Review—Status of Zinc-Silver Battery

Abstract

As the capacity reach as high as 350 Wh•kg −1 and 750 Wh•L −1 , zinc-silver batteries are widely used in military, aerospace and other fields because of their high specific energy and discharging rate, together with their safety and reliability. In this paper, the researches progresses of silver oxide electrode in eliminating high plateau stage, improving thermal stability and its structure are reviewed. Also the corrosion inhibitor of zinc electrode to prevent hydrogen evolution is summarized. In addition, the technical progress of battery separator is presented. The developing trends of the zinc silver battery are prospected.

α-NiO/Ni(OH)2/AgNP/F-Graphene Composite for Energy Storage Application

“…On the other hand, a repeating charge/discharge cycle at the relatively high current density of 8.3 A g –1 leads to a higher oxidation status of silver like Ag 2 O 3 caused by the OER, which results in an additional reduction reaction of Ag 2 O 3 to AgO along with AgO to Ag 2 O, and Ag 2 O to Ag at the subsequent discharging process ( Figure 6 d). 40 − 42 …”

“…The discharge voltage profile reaches a plateau at −0.5 and −1.0 V (vs Ag/AgCl), where each reduction of AgO to Ag 2 O and Ag 2 O to Ag most likely takes place (Figure c). On the other hand, a repeating charge/discharge cycle at the relatively high current density of 8.3 A g –1 leads to a higher oxidation status of silver like Ag 2 O 3 caused by the OER, which results in an additional reduction reaction of Ag 2 O 3 to AgO along with AgO to Ag 2 O, and Ag 2 O to Ag at the subsequent discharging process (Figure d). − …”

2020 Roadmap on Zinc Metal Batteries

“…[1,2] Moreover, benefited from the advantages of stable discharge potential, high voltage accuracy and reliable safety, ZnÀ Ag batteries show great potential in energy storage market. [3][4][5] However, the manufacturing cost of ZnÀ Ag batteries is extraordinarily high because of the high price of Ag resource. Hence, current ZnÀ Ag batteries is mainly applied in military and aerospace fields ( e. g., torpedo, missile, and space vehicle).…”

“…Zinc‐silver (Zn−Ag) battery is one of the widely studied alkaline battery with high theoretical energy density of 350 Wh kg −1 and 750 Wh L −1 [1,2] . Moreover, benefited from the advantages of stable discharge potential, high voltage accuracy and reliable safety, Zn−Ag batteries show great potential in energy storage market [3–5] . However, the manufacturing cost of Zn−Ag batteries is extraordinarily high because of the high price of Ag resource.…”

Entropy and Enthalpy Effects on Metal Complex Formation in Non-Aqueous Solvents: The Case of Silver(I) and Monoamines

“…Silver is currently considered as a “low risk supply” material [ 19 ], nevertheless, its demand is increasing for several applications, such as nanomaterial synthesis [ 20 ], optical [ 21 ], catalytic [ 22 ], energy storage [ 23 ], adsorptive and medical technologies [ 24 , 25 , 26 ]. The synergic effect of increasing demand and supply shortages [ 27 , 28 ] stimulated the development of technologies aimed also at recovering silver from secondary sources, such as e-waste [ 29 ].…”
