A brief review on stretchable, compressible, and deformable supercapacitor for smart devices

Polyimide/Ionic Crystal-Based Hybrid Electrolyte for a Self-Powered Multistage Fire Alarm

“…Supercapacitors are satisfactory candidates for power supplies due to their unique properties, such as stable and high power output, rapid charge and discharge ability, low cost, and easy-to-industrialize. − However, the application of supercapacitors is inhibited by the low boiling point of liquid electrolytes and flammable polymer-based separators (such as polyethylene, polyoxyethylene, polyacrylonitrile). − These polymer-based separators usually shrank at a temperature higher than 80 °C, failing supercapacitors at extreme temperatures. Thus, the thermally stable electrolyte for supercapacitors is urgently desirable.…”

Construction of shrimp shell (SS) waste-based carbon electrode-gel polymer electrolyte (GPE) system for flexible symmetric supercapacitors

“…Supercapacitor systems consist of electrodes and electrolytes, which can be divided into liquid (aqueous and organic liquids) and solid-state (all-solid and gel) supercapacitors according to the type of electrolyte. 3 Safety issues such as electrolyte leakage may occur in supercapacitors using liquid as the electrolyte. In the past ten years, the optimization of electrode and electrolyte performance has rapidly advanced.…”

Recent progress in the development of smart supercapacitors

“…Therefore, it is very important to summarize related works on intelligent supercapacitors. Although researchers have conducted considerable research works on smart supercapacitors, there is still little literature summary on the related works of different smart supercapacitors 51–53 …”

“…Although researchers have conducted considerable research works on smart supercapacitors, there is still little literature summary on the related works of different smart supercapacitors. [51][52][53] This review comprehensively summarizes, deeply discusses, and prospects the relevant progress, existing problems, and future development trends of research works on smart supercapacitors in recent years, such as electrochromism, self-healing, shape memory, self-charging, electromagnetic shielding, and sensing (Figure 1). The purpose of this review is to provide a convenient and fast reference for researchers in related fields to promote the rapid and healthy development of the whole field and the intelligence era.…”
