Exploring a new avenue for the manufacture of magnesium batteries to complement lithium models

"magnesium batteries with manganese compound increased capacities up to 3.1 volts, which means that their energy density, at the laboratory scale, is 335 Wh/kg, representing 60% of lithium-ion batteries' energy density. This is a breakthrough, as in previous studies a maximum of 2.2 volts was never exceeded. However, they also found that in charging and discharging cycles the batteries saw their initial capacity cut in half. As Ortiz argues, "with new scientific strategies, the initial capacity might be recovered"
