples within the frequency range of 200 kHz to 100 MHz. In the high-frequency region, the real axis intercept represents the internal resistance, which includes the sum of the contact resistance between the active material and current collector, the intrinsic resistance of the active material, and the ionic resistance of the electrolyte; the semicircle in the middle frequency region corresponds to the charge transfer resistance [33,34]. In the Nyquist plots, all the electrodes of the samples presented a negligible semicircle, indicating a low charge transfer resistance.…”

Carbon materials have gained considerable attention in recent years due to their superior properties. Activated carbon has been used in supercapacitors due to its density and rapid adsorption capability. The sp2–sp3 hybrid porous carbon materials are synthesized using herringbone-type carbon nanofibers (CNFs) and carbonized spherical phenol resins, with KOH as the activating agent. The morphology of the hybrid porous carbon facilitates the formation of ribbon-like nanosheets from highly activated CNFs wrapped around spherical resin-based activated carbon. The etching and separation of the CNFs produce a thin ribbon-like nanosheet structure; these CNFs simultaneously form new bonds with activated carbon, forming the sp2–sp3 hybrid porous structure. The relatively poor electrical conductivity of amorphous carbon is improved by the 3D conductive network that interconnects the CNF and amorphous carbon without requiring additional conductive material. The composite electrode has high electron conductivity and a large surface area with a specific capacitance of 120 F g−1. Thus, the strategy substantially simplifies the hybrid materials of sp2-hybridized CNFs and sp3-hybridized amorphous spherical carbon and significantly improves the comprehensive electrochemical performance of supercapacitors. The developed synthesis strategy provides important insights into the design and fabrication of carbon nanostructures that can be potentially applied as electrode materials for supercapacitors.

“…CFs may be electrochemically active themselves, or act as framework and current collector for a multifunctional matrix packed around them. EDLCs are particularly attractive, since the energy storage process is entirely physical, depending only on the interface between electrode and electrolyte ( Figures 2A,B ) ( Li et al, 2010 ; Qian et al, 2013a ; Shirshova et al, 2013a ; Qian et al, 2013b ; Javaid et al, 2014 ; Shirshova et al, 2014 ; Westover et al, 2014 ; Greenhalgh et al, 2015 ; Javaid et al, 2016 ; Senokos et al, 2016 ; Kwon et al, 2017 ; Senokos et al, 2017 ; Shen and Zhou, 2017 ; Xu and Zhang, 2017 ; Li et al, 2018a ; Chen et al, 2018 ; Javaid et al, 2018 ; Javaid and Irfan, 2018 ; Muralidharan et al, 2018 ; Senokos et al, 2018 ; Aderyani et al, 2019 ; Flouda et al, 2019a ; Chen et al, 2019 ; Patel et al, 2019 ; Reece et al, 2019 ; Patel et al, 2020b ; Rana et al, 2020 ; Reece et al, 2020 ; Sun et al, 2020 ; Sánchez-Romate et al, 2021 ; Subhani et al, 2021 ; Xu et al, 2021 ). The central advantage for SESDs, is that there is little or no change in volume, and no (re)dissolution of material, associated with the electrochemical process, minimizing stresses, and simplifying the structural design, whilst ensuring an excellent cycle life.…”

Structural energy storage devices (SESDs), designed to simultaneously store electrical energy and withstand mechanical loads, offer great potential to reduce the overall system weight in applications such as automotive, aircraft, spacecraft, marine and sports equipment. The greatest improvements will come from systems that implement true multifunctional materials as fully as possible. The realization of electrochemical SESDs therefore requires the identification and development of suitable multifunctional structural electrodes, separators, and electrolytes. Different strategies are available depending on the class of electrochemical energy storage device and the specific chemistries selected. Here, we review existing attempts to build SESDs around carbon fiber (CF) composite electrodes, including the use of both organic and inorganic compounds to increase electrochemical performance. We consider some of the key challenges and discuss the implications for the selection of device chemistries.
