As a major agro waste of coconut, coconut husk is presented here as cheap, abundant, novel, and sustainable green source high-surface-area activated carbon for high-performance supercapacitor electrodes. The present communication satisfies one the United Nations Sustainable Development Goals (UN goals) an affordable, reliable, solution existing energy technologies. carbonization activation via one-step integrated microwave pyrolysis system vacuum furnace, respectively, are production technologies used conversion biomass into carbon. chemical impregnation was performed in two different agents (KOH H3PO4) three higher temperatures (700, 800, 900 °C), their physical properties supercapacitive performances were analyzed compared. A high surface area 1218 m2 g–1 achieved KOH (ACKOH 900) with weight ratio AC to 1:2 at temperature °C, yielding excellent specific capacitance 342 F g–1, much than that H3PO4 (243 g–1). storage performance further carried out by fabricating symmetric device aqueous polymer gel (PVA-H3PO4) electrolyte media, cyclic stability nearly 100% power density both KOH- H3PO4-activated samples temperature, which can be interconnected its enhanced porosity facilitates fast ion transport improves performance. fabricated cells, when red LEDs, showed complete discharge end 15 min while maximum glow 30 single LED, took 1 h discharge. Furthermore, investigation, coconut-husk-derived shows promise capacitance, low cost, renewable material, consequently suggesting promising avenue toward high-power, renewable, clean devices.

Recent progress in biocompatible miniature supercapacitors

Energy Materials, Год журнала: 2025, Номер 5(7)

Опубликована: Март 10, 2025

With the advancement of wearable and implantable health medical electronics, biocompatible miniature energy storage devices were developed rapidly. In particular, supercapacitors (BMSCs) have advantages conventional supercapacitors, such as high-power density, fast charging/discharging rate, long operating lifetime, well strong selectivity materials. They are expected to play an important role in personalized electronic integration systems. Biocompatibility involves biosafety materials relates mechanics geometrical forms. For example, BMSCs should be thin compact, ensuring ease portability comfort for users. also flexible stretchable conform skin or tissue, providing stable power electronics even under deformation. Furthermore, biodegradability/ bioabsorbability ensures they both body- environment-friendly. This review summarizes recent research progress devices, including basic requirements selection components. Additionally, advanced applications multifunctional systems real-time monitoring treatment introduced, along with associated challenges prospects.
