Swiss firm Blackstone Assets AG (SWX; image BLS, ISIN CH0460027110, WKN 460027110) has introduced that it has demonstrated its battery 3D printing know-how earlier than the press and is opening its first manufacturing plant earlier than the top of the 12 months.
On the occasion, the corporate was mentioned to have offered its 3D printed lithium-ion phosphate (LFP) battery cells made utilizing materials from IBU-Tec. The corporate claims to have begun manufacturing on its LFP cells in Döbeln in Germany utilizing Blackstone Thick Layer Expertise. The cell is ready to obtain 220 Wh/kg, in comparison with a historically made cell that achieves 166 Wh/kg.

Blackstone says that it is usually starting to fabricate nickel-manganese-cobalt (NMC) cells, however that it goals to supply solid-state batteries sooner or later, believing that it will possibly enhance power density by 70 %. In the meantime, Sakuu, within the U.S., claims to already be 3D printing stable state batteries.
CEO Ulrich Ernst mentioned, “In entrance of an assembled press and numerous viewers within the on-line stream, we’ve got now demonstrated: our patented 3D printing know-how for the manufacturing of climate-friendly, sustainable and significantly highly effective lithium battery cells is prepared for collection manufacturing!”
Whereas there was a url shared for the present, it was tough to search out any press protection of the occasion itself, which Blackstone claims was meant to be stay however was rescheduled as an internet presentation because of the pandemic. Due to this fact, it’s tough to validate if there actually was an assembled press there to witness what is supposed to be a virtually unprecedented know-how.
Nevertheless, the agency notes that quite a few individuals offered on the occasion, together with Robert Orten, CEO of Orten Electrical Vans; Thomas Sautter, of Voith SE & Co KG; Benjamin Friedrich, of ecolvolta AG; Dr Michael Roscher, of LioVolt; and Dr Axel Fuerst of the Bern College of Utilized Sciences (BFH). Video protection about (not of) the occasion is embedded under, with the YouTube caption: “Loads of press representatives got here to the massive press convention of Blackstone – amongst them additionally the ZDF. The reporters had been capable of persuade themselves on website of our innovation: 3D-printed lithium batteries for a sustainable and environmentally appropriate transport turnaround!”
In line with Blackstone, the 3D printing system is able to producing thicker “energy-storing layers within the battery cells, which will increase the gravimetric power density by a powerful 20 %.” The dimensions can be tailored to buyer wants, whereas the battery itself is described as 15 % smaller than conventional batteries. Materials saving is described as 20 euros/kWh and power utilization throughout manufacturing is alleged to be lower by 23 per cent.
“On the similar time, the method depends on an environmentally pleasant, purely water-based course of and reduces waste supplies by 50 per cent. On this method, we’re making an essential and sustainable contribution to the transport transition and within the combat in opposition to local weather change,” mentioned Ernst.
Given the truth that our trade is full of hype and unbelievable applied sciences, it’s tough to validate the work of Blackstone or Sakuu. That is significantly essential when an organization like Blackstone is publicly traded and concerned in mining, an trade fraught with fraud, as I’ve mentioned beforehand.
We’ve reached out to Dr Axel Fuerst of BFH to verify his participation within the occasion. Nevertheless, BFH did publish a put up validating the know-how, stating (Google translated from German), “Researchers on the Institute for Clever Industrial Methods I3S at Bern College of Utilized Sciences BFH have now fastidiously examined the manufacturing course of for this battery. In a fancy simulation, they had been capable of present that the 3D printing course of patented by Blackstone really reduces materials prices by round 20 euros / kWh – primarily thanks to raised utilization of so-called inactive supplies akin to separators and collector foils. Though these don’t contribute to power storage, they’re nonetheless needed in a battery.”

The corporate claims to be partnering with Orten Electrical Vans, a division of a longtime truck and trailer physique producer devoted to electrifying vans. Along with Voith SE, a longtime Swedish producer based in 1867, the three companies goal to impress e-buses with Blackstone know-how. Blackstone additionally says that it might associate with an organization known as LioVolt, established solely this 12 months, to supply a bipolar lithium-ion battery.
Given the names concerned, together with Orten, Voith, and BFH, it will appear as if Blackstone is sincere about its know-how to the extent that it has companions on board and a college validating its existence. So, we could hedge our bets on the aspect of Blackstone being as on the extent as another startup within the area. With that in thoughts, we are able to assume that Blackstone’s Döbeln plant actually will make use of 38 individuals by the top of 2021, as the corporate states.
