“…Choban with co-authors [66] presented a methanol/O 2 fuel cell with acidic (0.5 M H 2 SO 4 ) and alkaline (1 M KOH) electrolytes. Later this dual-electrolyte (acidic and alkaline) idea was adapted to different electrode batteries such as Al-air [67][68][69][70], Zn-air [68,71,72], Mg-air [68,73], Zn-PbO 2 [74][75][76], Zn-Br 2 [77], etc. However, the battery working time and efficiency of this battery cell type are limited by both the electrolyte neutralization reaction and ion diffusion.…”

As the world moves towards sustainable and renewable energy sources, there is a need for reliable energy storage systems. A good candidate for such an application could be to improve secondary aqueous zinc–manganese dioxide (Zn-MnO2) batteries. For this reason, different aqueous Zn-MnO2 battery technologies are discussed in this short review, focusing on how electrolytes with different pH affect the battery. Improvements and achievements in alkaline aqueous Zn-MnO2 batteries the recent years have been briefly reviewed. Additionally, mild to acidic aqueous electrolyte employment in Zn-MnO2 batteries has been described, acknowledging their potential success, as such a battery design can increase the potential by up to 2 V. However, we have also recognized a novel battery electrolyte type that could increase even more scientific interest in aqueous Zn-MnO2 batteries. Consisting of an alkaline electrolyte in the anode compartment and an acidic electrolyte in the cathode compartment, this dual (amphoteric) electrolyte system permits the extension of the battery cell potential above 2 V without water decomposition. In addition, papers describing pH immobilization in aqueous zinc–manganese compound batteries and the achieved results are reported and discussed.

“…An inexhaustible supply of air is connected to the cathode to provide oxygen. There are eight different types of metal–air batteries, including lithium–air, sodium–air, potassium–air, zinc–air, magnesium–air, calcium–air, aluminium–air, and iron–air batteries [36]. Lithium–air batteries have the most specific energy among these batteries, but they are very flammable and their use is not safe.…”

This paper presents an improved levellized cost of storage (ILCOS) index for comparing various storage technologies. The ILCOS is a modified index based on the conventional levellized cost of storage (LCOS) that includes the effect of daily self‐discharge. This index calculates the total cost of discharged energy for a storage system over its lifetime. Comparing the conventional LCOS and the proposed ILCOS metrics indicates that the ILCOS is a more accurate index for the economic analysis of storage technologies. Also, this paper introduces an algorithm by using the ILCOS index for selecting the optimum storage technology in any individual application. The algorithm inputs are the needed discharge time, the required stand‐by time, and the technical and economical characteristics of storage systems; the output is the optimum storage technology. Based on the discharge time, this algorithm investigates the storage technology in three categories: short‐duration, medium‐duration, and long‐duration applications. Any storage system that has the minimum ILCOS is the economically winning technology. Given the characteristics of the existing storage technologies, the case study shows that for long‐duration applications, the pumped hydroelectric storage (PHS) is the best option. Also, vanadium redox flow battery (VRFB) and lead‐acid (PbA) batteries are the most economic storages for medium‐duration applications.
