Fast-charging and high-capacity nanomesh-based cathodes for Li-ion batteries

Mon, 07/06/2020 - 17:07
The concept of nanostructuring of battery electrodes is not new; it has been frequently employed to improve the charging speed and, in some cases, stability of Li-ion electrodes. Researchers now demonstrated 3D-interconnected Ni nanowire meshes as current collectors and structural scaffolds for building nanostructured Li-ion electrodes. This material exhibits a semi-ordered structure and is characterized by some of the highest combined porosity and surface-to-volume ratio among macroporous metals.

The superiority of single-layer molybdenum disulfide for water desalination

Fri, 07/03/2020 - 10:25
Researchers show that a nanoporous MoS2 membrane allows a higher water flux compared with other 2D materials such as graphene, boron nitride and phosphorene. The team dug deeply into the physical reasons behind why MoS2 performed better than other two-dimensional materials in water desalination processes. Through molecular dynamics simulation, they found out that water density near a MoS2 membrane is lower compared to that near other materials, which indicates that water molecules were more likely to transport through the membrane instead of accumulating around it.
