L'impression 3D dans des batteries, pour augmenter la puissance. A suivre.
“We think this is advantageous because you can decouple the solid-state versus liquid-state diffusion distance. The electrolyte is liquid, so as it’s channeling through this architecture, which is like a labyrinth, it has a solid surface available to it anywhere,” Greer explained.
Moreover, the design reduces tortuosity and shortens the physical path that ions must travel between the cathode and separator, thereby increasing the battery’s power density and allowing it to release its stored energy much faster.
