Conclusion and perspectives The high cost of silver electrodes has restricted the widespread use of zinc-silver batteries, limiting their application primarily to areas where high specific energy and power are critically important, such as in lightweight medical and electronic devices, underwater equipment, torpedoes, and aerospace.
Due to smooth surface and few corners and edges solubility of the nanorods in alkaline medium is decreased which results in improved structural integrity of the material during charge/discharge cycling. The prepared material was investigated as anode material in silver zinc batteries with the aim to reduce the shape change of the electrodes.
Zinc is one of the most commonly used anode materials for primary batteries because of its low half-cell potential, high electrochemical reversibility, compatibility with acidic and alkaline aqueous electrolytes, low equivalent weight, high specific and bulk energy density, and high ultimate current.
This improved mechanical behavior resulted in improved cycle life and higher energy and power densities of the silver zinc batteries. We are thankful to Centralized Resource Laboratories, University of Peshawar for microscopy studies. Conceived and designed the experiments: SU AB FA RH.
In most technologies, zinc acts as the negative electrode, and the positive counter electrode may be silver, nickel hydroxide, mercury, or air. Other than zinc-based cells, the lithium-ion batteries are also available in a coin shape. The cells can be found from 5 to in diameter and 1 to in height.
