Sakuu’s dry-printed UN38.3 certified li-metal batteries hit 1,000-cycle milestone

May 13, 2024

Sakuu has announced it has hit the 1,000-cycle milestone of its Li-Metal Cypress cell using a fully dry manufacturing process.

The company reports it has successfully addressed the known challenges of Li-Metal anode chemistries in both wet and dry electrode manufacturing. This is demonstrated in its commercial-grade battery cells, which currently deliver:

– 1,000 cycles at 100% DoD to 80% SOH @ 0.3C/1C– 800+ Wh/l Energy Density of active cell area– 3C Sustained Discharge, 10C Peak, with full recovery– 8C Pulse Discharge

The Cypress battery cell has also recently achieved UN38.3 certification.

The company says its Kavian platform, used for manufacturing Cypress in a fully dry process, offers several benefits. It eliminates all toxic solvents and materials, including NMP and PTFEs, reduces factory floor space requirements by up to 33%, cuts utility costs by up to 40%, and improves factory carbon footprints by up to 40%.

Sakuu’s dry-process platforms enable rapid innovation while reducing waste and avoiding toxins.

Robert Bagheri, CEO and Founder of Sakuu, said, “The biggest challenge in battery manufacturing today is producing next generation batteries cost-effectively at scale to meet demand. Manufacturing Cypress in a fully dry process with the Kavian platform is a key step in enabling high-quality solid-state batteries to be produced in high volume in the future. Leveraging dry printing will enable battery technology innovation to accelerate the adoption of EV’s while eliminating range anxiety.”
