Defect-free graphene might solve lithium-metal batteries' dendrite problem

Wed, 02/13/2019 - 11:58
The formation of dendrites on the metal electrodes of lithium metal batteries causes safety and performance concerns. To avoid dendrites, researchers are experimenting with new battery electrolyte chemistries, new separator technologies, and new physical hosts for the lithium metal. Researchers now have discovered a key design rule for Li metal batteries: If you want to suppress dendrites, you have to use a defect-free host. More generally, carbon defects catalyze dendrite growth in metal anodes.
