Sakuu Corporation Begins Work on New Pilot Plant for 3D Printed Solid State Batteries


Applications for the 3D Printing Industry Awards 2021 are now open. Who do you think should be on this year’s show shortlists? Give your opinion now.

Sakuu Company (formerly KeraCel), a specialist in 3D printed energy storage devices, has started construction of a new pilot plant for the production of 3D printed solid-state batteries.

Scheduled to be completed by the end of 2021, the pilot line would be capable of producing up to 2.5 MWh of solid state batteries each year. In the coming years, it will also serve as a customer learning center for the company’s multi-material 3D printing system, the “Sakuu AM Platform”. Engineering firms Relevant industrialist and Honeywell assist with the setup of the facility by providing engineering, process design and systems integration support.

John Carte, CEO of Relevant Industrial, said: “Relevant is delighted to be part of this revolutionary project. The combination of state-of-the-art technology from Sakuú and our experience in engineering, design and system integration using Honeywell’s advanced automation technologies provides a unique opportunity to shape the future of the industry. manufacturing. We appreciate Sakuú’s confidence in Relevant and look forward to a long and mutually beneficial partnership.

Towards 3D printed solid-state batteries with Sakuu

Since KeraCel’s rebranding earlier this year, Sakuu has focused on 3D printing solid-state batteries for applications such as electric vehicles. The company’s newly developed Sakuu AM platform combines powder bed technologies with material jetting and is compatible with the company’s ceramics, metals, and “Poralyte” carrier material. According to the company, the 3D printing technology is capable of producing solid state batteries with half the size and double the capacity of traditional lithium-ion cells, while being “much less” expensive to buy. high volumes.

Sakuu also recently obtained three new patents, each of which aims to improve the efficiency and flexibility of the company’s multi-material additive manufacturing capabilities.

Solid-state battery pilot installation

The next pilot line is expected to demonstrate the viability of Sakuu’s battery production process while allowing the company to provide battery samples to its Early Access partners. Relevant and Honeywell will help evolve technology historically based on Sakuu’s lab into a full-fledged manufacturing facility.

In 2022, the project will then move into its second phase, where a fleet of Sakuu AM platforms will be used to 3D print solid-state batteries totaling up to 1 GWh of capacity per year.

Robert Bagheri, CEO and Founder of Sakuu Corporation, adds: “This is an important milestone for Sakuú. The development of our SSB technology progressed to the point where we decided to go ahead with our plan to build and operate a pilot plant. With the help of our key development partners, Relevant Industrial and Honeywell Process Solutions, the facility will be operational by the end of 2021. This facility will allow us to provide our strategic customers and partners with rapid access to batteries. semiconductors for their own development and testing. “

3D printing of energy storage devices is still a niche field. Earlier this summer, the Swiss mining and investment company Blackstone Resources announced that it is considering listing its Blackstone Technology division on the US stock exchange. While details of its subsidiary’s operations are scarce, the company says it is developing 3D printing technology capable of producing high energy density lithium-ion batteries.

Elsewhere, in the academic world, researchers from California Institute of Technology (Caltech) recently developed a new method of 3D printing electrodes for lithium-ion batteries. Using DLP 3D printing technology, a form of visible light-based cuvette curing, researchers were able to fabricate complex polymer structures before converting them into useful electrode materials via a heat post-treatment treatment.
