US battery technology developer Sakuu is launching a high power density lithium metal battery cell chemistry for licensing to manufacturers.

The Cypress cell supports  8C pulse discharge and 3C continuous discharge and an energy density of  750+ Wh/l, close to the target values for lithium metal cells.

Industry-standard certification procedures are underway, including UN/UL testing. Samples of a 5Ah pouch cells are available from Sakuu’s Silicon Valley battery pilot line facility. This is a traditional manufacturing process before Sakuu rolls out its 3D printed batteries.

“Our proprietary lithium-metal battery chemistry delivers key cell performance and safety attributes that enable a new paradigm in battery manufacturing and energy storage,” said Sakuu Founder and CEO Robert Bagheri. “We are pleased to launch our Cypress cell chemistry for licensing to today’s battery manufacturers, using roll-to-roll manufacturing technology. We at Sakuu are excited to enable the acceleration of electrification for mobility and other markets.”

“Lithium-metal battery chemistries produce increased energy density and additional performance benefits, but typically present development challenges due to high reactivity,” said Sakuu Senior Vice President Arwed Niestroj.

“With Cypress, Sakuu has solved these issues through novel electrochemistry, making lithium-metal chemistry ready for scalable production. 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. Manufacturers can now license this technology.
