Scientists in Japan have demonstrated sodium-ion batteries using hard carbon microlattices, produced with an inexpensive 3D printer. In addition to reducing the battery size and slashing manufacturing costs, the resulting anode allows fast transportation of energy-generating ions.Sodium-ion batteries offer advantages in terms of raw material costs and safety, but there is still room for improvement if they are to supersede the ubiquitous lithium-ion technology. Now, new research promises to lower manufacturing costs and improve the performance of sodium-ion batteries by virtue of micro-architected ...Den vollständigen Artikel lesen ...
