Carbon forms have contributed substantially to the development of nanoscience and nanotechnology. Soon after their discovery, fullerenes, carbon nanotubes, and graphene have demonstrated to be versatile nanocarbons that ...

The supply of battery-grade nickel to produce positive electrodes of sodium-ion batteries may soon become insufficient. For this reason, it is crucial to find new electrode materials that minimize its use or even fully ...

The anode of Na-ion batteries under development is dominated by carbon materials, especially hard carbons with poorly organized structures. The production of carbon materials by pyrolysis of food waste is less expensive ...

Layered oxides are successful cathode materials for sodium-ion batteries. Many of these oxides show interesting kinetic behavior but have poor structural stability. To overcome this limitation, an alternative material ...

It is known that a certain amount (x) of lithium can be reversibly (de)inserted in the spinel-type LixMn2O4, while the structure is preserved. In contrast to lithium-containing spinel, it is believed that the sodium-cont ...

Having in mind the remarkable economic and environmental issues involved in the presence of nickel and cobalt metals in electrode compositions, new Na0.67Mg0.05Fe0.1NixMn0.85-xO2 (x= 0.0, 0.05, 0.1, 0.15) with a P2 type ...

This research highlights the efficacy of NaNbO3 as a coating for P2-Na2/3Ni1/3Mn2/3O2 cathodes in sodium-ion batteries. The coating enhances the kinetic behavior and cyclability of the electrochemical cells, as shown by ...

The current study explores the synthesis and electrochemical performance of potassium birnessite as a cathode material for sodium-ion batteries (SIBs), achieved through partial ion exchange resulting from partial potassium ...

Amorphous alumina (a-Al2O3)-coated Na3VAl(PO4)3 samples are prepared by a low-cost, easily scalable, and environmentally friendly sol-gel process. X-ray diffraction reveals no significant structural changes after deposition. ...

Microwave calcination is proposed as an alternative to conventional heating in an electric furnace to provide high performance electrodes for sodium-ion batteries. The short annealing time was compatible with the preparation ...
