Blackstone Technology has confirmed plans for a "tenfold” expansion of manufacturing capacity in Germany for lithium-ion batteries containing 3D-printed electrodes.

A company spokesperson told World Battery News today that its goal of achieving 500 MWh of annual production capacity by 2022, at its plant in Döbeln, could now be confirmed.

The subsidiary of Swiss battery metals investor, Blackstone Resources, also revealed it has signed a letter of intent (LOI) with a major German manufacturer of battery systems for industrial trucks, Triathlon Batterie, to supply 3D-printed battery cells with several 100 MWh annually.

Additional LIOs with customers spanning marine applications, e-motorcycles, e-commercial vehicles and e-buses, are worth a combined sum of around €184m (about £158m), the company said.

Pouch cells

Blackstone has said previously that initial production at Döbeln will be its ‘thick layer technology’ pouch cells, which allows a 20% higher density in lithium-ion cells.
The printing technology allows batteries to be produced in various forms for applications including electric vehicles, electric buses and motorcycles, telecoms networks, tools and drone technology.

The company said it is continuing to further develop its production process and is working on solid-state battery technology.

Earlier this year, Blackstone Resources entered into a convertible loan facility agreement for up to CHF 20m (about £15.5m) to fund plans to mass-produce next-generation 3D-printed solid-state batteries and for other investments.

Meanwhile, Blackstone Resources has appointed Christoph von Aesch as CFO. He most recently held the post of group assurance officer at airline catering firm Gategroup.
