Summary: In this study, three-dimensional activated graphitic carbon spheres (AGCS) were synthesized by activating and graphitizing Fe-tannic acid coordination spheres with the help of KOH. The AGCS with nanosheets-assembled complex intersecting channel system can expose more active sites, which is beneficial for charge storage. Simultaneous activation-graphitization can also solve the trade-off relationship between porosity and conductivity of carbon materials. The optimized AGCS-2, with a large specific surface area, abundant ion-accessible micropores, good electronic conductivity, and moderate oxygen doping, shows excellent performance in zinc-ion hybrid capacitor (ZIHC) with high specific capacity, remarkable energy density, and superior cycling life.

Summary: As a representative electrochemical energy storage device, supercapacitors (SCs) have higher energy density than traditional capacitors and better power density and cycle life than lithium-ion batteries, making them extensively used in energy storage. However, there is a lack of understanding of the thermal behaviors and thermal management systems of SCs, which this review aims to address. The review introduces the energy storage mechanisms of SCs and current investigations of thermal behaviors, including heat generation rates, experimental methods, heat generation rate models, and thermal runaway. It also provides an overview of current efforts in different cooling systems and discusses the challenges and future work directions for SCs in thermal behaviors and thermal management systems.
