Hybrid supercapacitors (HSCs) are a novel type of supercapacitor composed battery-type electrodes and capacitor-type electrodes, which have directly transformed the global energy landscape. On one hand, they can replace clean sources that heavily dependent on climatic conditions in specific regions, thereby enhancing effective utilization intermittent sources. other with their high density akin to secondary batteries long lifespan power characteristic supercapacitors, perfectly bridge gap between supercapacitors. This article reviews fundamental storage principles HSCs highlights latest optimization strategies for based transition metal oxides (TMOs) carbon over past two years. These include heteroatom doping, heterostructured materials, nanocomposites, metal–organic frameworks (MOF). Finally, prospects future research directions discussed.

Zinc–iodine batteries (ZIBs) are promising candidates for ecofriendly, safe, and low-cost energy storage systems, but polyiodide shuttling the complex cathode fabrication procedures have severely hindered their broader commercial usage. Herein, a protocol is developed using phospholipid-like oleylamine molecules scalable production of Langmuir–Blodgett films, which allows facile preparation ZIB cathodes in less than 1 min. The resulting inhomogeneous continuous conversion iodine. Moreover, amine group molecule at capable producing [OA*I+]I3– charge-transfer complexes with iodine, facilitates rapid migration iodine results highly reversible process. Consequently, as-prepared ZIBs can deliver over 2000 cycles 0.5 mA cm–2 capacity retention 75.3%. This work presents novel, straightforward, efficient method construction ZIBs.

The preparation of porous carbon is constrained by the extensive use and detrimental impact activators dopants. Therefore, developing green efficient strategies that leverage intrinsic properties pretreatment materials to achieve self-activation self-doping particularly crucial for materials. Herein, potassium histidine was utilized as molecular salt precursor, attaining streamlined through a one-step carbonization process enables self-activation, self-doping, self-templating. More interestingly, temperature significantly impacts structure precursors, heteroatoms, electrochemical performance. designed electrodes exhibit high accessibility electrolyte ions effective ion-electron transport channels. optimal material (KHis800) has an excellent mass-specific capacitance 305.2 F g

The application of 3D printing technology in fabricating quasi-solid-state micro-supercapacitors (MSCs) offers inherent benefits programmable structural design and high-mass-loading electrode fabrication. Nevertheless, the absence high-performance printable inks sluggish ion transport within thick electrodes present significant challenges to their practical charge storage capabilities. Here, a new NiCo2S4-based nanocomposite ink with excellent rheological properties has been successfully developed structure MSCs is rationally engineered through direct-ink-writing technology. Beneficial from firmly anchored NiCo2S4 nanoparticles on reduced graphene oxide (rGO) ordered micropores, serrated architectures provide abundant reaction sites exhibit enhanced transport. Consequently, triple-layer-serrated can deliver high areal capacitance up 416.7 mF cm−2. In comparison latticed counterparts, capacitances single-, double-, triple-layer are amplified by 127.1%, 349.8%, 585.9%, respectively (under 1 mA cm−2). This study novel insights into cross-scale materials for capacitance, promoting integration flexible portable electronic devices.
