Energy storage materials built from nano-sized molecular blocks

Molecules of the rare metallic element niobium can be used as molecular building blocks to design electrochemical energy storage materials. Mark Rambaran, Department of Chemistry at UmeƄ University, presents in his thesis ...

New hybrid electrolyte for high performance Li-ion batteries

Li-ion batteries (LIBs) are widely used batteries that support modern ITC society, including smartphones and EVs. LIBs are repeatedly charged and discharged by Li-ions passing back and forth between the positive and negative ...

Air-stability of sodium-based layered-oxide cathode materials

Sodium ion batteries are considered to be one of the most promising alternative systems to lithium-ion batteries, especially for large scale applications. Sodium-based transition-metal oxides with layered structure have been ...

'Hot' graphene reveals migration of carbon atoms

The migration of carbon atoms on the surface of the nanomaterial graphene was recently measured for the first time. Although the atoms move too swiftly to be directly observed with an electron microscope, their effect on ...
