Story highlights
- New material for sodium ion batteries comprising graphene and phosphorene
- Materials display greater conductivity and stability
- Applications in large-scale energy storage
(2D Materials Magazine)- Researchers at have developed a new material that comprises interspersed layers of graphene and phosphorene.
The researchers have demonstrated that the materials have greater stability, are more conductive and possess a higher capacity anode for sodium ion batteries that previous materials.
Application in sodium ion batteries for large-scale energy storage are feasible.
Yi Cui and fellow researchers at Stanford University in California have developed materials that use graphene layers as an elastic buffer and function as an electrical highway, allowing charge to get in and out faster.
