Sakuu’s lithium metal batteries hit milestone of 950 Wh per liter

Sakuu has developed a number of technologies for the commercial-scale production of solid-state and lithium metal batteries. Now the company says it has achieved several important milestones for its lithium metal battery tech.

Samples of Sakuu’s licensable Li-metal Cypress battery cell chemistry, commercially available since May 2023, have been delivered to several customers in the two-wheeled EV space, as well as the e-aviation/drone, defense and power tool industries.

Sakuu says its Cypress Li-Metal chemistry has now demonstrated the following performance specs:

  • 750-950 Wh/l energy density of active cell area
  • 260+ Wh/kg specific energy
  • 792 W/kg specific power (at 3C)
  • 3C sustained discharge, 10C peak, with full recovery
  • 400+ cycles to 80% SOH (100% DoD)

In addition to its Cypress battery cell technology, Sakuu is continuing to make progress on its longer-term initiative known as Kavian, an additive manufacturing platform.

“We have proven with our platform that we can print polymers, ceramics, and metals—using various dry processes in one device and also in one layer—which no other additive manufacturing company can do,” said Arwed Niestroj, Senior VP of Customer Success. “This enables Sakuu to print batteries as well as other active devices.”

“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 CEO and founder Robert Bagheri. “Creating an advanced Cypress battery chemistry uniquely positions Sakuu to deliver on our innovative Kavian manufacturing platform.”
