Washington, September 23 (ANI): In a new research, scientists have determined that a splash of graphene can improve battery materials.
Researchers would like to develop lithium-ion batteries using titanium dioxide, an inexpensive material.
But titanium dioxide on its own doesn't perform well enough to replace the expensive, rare-earth metals or fire-prone carbon-based materials used in today's lithium-ion batteries.
To test whether graphene, a good conductor on its own, can help, PNNL's (Pacific Northwest National Laboratory) Gary Yang and colleagues added graphene, sheets made up of single carbon atoms, to titanium dioxide.
When they compared how well the new combination of electrode materials charged and discharged electric current, the electrodes containing graphene outperformed the standard titanium dioxide by up to three times.
Graphene also performed better as an additive than carbon nanotubes. (ANI)
