A research team, supported by the Swiss National Science Foundation (SNF), has produced experimental battery components based on sodium and magnesium to provide alternatives to the current lithium batteries.

The recent research, led by Arndt Remhof of the Swiss Federal Laboratories for Materials Science and Technology (Empa), aims to find new materials that can be used in rechargeable batteries and eventually tackle problems existing in lithium batteries, such as the limited availability of the raw material itself as well as the inflammability and other safety issues.

Baked leaf leads to better sodium batteries

Scientists from the University of Maryland have used an anode made of carbonised oak leaf to boost performance of a sodium battery.

Using the ‘leaf’ anode, scientists found a battery could hold 90% of its charge after 200 cycles and kept its charge efficiency at around 75%. The results were unveiled in a paper published in the journal ACS Applied Materials Interfaces.
