“…Traditionally, conductive carbons, conducting polymers, metal organic frameworks and various metal oxides have been used to improve the conductivities of some conversion cathodes and reduce their dissolution during cycling ( Guo and Fu, 2018 ). Conversion-type cathodes may be attractive in SESDs as CFs and CF-supported aerogels ( Qian et al, 2013b ; Nguyen et al, 2019 ) could potentially solve the low conductivity and voltage hysteresis issues. To date, there has only been one approach towards structural Li-S batteries ( Huang et al, 2020 ); yet its electrolyte-to-sulfur weight ratio (∼27) was extremely high for practical applications given that an excess of electrolyte (ratio >4) has an adverse impact on the energy density of the battery at the system level.…”

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.

“…While this combination of CNTs and PVDF ionogels have been explored for the fabrication of SSCs previously, few electrolyte configurations have been explored for optimisation of both electrochemical and mechanical performance in composites aside from [ 12 ]. Previous SSC configurations have examined sandwiching a self-contained supercapacitor stack with ionogel electrolyte into a composite [ 12 , 47 ] or infusing the whole SSC and composite structure with an electrolyte/resin mixture as the matrix material [ 5 , 11 , 23 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 ]. Embedding a self-contained supercapacitor is structurally disruptive and produces localised increases in laminate thickness and stress concentrations.…”

Composite Structural Supercapacitors: High-Performance Carbon Nanotube Supercapacitors through Ionic Liquid Localisation

Composite structural supercapacitors (SSC) are an attractive technology for aerospace vehicles; however, maintaining strength whilst adding energy storage to composite structures has been difficult. Here, SSCs were manufactured using aerospace-grade composite materials and CNT mat electrodes. A new design methodology was explored where the supercapacitor electrolyte was localised within the composite structure, achieving good electrochemical performance within the active region, whilst maintaining excellent mechanical performance elsewhere. The morphologies of these localised SSC designs were characterised with synchrotron X-ray fluorescence microscopy and synchrotron X-ray micro-computed tomography and could be directly correlated with both electrochemical and mechanical performance. One configuration used an ionogel with an ionic liquid (IL) electrolyte, which assisted localisation and achieved 2640 mW h kg−1 at 8.37 W kg−1 with a corresponding short beam shear (SBS) strength of 71.5 MPa in the active area. A separate configuration with only IL electrolyte achieved 758 mW h kg−1 at 7.87 W kg−1 with SBS strength of 106 MPa in the active area. Both configurations provide a combined energy and strength superior to results previously reported in the literature for composite SSCs.
