Sakuu, the California-based battery production technology developer, said it has achieved several milestones connected to manufacturing of the next generation of batteries. Sakuu has made a reputation for its 3D printed solid-state batteries for licensing, and now fast progress has been made concerning lithium metal chemistry for increased cell performance, it said.
The newest applications of the company’s Cypress battery chemistry are designed to fit the roll-to-roll battery manufacturing process, which is expected to become common for batteries intended for high-power use, e.g. drones, e-aviation, power tool and the defence industries.
Sakuu claims to have achieved the new level of 950 Wh per litre of active area in its lithium pouch cell. It said the anode cell delivering cycle exceeds 400 (1C @ 25oC) to 80% discharge capacity. Sakuu’s new Li-Metal anode with high nickel cathode should deliver 10C peak discharge with full recovery.
“We are in the business of developing and licensing revolutionary manufacturing technology for OEMs to mass produce batteries with higher performance at less cost,” said Robert Bagheri, CEO and Founder of Sakuu.
Sakuu operates two plants in Silicon Valley, one for pouch cells, one for battery production additives. The company has also revealed plans for 200 GWh output capacity of lithium metal and solid-state batteries by 2030, designed in cooperation with Porsche Consulting.
The company has developed the Kavian platform to produce 3D-printed solid-state batteries. The process can be applied to both ceramic and metal materials and to a carrier material, PoraLyte, developed by Sakuu. The new material is said to enable solid and fast printing of 3D components without brittle ceramic layers.
Robert Bagheri, founder and CEO of Sakuu said: “The compatibility with 3D-printing will further enhance the effective use of battery packaging volume with new and unique approaches to thermal management. Li-Metal cells have advantages that Sakuu has made attainable, scalable, and safe.”
