Zinc iso-plating/stripping: toward a practical Zn powder anode with ultra-long life over 5600 h

Abstract

Zn powder with large-scale production and well-tunability is promising for aqueous Zn-ion batteries, but its extremely short lifespan seriously hinders the practical application. Herein, we disclose that Zn powder anode...

Zn Powder-Based Anodes for Aqueous Zn Metal Batteries: Strategies, Structures, and Perspectives

“…The protective layer of metal nanoparticles with stable active sites for the subsequent deposition may be the key to this effect. Similarly, Long et al reported a Zn@Bi composite Zn powder anodes and demonstrated that the stability of the Zn powder anodes decorated by heterogeneous metal nanoparticles was greatly improved . However, more research is needed to understand this mechanism.…”

“…Similarly, Long et al reported a Zn@Bi composite Zn powder anodes and demonstrated that the stability of the Zn powder anodes decorated by heterogeneous metal nanoparticles was greatly improved. 31 However, more research is needed to understand this mechanism. At present, the structural modification of Zn powders has not been paid much attention, and other modifications, such as surface carbon and oxide coating (Figure 2b), are worth exploring.…”

Crystallographic Manipulation Strategies toward Reversible Zn Anode with Orientational Deposition

“…This observation suggests that Zn powder, like Zn foil, can induce orientational deposition under specific conditions. [95] It can be anticipated that if the electrical conductivity of other 2D materials with a hexagonal structure meets the requirements for electrodeposition, they can also steer heteroepitaxial deposition along the Zn(002) plane. [96,97] The crystallographic orientation of electrodeposited Zn is strongly related to the crystal structure of depositing substrates.…”

Screening metal cation additives driven by differential capacitance for Zn batteries

“…Aqueous Zn ion batteries (ZIBs) have emerged as promising candidates for the next-generation sustainable large-scale energy storage systems, which is attributed to the abundant resources, cost-effectiveness, and high volumetric capacity (5850 mA h cm −3 ) of Zn anodes. 1–4 However, despite these advantages, the commercialization of ZIBs is still impeded by challenges related to uncontrolled Zn dendrite formation and the occurrence of notorious side reactions at the electrode/electrolyte interface. 5–8 Addressing these issues is crucial for unlocking the full potential of ZIBs and paving the way for their successful implementation in practical applications.…”
