“…[33] Wang et al fabricated a NiÀ Zn rechargeable battery, which was composed of cathodes (Co 3 O 4 @NiVÀ LDH nanowires), anodes (pre-depositing Zn onto the Cu foil) and electrolytes (1 M KOH), and exhibited high energy density up to 2.2 mWh cm À 2 and good cycling performance (up to 1500 cycles with 89 % capacity retention). [34] Although considerable progress has been made, the requirements of high capacity and long cycle time (generally more than 5000 cycles) haven't been fulfilled by most of the existing Ni/Zn batteries. .…”

Rechargeable alkaline zinc‐ion batteries (ZIBs) have gained extensive attention on account of their inexpensiveness, and high levels of safety and output voltage, but the lack of suitable cathode materials with high energy storage property and long cycle stability limits further development of ZIBs. Herein, we report an effective two‐step electrochemical approach to prepare Ni@NiO core‐shell dendritic architectures as cathode material for rechargeable alkaline ZIBs. Benefiting from the highly active NiO shell and unique core‐shell structure, this Ni@NiO electrode shows an excellent discharge capacity (0.112 mAh cm−2, at 4 mA cm−2) and a high rate capability (63.7 % capacity retention at 40 mA cm−2). Furthermore, the alkaline ZIBs with this Ni@NiO cathode also displays a high energy density of 0.193 mWh cm−2 and a remarkable power density of 65.0 mW cm−2.

“…. [33,34] Besides, the methods of these reported Nibased cathode material synthesis are relatively complicated and therefore are not conducive to commercialization. So, exploring simple, efficient, and practical synthesis methods of highperformance Ni-based cathodes materials is both challenging and of great significance.…”

“…The energy storage mechanism of Co 3 O 4 ‐based ZIBs in alkaline electrolytes are shown in Figure 1. [ 143,148–150 ] During the charging, Co 3 O 4 is converted to CoO 2 in two steps with CoOOH as the intermediate by reacting with OH − from the alkaline electrolyte; meanwhile, Zn(OH) 4 2− gains electrons to form metal Zn and release OH − into the electrolyte simultaneously. During the discharging, Zn(OH) 4 2− is generated from the reaction between Zn and OH − in the electrolyte; simultaneously, CoO 2 gains electrons to transform back to Co 3 O 4 in two steps.…”

Aqueous Zn battery turns to be a rational approach for next‐generation energy storage devices due to the high abundance, admirable theoretical capacity and excellent safety. As an emerging candidate of the ideal cathode material for Zn battery, Co‐based compounds have drawn increasing attentions because of the high output voltage, remarkable theoretical capacity and excellent redox property. In this review, a summary of recent developments of Co‐based cathodes in aqueous Zn batteries is presented, including Co3O4, Co(OH)2, NiCo2O4 and other Co‐based compounds. In addition to charge storage mechanisms, smart strategies including structural modulation, composition regulation, and defect engineering are systematically introduced, and their structure‐performance relationships are discussed in depth. Finally, limitations and proposed future work are demonstrated.

The Nickel-vanadium (NiV)-layered double hydroxide (LDH) was fabricated into a novel saturable absorber (SA) by the liquid phase exfoliation method and was utilized as the laser modulator for the first time. We investigated a passive Q-switched (PQS) Tm:YAG ceramic laser at 2 μm with the NiV-LDH SA. Under an absorbed pump power of 7.2 W, the shortest pulse width of 398 ns was obtained with an average output power of 263 mW and a pulse repetition frequency (PRF) of 101.8 kHz, corresponding to a single pulse energy to be 2.30 μJ. The results indicate that the NiV-LDH SA has great research potential in the field of laser modulation.
