Preparation of a multifunctional organogel and its electrochemical properties

Abstract

A facile methodology to fabricate high elastic organogel for supercapacitors is demonstrated. Stable polymer organogel was obtained in DMSO by simply esterification reaction. This organogel showed high mechanical performance, flexibility，high...

Wide-Temperature-Range Flexible Supercapacitors Using a Multipurpose Organogel Electrolyte

“…PVA/4SD organogel electrolytes also demonstrate weak redox peaks because the formation of ester bonds between PVA and 4SD and acid catalysis cause ester bond hydrolysis, which belongs to a redox process. 54 By comparison (Figure 4D), it can be found that the organogel electrolyte with KI has very high ionic conductivity, up to 30.12 mS cm −1 , on account of KI can increase the ion concentration and act as a plasticizer to promote the movement of ions in the electrolyte. 55 Nyquist plots for PVA, PVA/4SD, and PVA/ power supplies and successfully lit a small 3 V calculator (Figure 4L).…”

“…The CV curves of PVA, PVA/4SD, and PVA/4SD/KI organogel-based SCs are compared at a scanning rate of 25 mV s –1 (Figure C). PVA/4SD organogel electrolytes also demonstrate weak redox peaks because the formation of ester bonds between PVA and 4SD and acid catalysis cause ester bond hydrolysis, which belongs to a redox process . By comparison (Figure D), it can be found that the organogel electrolyte with KI has very high ionic conductivity, up to 30.12 mS cm –1 , on account of KI can increase the ion concentration and act as a plasticizer to promote the movement of ions in the electrolyte .…”

Multifunctional Antifreezing Organogel Polyelectrolyte for a Flexible Supercapacitor

“…With the continuous progress and development of wearable electronic technology, flexible electronic products with the characteristics of portability, wearability, collapsibility, miniature, and lightweight have been paid more and more attention. − As we know, in lots of energy storing devices, flexible solid-state supercapacitors have become one of the most hopeful flexible energy storage devices due to their large specific capacitance, rapid charging and discharging properties, wonderful stability, and excellent mechanical properties. − The rational design of electrode or electrolyte materials − and the optimization of device configuration have become the direction of development to build high-performance flexible supercapacitors (FSCs). Conductive gels with intrinsic flexibility, significant mechanical recycling, and remarkable ionic conductivity can not only be used as ideal materials for FSC electrolytes − but also have considerable applications in tissue engineering, drug delivery, water treatment, bioengineering, and many other fields.…”

Effect of polyacrylamide morphology templated using lyotropic liquid crystal on the proton conductivity of acid hydrogels

“…Hydrogels, comprising three-dimensional polymeric networks and aqueous mediums, have been regarded as promising electrolytes owing to their dimensional stability and chemical activity. [1][2][3] A few proton-conductive hydrogels have been developed by adding inorganic acids or incorporating acid moieties into polymeric networks. [4][5][6] Regulating acid concentration is regarded as an effective way to tune the conductivity of hydrogels.…”
