“…12 Composition modification of the electrode and the electrolyte is generally used for inhibiting metal corrosion in addition to structure optimization. 13 To inhibit hydrogen evolution reaction, Mg can be alloyed with other metals of Al, Zn, Mn, [14][15][16][17][18][19] improving the performance of Mg-air batteries. Hopkins et al 20 suppressed open-circuit corrosion by displacing electrolyte from the electrode surface with a nonconducting oil during battery standby.…”

Mg-air battery is a promising candidate as power supply because of high specific energy, stable discharge voltage, long storage life and friendly environment. However, the corrosion and passivation of Mg remains unresolved as well as oxygen supply, resulting in increase of electrode overpotential. Here, a type of oxygen electrode is present for Mg-oxygen battery, where hydrogen peroxide can directly and indirectly form hydroxide ions by means of nickel foam sandwiched with MnO 2 and Fe/C. In optimization of electrolyte concentration, inhibitor and electrode structure, Na 3 VO 4 is superior to Na 3 PO 4 and La(CH 3 COO) 3 inhibiting Mg corrosion, the optimal NaCl concentration is obtained for Mg-air battery, and the oxygen electrode can effectively improve the performance of Mg-oxygen battery. The results show that the Mg-oxygen battery employing 0.3 wt.% H 2 O 2 as oxygen supply and 15.5 wt.% NaCl as the electrolyte can stably run for more than 7 h, and the battery is discharged above 1 V at the current density of 25 mA cm −2 . The findings of Mg-oxygen battery can be available for power supply in the anaerobic or anoxic environment.

Monitoring through satellite data, in situ (including spectrometer data, GPS, thermal camera) , open data, data from various devices and Unmanned Aerial Vehicles (UAV) in the selected anthropogenic sites is of extremely high ecological importance for tracking natural processes, the consequences of climate changes and the creation of a useful model for the analysis of spectral characteristics based on machine learning. The timeliness of the data and the spatial extent of the observed objects allow satellite information to be reliable in monitoring and making predictions about the risk and potential risk of natural disasters, rise of average air temperatures and anthropogenic pollution. The sites were pre-marked based on open data from Non-Governmental Organizations (NGOs) and administration. Data from the Multispectral Instrument (MSI) of the Sentinel 2 platform and SAR of the European Space Agency's Copernicus program, spectrometer (380 nm to 780 nm) and drone data were used. Landsat sensors and data from Sentinel 3 (EUMETSAT) were used to calculate the surface temperature of renewable energy sites such as photovoltaic parks. Data from different years were used in order to track the studied territories according to NUTS2. The result is the development of a useful hybrid model for spectral analysis and tracking of spatial dynamics and surface changes of objects of interest based on satellite and field surveys. Data from the ground mobile and autonomous weather station AWG 1, powered by an environmentally friendly magnesium-air battery was improved specifically for the project. Another important task is the creation of an energy atlas for the benefit of the Earth's Digital Twins. The data is part of an open data catalog of the NGO Eco Global Monitoring TA2.

“…Most recently, Milusheva et al [30] showed the possibility of the utilisation of the lead-air electrochemical system as a power source. This system consisted of a standard lead electrode and H 2 SO 4 electrolyte used in the lead-acid battery and a gas diffusion electrode which was sufficiently stable in the sulphuric acid electrolyte.…”

In the dynamic realm of sustainable energy storage technologies, the global research landscape presents myriad scientific and economic challenges. The erratic growth of renewable energies alongside the phasing out of conventional power plants poses a significant hurdle in maintaining a stable balance between energy supply and demand. Consequently, energy storage solutions play a pivotal role in mitigating substantial fluctuations in demand. Metal–air batteries, distinguished by their superior energy density and enhanced safety profile compared to other storage devices, emerge as promising solutions. Leveraging the well-established lead–acid battery technology, this study introduces a novel approach utilising open-cell foam manufactured through the Excess Salt Replication process as an anode for lead–air battery cells. This innovation not only conserves lead but also reduces battery weight. By employing a 25% antimonial lead alloy, open-cell foams with diameters ranging from 2 mm to 5 mm were fabricated for the antimonial lead–air battery. Preliminary findings suggest that the effective electrical conductivity of primary battery cells, measured experimentally, surpasses that of cells composed of the same dense, non-porous antimonial lead alloy. This improvement is primarily attributed to their extensive specific surface area, facilitating oxidation–reduction reactions. A correlation between effective electrical conductivity and cell diameter is established, indicating optimal conductivity achieved with a 5 mm cell diameter. These results underscore the feasibility of implementing such an electrical system.
