Battery Technology

                                                                                   Charging and discharging a lithium-ion battery multiple times causes significant change to the volume of the anode, reducing the battery capacity and battery life. Now researchers from GIST in Korea have developed a method to strengthen the anode, making it more resilient against volume changes. The anode can be modified irrespective of its material…

As we move towards a more energy-efficient society, the need for high-capacity, cost-effective batteries is greater than ever. Magnesium is a promising material for such solid-state batteries owing to its abundance, but its practical application is limited by the poor conductivity of magnesium ions (Mg2+) in solids at room temperature. Recently, researchers from Japan have…
