Scientists tackle power and stability concerns to develop cathode for sodium, magnesium and aluminium batteries

Fri, 11/01/2019 - 12:19 -- Paul Crompton

Scientists at the University of Maryland have re-designed battery cathodes to make more efficient, stable and affordable rechargeable sodium, magnesium and aluminium batteries.

The researchers, backed by an international group of collaborators, have used polymeric hexaazatrinaphthalene (PHATN), based on the organic compound pyrazine, as a high-capacity, fast-charging cathode material.

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.
