“…Impressively, NS-OPC still has an energy density of 53.9 Wh kg –1 at a high power density of 6063.75 W kg –1 . The energy/power delivery of the NS-OPC device outperforms that of most previously reported carbonaceous ZHSCs. ,− After 10,000 cycles (Figure f), NS-OPC in the ZHSCs still maintained a high specific capacity of 75.4 mAh g –1 at a current density of 10 A g –1 , providing 86.2% capacity retention and ∼100% Coulomb efficiency for ultralong cycling performance. The overall performance exceeds that of previously reported materials and is summarized in Table S3.…”

“…Owing to their high energy density, high safety, high safety, low production cost, and flexibility of equipment, aqueous Zn-based batteries (AZBs) have broad prospects in power-grid-scale energy storage devices, electric vehicles, and wearable flexible devices. − These advantages are mainly attributed to their low redox potential, high theoretical specific capacity, nonflammability, and use of low-cost aqueous electrolytes. − However, their performance is limited by the lower power density and poor cycling life of Mn-based and V-based materials. By introducing a capacitive charge storage mechanism into the cathode of AZBs, the assembled Zn-ion hybrid supercapacitors (ZHSCs) use battery-type electrode materials for the anode and capacitor-type electrode materials for the cathode, inheriting the advantages of AZBs and supercapacitors. − Such hybrid capacitors store charges through the reversible adsorption–desorption reactions of anions on the cathode surface, while Zn 2+ dissolves/deposits on the Zn anode, providing an opportunity to efficiently and simultaneously improve the energy density, power density, and cycling life.…”

Zn-ion hybrid supercapacitors (ZHSCs) are emerging charge storage devices that inherit many of the advantages of supercapacitors and batteries. However, problems such as unsatisfactory cycling stability and low energy density need to be solved urgently, which can be accomplished by developing cathode materials with excellent properties. Herein, we report the development of performance-enhanced ZHSCs obtained by incorporating N and S heteroatoms into orange peel-based hierarchical porous carbon (NS-OPC) to facilitate Zn 2+ adsorption. The results of ex situ photoelectron spectroscopy and X-ray diffraction demonstrated the presence of −OH and Zn 2+ chemisorbed and Zn 4 SO 4 (OH) 6 •5H 2 O during charging and discharging, respectively. Density functional theory calculations show that double doping can promote the chemisorption/desorption kinetics of Zn 2+ and thus promote the electrochemical charge storage of C materials. Impressively, when used to assemble ZHSCs, the device still has an energy density of 53.9 Wh kg −1 , a high power density of 6063.75 W kg −1 , and an 86.2% capacity retention after 10,000 cycles. This study not only provides a reasonable technique for developing superior C-based electrode materials but also contributes to the understanding of the charge storage process in heteroatom-doped C materials.

Metal negatrode supercapattery (MNSC) is an emerging technology that combines the high energy storage capabilities of batteries with the high‐power delivery of supercapacitors, thereby offering promising solutions for various applications, such as energy storage systems, electric vehicles, and portable electronics. This review article presents a comprehensive analysis of the potential of MNSCs as a prospective energy storage technology. MNSCs utilize a specific configuration in which the negatrode consists of a metal or metal‐rich electrode, such as sodium, aluminum, potassium, or zinc, whereas the positrode functions as a supercapacitor electrode. The utilization of negatrodes with low electrochemical potential and high electrical conductivity is crucial for achieving high specific energy in energy storage devices, despite facing numerous challenges. The present study discusses the design and fabrication aspects of MNSCs, including the selection of appropriate metal negatrodes, electrolytes, and positrodes, alongside the fundamental operational mechanisms. Additionally, this review explores the challenges encountered in MNSCs and proposes solutions to enhance their performance, such as addressing dendrite formation and instability of metal electrodes.

Two-dimensional (2D) MoS 2 is one of the most representative materials of the transition metal dichalcogenide (TMD) family, which is mostly studied in the semiconductor 2H and metal 1T phases. However, the properties of the metalloid 1T′ phase remain unclear because of its immature preparation process and thermodynamic instability (metastable state). Herein, this study used theoretical calculations to discover the relationship and conditions for MoS 2 to transition between the 2H, 1T, and 1T′ phases. Meanwhile, charge and discharge voltages and current density were controlled by ion insertion technology, and then 1T′-MoS 2 with large size and definite morphology (the whole process was called "phase transition engineering") was prepared. The prepared 1T′-MoS 2 was used as the anode material for lithium-ion batteries. Compared with 2H-MoS 2 , the cyclic stability and specific capacity of 1T′-MoS 2 were greatly improved. In addition, phase transformation of natural molybdenite (2H-MoS 2 ) by phase transition engineering also yielded promising electrochemical properties. Consequently, phase transition engineering not only provided an opportunity for the phase transformation of TMDs of natural sulfide metals such as molybdenite but also offered an effective method to investigate the properties of 2D metastable polymorphic materials.
