Sakuu’s Kavian 3D-printing joins metals, polymers, and binders for cheaper, lighter, more sustainable and power-dense solid-state batteries for future EVs.
San Jose-based 3D-printing startup Sakuu 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, including their inherent fire safety, insusceptibility to freezing, improved energy density, etc.
As for the electrolyte—which is crucial to any lithium-based battery's long-term health and safety—that's still a jealously guarded secret, despite the protection of 80-plus patents. What we do know about what separates the anode and cathode in this 3D printed solid-state battery, is that it was developed at Harvard's John A.
The Kavian platform can print ceramic, glass, metals, and polymer in a single layer—though the company has yet to reveal exactly which materials go into the 3D printed solid state battery. The process is also designed to incorporate artificial-intelligence quality checks of every layer, to minimize defects and scrappage. And the process inherently reduces waste by only applying necessary material and recycling any excess right inside the machine.
An as yet unexplored opportunity is the freedom of form-factor proposed by 3D printed batteries. Last year we explored the. Sakuu's Kavian process for producing Swift Print batteries certainly seems like another potential enabler of this concept, and when the battery's mass is serving a dual purpose that would otherwise be performed by another material, it's no longer a burden to the propulsion system.Perhaps soon, if you're in the market for an electric two-wheeler.
Sakuu's facility in San Jose has also entered limited production of cells for testing and verification purposes and will soon begin shipping these to undisclosed clients in automotive, mobility, aerospace, and industries ranging from IoT devices to medical equipment.
