Sakuu Corporation, founded in 2016 in Silicon Valley, California, specializes in advanced battery manufacturing technologies. The company has developed innovative solutions for producing lithium metal batteries using additive manufacturing, specifically through 3D printing processes. Sakuu’s mission focuses on creating sustainable manufacturing methods for next-generation batteries while reducing dependency on traditional energy sources.
The company’s primary innovation lies in its ability to produce custom-shaped batteries with enhanced thermal management capabilities. This approach represents a significant advancement in battery manufacturing, offering improved performance metrics and environmental benefits compared to conventional production methods.
Battery Technology
At the core of Sakuu’s technological offerings is the Kavian platform, which enables commercial-scale production of batteries through a unique dry, multi-material, multi-layer approach. This platform allows for the creation of batteries in various shapes and sizes, incorporating patterned openings for thermal management without requiring solvents.
The company’s Cypress battery cell chemistry demonstrates exceptional performance characteristics, achieving energy densities of 750–950 Wh/l and specific energies exceeding 260 Wh/kg. These batteries deliver 8C peak power output, 10C pulse capabilities, and 3C continuous discharge rates. Additionally, they maintain operational effectiveness for 1000 cycles from 100% depth of discharge to 80% state of health.
Sakuu’s manufacturing process significantly reduces material waste and eliminates toxic components through its dry process methodology. This approach aligns with environmental sustainability goals while maintaining high performance standards. The company’s technology portfolio includes the first fully functional printed lithium-metal battery and the first printed and patterned lithium-metal anode.
Recent Projects
In January 2025, Sakuu made its Kavian Platform commercially available, marking a significant milestone in sustainable battery manufacturing. The platform demonstrates a 55% reduction in CO2 emissions during electrode production compared to traditional methods.
The company formed strategic partnerships with ELEQTRION for aluminum-ion battery development and SK On for enhancing electric vehicle battery manufacturing. These collaborations aim to advance sustainable energy storage solutions. Additionally, Sakuu received recognition as an FII Innovator 2024 and earned a place in TIME’s Best Inventions of 2024.
Investors
Sakuu has secured $115 million in funding from various investors, including Candou Ventures, Teramips Technologies, CSVE Ventures, Plug and Play, and MissionBlue Capital Partners. The company has also established strategic partnerships with industrial leaders like Honeywell and Relevant Industries for specific development projects.
The company plans to become publicly traded through a merger with Plum Acquisition Corp. I, representing a significant step in its expansion strategy.
