Charge–discharge profiles of ion-exchanged MgFeSiO 4. A team of researchers from Kyoto University has demonstrated ion-exchanged MgFeSiO 4 as a feasible cathode material for use in high-energy-density rechargeable magnesium batteries. The ion-exchanged MgFeSiO 4 cathode materials provide a capacity of more than 300 mAh·g ?

Researchers at The Ohio State University have developed a novel strategy to improve the efficiency and performance of non-aqueous lithium-oxygen (Li-air) batteries. O 2 systems require an open system to obtain oxygen from the air; Li metal must also be used as the metal electrode to provide the lithium source. Earlier post.).
