Sakuu, a supplier of commercial-scale gear to the battery and supercapacitor manufacturing industries, has launched efficiency information on the breakthrough cycle life longevity of battery electrodes produced by the Sakuu Kavian Manufacturing Platform with a completely dry-processed cathode. Kavian permits high-quality, customizable, mass-scale, and cost-effective dry electrode printing – supplying advantages that clear up foundational challenges confronting mainstream battery producers right this moment.
Check information confirms {that a} nickel cobalt manganese (NCM) battery cell manufactured on the Sakuu Kavian platform retains 83% cost after 4000 cycles, an unprecedented milestone in battery viability when utilizing a completely dry course of to print the cathode, placing it on the forefront of commercially obtainable lithium-ion batteries present in electrical autos and different mass power storage purposes. (For comparability, a typical NCM battery cell ought to cycle greater than 2000 instances whereas retaining a minimum of 80% state of well being for minimal EV viability.)
“We’re so pleased with the efficiency of Kavian-manufactured battery electrodes,” mentioned Robert Bagheri, Sakuu Founder, CEO, and Government Chairman. “Our in depth testing confirms that Kavian’s dry manufacturing course of will be reliably trusted to ship a product that can meet or exceed the capabilities of present moist processes. This once more dispels any doubts as to the suitability of utilizing a dry course of for printing lithium-ion (Li-ion) battery electrodes. This myth-busting achievement is a testomony to our supplies engineering experience, as prospects inform us different additive producers experimenting with dry processes wrestle to realize passable outcomes throughout all the printed electrode – notably the cathode.”
The Li-ion battery validation cell producing the dramatic efficiency is manufactured on Sakuu Kavian with none new supplies or optimization, together with: 1Ah cell; cycled at 1C/1C; graphite anode; and absolutely dry printed NCM811 cathode.
The dry course of enabled by Kavian is a revolutionary innovation that addresses key challenges in scalability, sustainability, security, and efficiency, whereas nonetheless decreasing value and enabling producers to regionalize manufacturing. In comparison with conventional wet-coated electrode manufacturing, Kavian’s dry-process manufacturing meets or exceeds customary efficiency and high quality necessities.
The Sakuu Kavian Platform at present dry prints each cathodes and anodes in NCA, NCM, LFP, LTO, graphite, and silicon-graphite chemistries; its flexibility additionally permits new chemistries, comparable to aluminum-ion or sodium-ion, and solid-state formulations.
Kavian will not be solely one of many world’s first additive manufacturing options to dry print battery electrodes; it additionally dry prints supercapacitor electrodes to fulfill the distinctive energy wants of AI information facilities, the place demand is surging. Furthermore, the battery manufacturing advantages of Kavian by way of sustainability, cost-savings, and effectivity additionally apply to supercapacitor manufacturing, together with: 100% elimination of poisonous solvents and water; 60% smaller footprint of producing flooring area; 30% financial savings in utility working prices; 55% discount of CO2 emissions; and 20% discount in capital gear prices.
The Sakuu workforce is engaged on fulfilling the primary orders for Kavian and has already delivered lots of of meters of high-quality dry electrode to prospects.
