Sakuu, a provider of commercial-scale equipment to the battery and supercapacitor manufacturing industries, has released performance data on the breakthrough cycle life longevity of battery electrodes produced by the Sakuu Kavian Manufacturing Platform with a fully dry processed cathode.
Kavian enables high-quality, customizable, mass-scale, and cost-effective dry electrode printing, solving foundational challenges confronting mainstream battery manufacturers today.
Test data confirms that a nickel cobalt manganese (NCM) battery cell manufactured on the Sakuu Kavian platform retains 83% charge after 4000 cycles, an unprecedented milestone in battery viability when using a fully dry process to print the cathode, putting it at the forefront of commercially available lithium-ion batteries found in electric vehicles (EVs) and other mass energy storage applications.
For comparison, a typical NCM battery cell should cycle more than 2000 times while retaining at least 80% state of health for minimum EV viability.
The Li-ion battery validation cell producing the dramatic performance is manufactured on Sakuu Kavian without any new materials or optimization:
- 1Ah cell
- Cycled at 1C/1C
- Graphite anode
- Fully dry printed NCM811 cathode
A manufacturing milestone
The dry process enabled by Kavian is a revolutionary innovation that addresses key challenges in scalability, sustainability, safety, and performance, while still reducing cost and enabling manufacturers to regionalize production. Compared to traditional wet-coated electrode manufacturing, Kavian’s dry-process production meets or exceeds standard performance and quality requirements.
The Sakuu Kavian Platform currently dry prints both cathodes and anodes in NCA, NCM, LFP, LTO, graphite, and silicon-graphite chemistries; its flexibility also enables new chemistries, such as aluminum-ion or sodium-ion, and solid-state formulations.
The battery manufacturing benefits of Kavian in terms of sustainability, cost-savings, and efficiency also apply to supercapacitor manufacturing:
- 100% elimination of toxic solvents and water
- 60% smaller footprint of manufacturing floor space
- 30% savings in utility operating costs
- 55% reduction of CO2 emissions
- 20% reduction in capital equipment costs
Sakuu will exhibit at the Advanced Automotive Battery Conference (AABC) in Las Vegas from December 8th to 11th (Booth 611).
