Wide Temperature All‐Solid‐State Ti3C2Tx Quantum Dots/L‐Ti3C2Tx Fiber Supercapacitor with High Capacitance and Excellent Flexibility

“…In order to assemble all solid-state flexible supercapacitors, flexible electrolyte has an important impact on the quality, volume, flexibility, and electrochemical window of the assembled devices. [47] Although hydrogel electrolytes (HGE) have the advan-tages such as low cost, high deformability, high ionic conductivity similar to aqueous electrolytes, and flexibility of solid polymer electrolytes, [48] the performance of the assembled HGE flexible supercapacitors (HGE FSC) is very vulnerable to changes in the surrounding environment due to the freezing and evaporating of water in the hydrogel electrolytes. [49] Especially when the environment temperature is below 0 °C, the device performance for the assembled HGE FSC will significantly reduce due to the obvious reduction of the ionic conductivity, flexibility, and the close contact between electrolyte and electrode.…”

Impact of hydrogen bonding interaction energy on the polymerization kinetics of polymerizable deep eutectic solvent monomers

“…Currently, the conductor materials for flexible electronic devices are mainly composed of conductive polymers, 10,11 metal-based conductive materials, 12 hydrogels, [13][14][15] and ionic gels. [16][17][18] However, conductive polymers are generally complex and costly to prepare. A higher modulus of elasticity of metal-based conductive materials will lead to stress concentration and fracture during bending or stretching, affecting the stability and reliability of the device.…”

Advancements in silicon carbide-based supercapacitors: materials, performance, and emerging applications

“…One promising application of supercapacitors lies within the electric vehicle sector, where they can complement traditional batteries. 5–8 By doing so, they improve vehicle acceleration performance, enhance range, optimize energy efficiency, and reduce fuel consumption. 9–11 In renewable energy, particularly solar and wind power generation, supercapacitors can effectively store surplus energy and balance supply-demand fluctuations.…”
