New Type Of Graphene Paves The Way For Sustainable Sodium Batteries

Lithium-ion batteries are a cornerstone of our technology due to their energy storage capabilities. But lithium itself is not that great when one considers the environmental and monetary costs of its production. A better alternative would be sodium, which is abundant on Earth but making sodium batteries is not without its difficulties. However, one of those might have been sorted.

Researchers from Chalmers University of Technology have been able to build high-performance electrode materials for sodium batteries with a special type of graphene. The battery shows energy capacity very close to what can be found in standard lithium batteries. The breakthrough is published in Science Advances.

In lithium batteries, the anode is made of graphite, the material in a pencil lead, which is layer upon layer of graphene….
