Sakuu has introduced that its Kavian additive manufacturing platform can dry-print lithium-ion battery cathodes with main cycle life utilizing current high-nickel chemistry. The corporate claims that cells manufactured through Kavian’s absolutely dry course of retained 83 p.c of their authentic cost capability after 4,000 cycles, surpassing typical requirements for EV batteries.
In response to Sakuu, the examined battery cell used a 1 Ah configuration, graphite anode and a completely dry-printed NCM811 (nickel cobalt manganese) cathode. The cell underwent biking at 1 C cost and 1 C discharge charges. The corporate compares this longevity favorably to business benchmarks, which require commonplace NCM cells to surpass 2,000 cycles with at the least 80 p.c capability retention for minimal EV software viability.
Sakuu says the Kavian platform permits the dry printing of each anodes and cathodes with conventional chemistries, akin to nickel-cobalt-aluminum, lithium-iron-phosphate, lithium-titanate, graphite and silicon-graphite. It could actually additionally adapt to new chemistries like aluminum-ion, sodium-ion and solid-state battery supplies.
Kavian can be able to dry printing supercapacitor electrodes, addressing rising energy administration wants in purposes akin to AI information facilities. The platform’s course of eliminates hazardous solvents and water, lowering manufacturing flooring house by 60 p.c, reducing working prices by 30 p.c, slicing carbon dioxide emissions by 55 p.c, and lowering capital tools prices by 20 p.c.
The corporate experiences that it has already provided tons of of meters of dry electrode materials to clients and is working to meet preliminary orders for the Kavian system.
“Our in depth testing confirms that Kavian’s dry manufacturing course of might be reliably trusted to ship a product that can meet or exceed the capabilities of present moist processes,” mentioned Robert Bagheri, Sakuu founder and CEO. “This once more dispels any doubts as to the suitability of utilizing a dry course of for printing lithium-ion battery electrodes.”
