Can 3D Printing Finally Make Solid-State EV Batteries Practical?

San Jose-based 3D-printing startup Sakuu (originally KeraCel) reckons it may have finally cracked the code and discovered the holy grail that could at last make solid-state batteries a practical reality in everything from microelectronics to big electric vehicles. We explained the many virtues of solid-state batteries here, including their inherent fire safety, insusceptibility to freezing, improved energy density, etc. Sakuu’s advance is as much a 3D-printing breakthrough as it is one of battery chemistry, and its Swift Print battery technology promises to enable production of batteries in custom form factors that may look nothing like today’s pouch, prismatic, or cylindrical cells.See all 7 photosWhat’s the Chemistry?Solid-state battery articles often compare performance with “lithium-ion” chemistry, which always means, generically, the prevailing Li-ion chemistries that employ…
