Special Issue Information

Dear Colleagues,

Metal-ion capacitors as newly developed hybrid electrochemical energy storage (EES) systems are composed of a battery-type electrode and supercapacitor-type electrode, coupled with the redox reaction and electric double layer behavior, which could achieve the desired peculiarities of a high energy density, large power density and long lifespan.  However, due to the incompatibleness of two different energy storage mechanisms, the electrochemical performances are unsatisfactory. Moreover, the construction of advanced metal-ion capacitors is mainly limited by key bottlenecks such as the kinetics mismatching between electrodes, unclear storage mechanism of electrodes and uncontrollable pre-metalation technology. To address these concerns, this edition discusses the technologies, systems and applications of metal-ion capacitors.

Topics of interest include but are not limited to:

  • Energy storage mechanism of metal-ion capacitors;
  • Key technologies of metal-ion capacitors;
  • Pre-metalation methods;
  • Electrolytes;
  • Advanced characterizations for metal-ion capacitors;
  • Cell structure designs.

Lithium-ion capacitors (LICs) are emerging as promising hybrid energy storage devices that combine the high energy densities of lithium-ion batteries (LIBs) with high power densities of supercapacitors (SCs).

Lithium-ion capacitors (LICs) are emerging as promising hybrid energy storage devices that combine the high energy densities of lithium-ion batteries (LIBs) with high power densities of supercapacitors (SCs). Nevertheless, the development of LICs is hindered by the kinetic imbalances between battery-type anodes and capacitor-type cathodes. To address this issue, honeycomb-like N-doped carbon matrices encapsulating Co1−xS/Co(PO3)2 heterostructures were prepared using a simple chemical blowing-vulcanization process followed by phosphorylation treatment (Co1−xS/Co(PO3)2@NC). The Co1−xS/Co(PO3)2@NC features a unique heterostructure engineered within carbon honeycomb structures, which efficiently promotes charge transfer at the interfaces, alleviates the volume expansion of Co-based materials, and accelerates reaction kinetics. The optimal Co1−xS/Co(PO3)2@NC composite demonstrates a stable reversible capacity of 371.8 mAh g−1 after 800 cycles at 1 A g−1, and exhibits an excellent rate performance of 242.9 mAh g−1 even at 8 A g−1, alongside enhanced pseudocapacitive behavior. The assembled Co1−xS/Co(PO3)2@NC//AC LIC delivers a high energy density of 90.47 Wh kg−1 (at 26.28 W kg−1), a high power density of 504.94 W kg−1 (at 38.31 Wh kg−1), and a remarkable cyclic stablitiy of 86.3% retention after 5000 cycles. This research is expected to provide valuable insights into the design of conversion-type electrode materials for future energy storage applications. Full article

Transition metal phosphate is the prospective electrode material for supercapacitors (SCs). It has an open frame construction with spacious cavities and wide aisles, resulting in excellent electric storage capacity. However, the inferior rate behavior and cycling stability of transition metal phosphate materials in alkaline environments pose significant barriers to their application in SCs. Herein, Ni11(HPO3)8(OH)6/Co3(HPO4)2(OH)2 heterostructured materials synthesized through a one-step hydrothermal process exhibiting remarkable rate capability coupled with exceptional cycling endurance. Ni11(HPO3)8(OH)6/Co3(HPO4)2(OH)2 samples exhibit a micron-scale structure composed of sheet-like compositions and unique pore structure. The multistage pore structure is favorable for promoting the diffusion of protons and ions, enhancing the sample’s electrochemical storage capacity. Upon conducting electrochemical tests, it was observed that Ni11(HPO3)8(OH)6/Co3(HPO4)2(OH)2 composite electrode surpassed both the standalone Ni11(HPO3)8(OH)6 and Co3(HPO4)2(OH)2 electrode, achieving a remarkable specific capacity of 163 mAh g−1 with exceptional stability and efficiency at 1 A g−1. Notably, this electrode also exhibits superior rate performance, maintaining 82.5% and 71% of its original full capacity even at 50 A g−1 and 100 A g−1, respectively. Furthermore, it demonstrates superior stability in cycling, retaining a capacity of 92.7% at 10 A g−1 after 5000 cycles. Moreover, Ni11(HPO3)8(OH)6/Co3(HPO4)2(OH)2 and porous carbon (PC) were assembled into a hybrid supercapacitor (HSC). Electrochemical tests reveal an impressive power density of up to 36 kW kg−1 and an exceptional energy density of up to 47.4 Wh kg−1 for the HSC. Moreover, Ni11(HPO3)8(OH)6/Co3(HPO4)2(OH)2//PC HSC exhibits robust capacity retention stability of 92.9% after enduring 10,000 cycles at 3 A g−1, demonstrating its remarkable durability. This work imparts viewpoints into the design of transition metal phosphate heterostructured materials. Full article

The growing demands for electrochemical energy storage systems is driving the exploration of novel devices, with lithium-ion capacitors (LICs) emerging as a promising strategy to achieve both high energy density and fast charge capability. However, the low capacitance of commercial activated carbon (AC) cathode based on anion absorption/desorption limits LIC applications. Herein, commercial graphite is proposed as the cathode to construct an innovative AC (−)//graphite (+) system. The graphite cathode functions as anion hosting, allowing reversible intercalation/de-intercalation of anions into/from its interlayers. The as-designed AC (−)//graphite (+) full cell achieves stable cycling with 90.6% capacity retention after 200 cycles at 0.1 A g−1 and a prolonged lifespan with 87.5% capacity retention after 5000 cycles at 0.5 A g−1 with the upper cut-off voltage of 5.0 V, yielding a high average Coulombic efficiency (CE) of 99.3%. Moreover, the full cell exhibits a high energy density (>200 Wh kg−1) and power density of 7.7 kW kg−1 (calculated based on active mass in both electrodes). These performances exceed most LICs based on anions absorption/desorption on the surface of AC cathodes. This work explores an effective electrode revolution with the assistance of anion intercalation/de-intercalation chemistry for developing novel LICs with high energy and power densities. Full article

Modern research has made the search for high-performance, sustainable, and efficient energy storage technologies a main focus, especially in light of the growing environmental and energy-demanding issues. This review paper focuses on the pivotal role of biomass-derived carbon (BDC) materials in the development of high-performance metal-ion hybrid supercapacitors (MIHSCs), specifically targeting sodium (Na)-, potassium (K)-, aluminium (Al)-, and zinc (Zn)-ion-based systems. Due to their widespread availability, renewable nature, and exceptional physicochemical properties, BDC materials are ideal for supercapacitor electrodes, which perfectly balance environmental sustainability and technological advancement. This paper delves into the synthesis, functionalization, and structural engineering of advanced biomass-based carbon materials, highlighting the strategies to enhance their electrochemical performance. It elaborates on the unique characteristics of these carbons, such as high specific surface area, tuneable porosity, and heteroatom doping, which are pivotal in achieving superior capacitance, energy density, and cycling stability in Na-, K-, Al-, and Zn-ion hybrid supercapacitors. Furthermore, the compatibility of BDCs with metal-ion electrolytes and their role in facilitating ion transport and charge storage mechanisms are critically analysed. Novelty arises from a comprehensive comparison of these carbon materials across metal-ion systems, unveiling the synergistic effects of BDCs’ structural attributes on the performance of each supercapacitor type. This review also casts light on the current challenges, such as scalability, cost-effectiveness, and performance consistency, offering insightful perspectives for future research. This review underscores the transformative potential of BDC materials in MIHSCs and paves the way for next-generation energy storage technologies that are both high-performing and ecologically friendly. It calls for continued innovation and interdisciplinary collaboration to explore these sustainable materials, thereby contributing to advancing green energy technologies. Full article

Aqueous zinc-ion hybrid capacitors (ZIHCs) have emerged as a promising technology, showing superior energy and power densities, as well as enhanced safety, inexpensive and eco-friendly features. Although ZIHCs possess the advantages of both batteries and supercapacitors, their energy density is still unsatisfactory. Therefore, it is extremely crucial to develop reasonably matched electrode materials. Based on this challenge, a surge of studies has been conducted on the modification of carbon-based electrode materials. Herein, we first summarize the progress of the related research and elucidate the energy storage mechanism associated with carbon-based electrodes for ZIHCs. Then, we investigate the influence of the synthesis routes and modification strategies of the electrode materials on electrochemical stability. Finally, we summarize the current research challenges facing ZIHCs and predict potential future research pathways. In addition, we suggest key scientific questions to focus on and potential directions for further exploration. Full article

Abstract: The development of energy storage devices is the main driving force behind portable electronics and electric vehicles. Among these devices, secondary batteries and supercapacitors stand out as two of the most important energy storage systems due to their inherent advantages. Thanks to their distinctive energy storage mechanisms secondary batteries possess high energy density, while supercapacitors offer ultrahigh power density and excellent cycling stability.There is a pressing need for advanced energy storage devices that combine both high energy density and power density. Hybrid supercapacitors (HSCs), comprising a battery-type electrode and a capacitor-type electrode, leverage the superiorities of both batteries and supercapacitors. HSCs are considered promising next-generation energy storage devices, although they still face certain challenges. This review will begin by introducing the working mechanism of HSCs and addressing the challenges they face. Subsequently, the development of HSCs will be examined in detail. Finally, future research directions will be proposed. The aim of this review is to provide a comprehensive overview of HSCs and offer guidance for future research in this field.
