New 3D printer can produce batteries on demand
the Sakuu Corporation, a California-based company backed by Musashi Seimitsu, announced a new 3D printing system capable of printing large batteries of electric vehicles on demand. The system uses new techniques to create solid-state batteries which are lighter and smaller than traditional lithium-ion batteries.
The system uses two types of printing to perform the job. It has a powder bed system for sintering the material into solid form and another head for jet deposition which essentially ejects the material to exacting specifications. It prints both ceramic and metal as well as PoraLyte—a medium and a storage medium.
“This is the exact opposite of low energy density SSBs, which typically have thick, brittle ceramic layers and a poor interface, making them unsuitable for high volume production purposes,” Sarah wrote. Saunders to the industry newsletter. 3DPrint.
“Sakuu will initially focus on the market for two, three and smaller electric four-wheeled vehicles for which the company’s SSB proposal offers an obvious and desirable combination of small form factor, low weight and improved capabilities. », Wrote founder Robert Bagheri. in one version. “The agility of Sakuu’s AM process also means that customers can easily switch production to different types and sizes of batteries, if needed, for example, to get double the energy in the same space or the same energy in the same space. half the space. “
Because the whole system is easily changeable, you could print batteries for a car and a scooter on the same day. The company claims its printers are 50% lighter and 20% smaller than traditional LiOn batteries.
Most importantly, however, is the fact that it can use recycled ceramic and metal instead of fresh materials, reducing the battery’s overall environmental footprint. 3D printed batteries are rolling out in limited products including scooters and other electric vehicles.
