New coating process allows faster production of battery electrodes

Researchers at Germany’s prestigious Karlsruhe Institute of Technology (KIT) have created a new coating process that produces electrodes for lithium-ion batteries at record speed. The researchers say the new process also improves the quality of electrodes and reduces production costs. When manufacturing battery electrodes, a thin paste of electrode material is applied to a copper… Read more »

MIT researchers demonstrate new way to make thin-film lithium-rich ceramic electrolytes

Researchers at MIT have come up with a new pulsed laser deposition technique to make thinner lithium electrolytes using less heat, which they say promises faster charging and potentially higher-voltage solid-state lithium-ion batteries. Key to the new technique for processing the solid-state battery electrolyte is alternating layers of the active electrolyte lithium garnet component (LLZO)… Read more »

UCLouvain discovers new solid-state material with high lithium diffusion coefficient

As research into solid-state lithium batteries continues, researchers at Belgium’s Université catholique de Louvain (UCLouvain) say they’ve found a new solid material, LTPS, in which lithium can travel more easily than in any other solid electrolyte. The results are published in the scientific journal Chem from Cell Press. Lithium ions are much less mobile in… Read more »
