Mechanical and electrochemical performance of hybrid laminated structural composites with carbon fiber/ solid electrolyte supercapacitor interleaves

Designing Structural Electrochemical Energy Storage Systems: A Perspective on the Role of Device Chemistry

“…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.…”

Materials systems for interleave toughening in polymer composites

“…Sun et al [141] investigated the combination of Kevlar/epoxy prepreg laminates with a carbon fibre/solid-electrolyte interleaf as a supercapacitor, concluding that the interleaf could provide superior electrochemical performance. They also suggested that further research should explore the use of CNTbased continuous fibres as electrodes, utilising their high specific surface area.…”

3D porous cementitious electrolytes with “stream-reservoir” ionic channels for high multifunctional performance structural supercapacitors

“…[1][2][3][4][5] Compared with structural batteries, structural supercapacitors (SSCs) have become a research hotspot for engineered energy-storage devices due to their long cycle life, fast charging and discharging speeds and high power density. [6][7][8][9][10] Typically, the combination of electrodes and solid-state electrolytes is used to fabricate SSCs. 11 In addition to electrode materials, the solid-state electrolyte is the key part that determines the electrochemical performance of SSCs.…”
