“…The perseverance to address the daunting energy crisis and mitigate catastrophic climate change has emphasized the need for reliable, sustainable, and efficient energy storage systems to conserve fossil fuels and avoid environmental deterioration. Thus, there’s a crucial demand for effective and scalable storage solutions to supply energy consistently and effectively, as renewable energy sources like solar, tidal, and wind are intermittent. − In this regard, electrochemical energy storage systems have played a pivotal role in ensuring energy security and stability, especially in high-power supercapacitors (SCs) and high-energy rechargeable batteries. − However, standalone SCs have struggled with low energy density, which causes the user to be restricted in terms of storing large amounts of energy efficiently. So, hybrid supercapacitors (HSCs) have emerged as a solution, combining the strengths of SCs and rechargeable batteries to create devices with enhanced electrochemical properties. − These hybrid systems utilize a combination of capacitive and battery-type materials in their electrodes, utilizing cation transport to meet modern energy demands.…”

The demand for energy storage is exponentially increasing with the growth of the human population, which is highly energy intensive. This progress demands high-performing and reliable energy storage devices for storing and delivering charge efficiently. Hybrid ion supercapacitors are the most desirable electrochemical energy storage devices, owing to their versatile and tunable performance characteristics, as they are the optimized assembly of batteries (energy devices) and supercapacitors (power devices). In this regard, ammonium ion hybrid supercapacitors (AIHSs) have grabbed substantial research consideration in past years due to their notable advantages of affordability, safety, fast diffusion kinetics, ecofriendliness, high energy density, and unique tetrahedral structure with abundant charge carriers NH 4 + resources. Up to now, although there have been substantial research advancements in AIHSs over the past few years, including advancements in various electrode materials, device structures, and novel electrolytes, there remains a lack of comprehensive reviews that cover the recent developments and provide critical insights into this rapidly evolving field. Therefore, this review culminates with the fundamental principles, basic charge storage mechanisms, and approaches for enhancing the electrochemical performances of AIHSs, focusing on improving these parameters to improve energy density, specific capacitance, and longevity for the commercial success of hybrid ion capacitors, which are in the nascent stages of development. To the best of our knowledge, it is the first complete account of AIHSs from mechanism to recent developments.

In this study, nanosized zeolitic imidazolate framework‐8 (ZIF‐8) crystal has been produced on the universitetet i oslo‐66 (UiO‐66) metal–organic framework (MOF) to make core–shell structure using a layer‐by‐layer deposition method. In comparison to the pristine UiO‐66 and ZIF‐8, the core–shell MOF exhibits superior performance in terms of specific capacitance. This enhanced performance is attributed to its remarkable ability to facilitate the rapid diffusion of electrolyte ions through nanosized ZIF‐8 and enhance the electron transfer process involving the inner and outer metal ions within the UiO‐66@ZIF‐8 structure. Remarkably, the core–shell structure achieves an impressive specific capacitance of 588.8 F g−1 at a current density of 0.5 A g−1 using 1 m sulfuric acid (H2SO4) aqueous electrolyte. Additionally, the UiO‐66@ZIF‐8 core–shell material is demonstrated as a positive electrode, coupled with activated carbon (AC) derived from waste tissue paper serving as the negative electrode, in the fabrication of an asymmetric supercapacitor (ASC) device. At a power density of 400 W kg−1, this assembled asymmetric device delivers a notably high energy density of 53 Wh kg−1 along with a cyclic stability of 94.8% after 10 000 cycles. This study substantiates the superior performance of the UiO‐66@ZIF‐8 core–shell MOF structure as a highly effective supercapacitor electrode material, surpassing the performance of its pristine MOF counterparts.

The development of nanomaterials for energy storage and conversion has always been important. Layered double hydroxide (LDH) is a promising material due to its high capacity, tunable composition and easy synthesis. In this work, the morphology of NiCo‐LDH is tuned with surfactants including sodium dodecyl sulfate (SDS) and cetyltrimethylammonium bromide (CTAB), and investigated the correlation between morphology and electrochemical properties. NiCo‐LDH‐SDS with a layered structure exhibited a specific capacitance of 1004 C g−1 at 1 A g−1, which is higher than that of the needle‐like NiCo‐LDH‐CTAB (678 C g−1) and the rod‐like NiCo‐LDH (279 C g−1). Meanwhile, NiCo‐LDH‐SDS and NiCo‐LDH‐CTAB showed a reduction of 36 and 19 mV, respectively, in their overpotentials at 10 mA cm−2 compared to NiCo‐LDH. Contact angle and adhesive force measurements proved the influence of morphology on the interfacial properties that layered structure is favorable for the timely detachment of the bubbles. Therefore, rational morphology regulation of LDH can effectively alter the gas–liquid–solid interface and thereby accelerate the reaction kinetics. The connections between morphologies, bubbles releasing and electrochemical performance are well established in this work, which can be applied in the investigation of nanomaterials for energy‐related activities, especially the ones concerning bubbles releasing processes.
