Solid-state battery pioneer Sakuu has launched a new Li-metal cell chemistry called Cypress. The new technology, which Sakuu says delivers safer batteries with high energy and power densities, is now available for manufacturing licensing.
“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.”
Sakuu says Cypress offers energy density of 750+ Wh/l, and high power: 8C pulse discharge, 3C continuous discharge.
Industry-standard certification procedures are underway, including UN/UL testing. Samples of 5 Ah pouch cells are available from Sakuu’s Silicon Valley battery pilot line facility.
“Lithium-metal battery chemistries produce increased energy density and additional performance benefits, but typically present development challenges due to high reactivity,” said Sakuu Senior VP 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.”
