“…In comparison with the similar anodes based on Ni 3 S 2 , as shown in Table 2, hierarchically interconnected Ni 3 S 2 nanofiber electrodes can deliver much enhanced capacities. 24,34,35,43,44 In order to clarify the Na + storage mechanism of hierarchically interconnected Ni 3 S 2 nanofibers, ex situ XRD results (taken from the third cycle) were measured at different charge and discharge conditions from stages a to f, as shown in Figure 5a,b. The fresh anode shows clear patterns of the Ni 3 S 2 phase (stage a), while the strong peaks located at 44.3°and 51.9°are ascribed to the Ni-foam substrate.…”

Direct growth of hierarchically interconnected Ni3S2 nanofibers as binder-free electrodes for high-performance sodium (Na+)-ion batteries was demonstrated by a facile one-step hydrothermal method on a nickel (Ni) foam. The hierarchically interconnected Ni3S2 nanofibers can effectively relieve volume expansion of Ni3S2 and shorten diffusion paths of Na+ ions that can enhance the high electronic conductivity during the electrochemical reaction, yielding high specific capacitance, excellent cycling stability, and outstanding rate capability. As a result, a high discharge specific capacity of 584.2 mAh g–1 at a current density of 0.2 A g–1 in the first sodiation process with a capacity retention of 91.9% after 100 cycles (retains 536.9 mAh g–1) can be achieved. The asymmetric Na+-ion capacitor based on the hierarchically interconnected Ni3S2 nanofibers as binder-free anode materials and the activated carbon as a cathode material exhibits high energy and power density. Interestingly, the conversion reaction mechanism of Na+-ion storage in the hierarchically interconnected Ni3S2 nanofibers was also investigated by the ex situ X-ray diffraction studies, suggesting a promising material as the binder-free electrode for advanced Na+-ion energy storage.

“…Due to the intermittency and instability, the rise of renewable energy sources has brought both huge opportunities and challenges to advanced electrical energy storage. − Lithium-ion batteries are usually the first choice for energy storage because of their outstanding performance. Nevertheless, considering the inflammability and possible toxicity, lithium batteries with flammable organic electrolyte are difficult to meet the safety and environmental demands. − In this case, aqueous batteries are quite suitable for large-scale energy storage, among which the lead–acid battery is a viable alternative.…”

“…By contrast, aqueous Zn-based batteries exhibit significant advantages due to abundant reserves, low cost, and environmental friendliness. Among them, Zn–Ni batteries are of particular interest by virtue of their high open-circuit voltage (∼1.75 V) compared to that of other rechargeable alkaline batteries (mostly ≤ 1.5 V). ,− Besides, unlike traditional lead–acid batteries that can only discharge at a low rate and Zn–Mn batteries (one of the most typical Zn-based batteries) whose depth of discharge (DOD) is severely confined by Mn cathode, Zn–Ni batteries can cycle stably at a high rate and a relatively deep DOD. , More balanced performance of the Zn–Ni batteries makes them more conducive to realizing large-scale energy supply.…”

In recent years, with the increasing application of lithium-ion batteries in energy storage devices, fire accidents caused by lithium-ion batteries have become more frequent and have arisen wide concern. Due to the safety of aqueous electrolyte, aqueous Zn-based batteries have attracted vast attention, among which Zn–Ni batteries stand out by virtue of their excellent rate performance and environmental friendliness. However, poor cycling life limits the application of Zn–Ni batteries. To figure out the main cause, a failure analysis of a practical Zn–Ni battery has been carried out. During the cycling of the Zn–Ni battery, the evolution of gas, the shape changing, and the aggregation of additive and binder of Zn anode can be observed. Combined with the finite element analysis, we finally reveal that the key factor of battery failure is the shape changing of the Zn anode caused by uneven current distribution and the dissolution of Zn. The shape changing of the Zn anode reduces the effective surface area of anode and increases the possibility of dead Zn, which makes the battery unable to discharge even in the presence of a large amount of Zn. These findings are helpful to deepen the understanding of the working and failure mechanisms of the Zn anode and provide effective guidance for subsequent research.

“…Therefore, innovative electrochemical energy storage technologies, such as Li-ion batteries (LIBs), Na-ion batteries, and supercapacitors, have been proposed to address this need [1][2][3][4][5][6][7][8]. LIBs are the most commonly used electrochemical energy storage devices available in the market today; these batteries play an indispensable role in daily life and are widely used in portable products, electric vehicles (EVs), and grid-scale energy storage systems [9][10][11][12][13][14][15]. However, the demand for energy densities beyond the capacity of conventional LIBs has increased.…”

All-solid-state Li-ion batteries (ASSLIBs) have been widely studied to achieve Li-ion batteries (LIBs) with high safety and energy density. Recent reviews and experimental papers have focused on methods that improve the ionic conductivity, stabilize the electrochemical performance, and enhance the electrolyte/electrode interfacial compatibility of several solid-state electrolytes (SSEs), including oxides, sulfides, composite and gel electrolytes, and so on. Garnet-structured Li 7 La 3 Zr 2 O 12 (LLZO) is highly regarded an SSE with excellent application potential. However, this type of electrolyte also possesses a number of disadvantages, such as low ionic conductivity, unstable cubic phase, and poor interfacial compatibility with anodes/cathodes. The benefits of LLZO have urged many researchers to explore effective solutions to overcome its inherent limitations. Herein, we review recent developments on garnet-structured LLZO and provide comprehensive insights to guide the development of garnet-structured LLZO-type electrolytes. We not only systematically and comprehensively discuss the preparation, element doping, structure, stability, and interfacial improvement of LLZOs but also provide future perspectives for these materials. This review expands the current understanding on advanced solid garnet electrolytes and provides meaningful guidance for the commercialization of ASSLIBs.
