“…Since the energy storage mechanism of carbon-based materials relies mainly on the electrostatic adsorption and desorption of electrolyte ions onto the electrode surface, carbon-based materials are expected to cycle stably over a wide temperature range. 15,147,148 Currently, the working temperature of activated carbon, onionlike carbon, and RGO increased to −70°C to 100°C, −50°C to 80°C, and −40°C to 200°C, respectively. 64 Composition adjustment and structural design are efficient strategies to speed up the diffusion and adsorption of ions to retain good electrochemical performance with a wide temperature range.…”

Solid‐state supercapacitors (SSCs) are emerging as one of the promising energy storage devices due to their high safety, superior power density, and excellent cycling life. However, performance degradation and safety issues under extreme conditions are the main challenges for the practical application. With the expansion of human activities, such as space missions, polar exploration, and so on, the investigation of SSC with wide temperature tolerance, high energy density, power density, and sustainability is highly desired. In this review, the effects of temperature on SSC are systematically illustrated and clarified, including the properties of the electrolyte, ion diffusion, and reaction dynamics of the supercapacitor. Subsequently, we summarize the recent advances in wide‐temperature‐range SSCs from the aspect of electrolyte modification, electrode design, and interface adjustment between electrode and electrolyte, especially with critical concerns on ionic conductivity and cycling stability. In the end, a perspective is presented, expecting to promote the practical application of the SSC in harsh conditions.

“…Another one is based on the use of materials that can store electrical energy on their internal surface through the use of electrostatic forces, known as electrochemical double-layer capacitors (EDLC) [ 6 , 16 ]. Typically, this type of SC uses carbon-based materials [ 17 ] such as microporous or mesoporous carbons [ 18 , 19 , 20 ], graphene [ 21 , 22 , 23 ], or carbon nanotubes [ 22 , 24 , 25 ] as the active material.…”

The use of fossil fuels has contributed significantly to environmental pollution and climate change. For this reason, the development of alternative energy storage devices is key to solving some of these problems. The development of lightweight structures can significantly reduce the devices’ weight, thereby reducing energy consumption and emissions. Combining lightweight structures with alternative energy storage technologies can further improve efficiency and performance, leading to a cleaner and more sustainable system. In this work, for the first time, MOF-74 materials with different divalent metal ions have been synthesized directly on carbon fiber, one of the most widely used materials for the preparation of electrodes for supercapacitors with structural properties. Different techniques, such as nitrogen adsorption–desorption isotherms, cyclic voltammetry or galvanostatic charge–discharge, among others, were used to evaluate the influence of the metal cation on the electrochemical capacitance behavior of the modified electrodes. The Co-MOF-74 material was selected as the best modification of the carbon fibers for their use as electrodes for the fabrication of structural supercapacitors. The good electrochemical performance shown after the incorporation of MOF materials on carbon fibers provides a viable method for the development of carbon fiber electrodes, opening a great variety of alternatives.
