Magnesium is far more common and therefore less expensive, and it’s not prone to breaches in its internal structure but magnesium batteries won’t be commercially competitive until they can store and discharge large amounts of energy. Cathode and electrolyte materials have been a stumbling block. Through the optimal combination of organic carbonyl polymer cathodes and Mg-storage-enabling electrolytes, a team of researchers in the US (University of Michigan, industry partner) has demonstrated that high specific energy, power, and cycling stability that are rarely seen in Mg batteries. They showed that in lean electrolyte conditions, the Mg2+-storing organic cathodes deliver the same energy while using ∼10% of the amount of electrolyte needed for the MgCl-based counterparts…read more..
