Are we finally getting 3D-printed batteries?

Dry printing of battery electrodes can avoid the toxic solvents and industrial ovens involved in the conventional wet process, which means a smaller physical and environmental footprint, but engineers have struggled to make it work at the needed scale and speed. Now a company called Sakuu says it has cracked the code. It is selling machines it claims will be able to print multiple battery chemistries, at competitive costs and speeds. I talk with CTO Karl Littau about the details and what 3D printing could enable in future batteries. This is a public episode.
