3-D printing the next generation of batteries
July 30, 2018 by Emily Durham, Carnegie Mellon University
Additive manufacturing, otherwise known as 3-D printing, can be used to manufacture porous electrodes for lithium-ion batteries—but because of the nature of the manufacturing process, the design of these 3-D printed electrodes is limited to just a few possible architectures. Until now, the internal geometry that produced the best porous electrodes through additive manufacturing was what's known as an interdigitated geometry—metal prongs interlocked like the fingers of two clasped hands, with the lithium shuttling between the two sides.
