Advanced Energy Materials, Journal Year: 2023, Volume and Issue: 13(29)

Published: June 16, 2023

Abstract High‐performance electrochemical applications have expedited the research in high‐power devices. As such, supercapacitors, including electrical double‐layer capacitors (EDLCs) and pseudocapacitors, gained significant attention due to their high power density, long cycle life, fast charging capabilities. Yet, no device lasts forever. It is essential understand mechanisms behind performance degradation aging so that these bottlenecks can be addressed tailored solutions developed. Herein, factors contributing of electrode materials, electrolytes, other aspects system, such as pore blocking, compositions, functional groups, corrosion current collectors are examined. The monitoring characterizing methods, situ, ex situ techniques explored. In addition, different types electrolytes materials effects from an industrial application standpoint analyzed. Next, how degradations electrolyte decompositions lead failure, composition, affect device's lifespan Finally, future directions challenges for reducing supercapacitors' degradation, developing new methods devices summarized.

Boron and fluorine Co-doped laser-induced graphene towards high-performance micro-supercapacitors

Carbon, Journal Year: 2023, Volume and Issue: 212, P. 118101 - 118101

Published: May 11, 2023

Laser-induced graphene (LIG) has attracted extensive research as an electrode material for micro-supercapacitors (MSC). However, the low capacitive performance of LIG arising from both limited specific surface area and few active sites remains challenging. Herein, in situ doping fluorine boron atoms into laser-induced was innovatively achieved via laser direct writing approach using boron-doped fluorinated polyimide (FB-PI) precursor. The porous co-doped (FB-LIG) exhibits more improved wettability significantly enhanced due to synergistic effect co-doping. By tuning weight ratio fluorine, MSC utilizing FB-LIG poly(vinyl alcohol) (PVA)/H2SO4 gel electrolyte delivers a high areal capacitance 49.81 mF/cm2 at current density 0.09 mA/cm2, 23 times higher that commercial (PI)-based LIG, 3 PI-based LIG. In addition, MSCs possess excellent mechanical stability flexibility, rendering them promising flexible wearable microelectronics.
