Blackstone Resources' German subsidiary Blackstone Technology GmbH has successfully printed and tested its first working solid-state battery cell. This marks the successful completion for research and evaluating stage of the 3D screen-printing process, as a new flexible method for producing all kinds of printed solid-state lithium-ion batteries. The following three important proof-of-concepts were achieved:

  • The completion of a 3D printed and mechanically stable solid-state electrolyte as a separator
  • The production of a printable composite cathode (plus the composite of a solid-state electrolyte and lithium iron phosphate)
  • The complete printing process for a 5x5 cm-squared pouch cell as a functioning demonstrator without a mechanical spacer

Blackstone Technology’s 3D-printing and solid-state battery technologies offer substantial advantages over conventional battery cell designs which use liquid electrolytes. It allows significantly lower costs during production, increases the energy density of the cells and offers a higher number of charging cycles. With this step, Blackstone Technology has achieved the highest efficiency and the greatest leverage from its production technology. It represents a gamechanger for the world’s entire cell manufacturing process. It also paves the way for the mass production of solid-state batteries using various cathode materials.

The automotive industry, marine applications and all other applications that require batteries stand to benefit significantly from the advantages that 3D printed solid-state cells can offer. Our 3D printed solid-state batteries are more environment friendly as they are produced in water solvable chemicals, which are also less harmful to the environment and easier to recycle.

Blackstone Technology's is committed to taking the next steps to develop the manufacturing technology needed to bring production to a point where one battery cell is produced every second, with production costs falling to lower than USD65 per kWh. Moreover, the production process offers the potential to save up to 70 % of the traditional Capex and 30 % Opex during the production of these solid-state cells. An additional material saving can be achieved for the electrode chemistry and other used materials.

Blackstone has been investing in the next generation of battery technology through its German subsidiary Blackstone Technology GmbH for many years. This includes patented 3D printing techniques, solid-state technology and the implementation of mass production of batteries in the 3D printing processes.

The first large battery cells developed by Blackstone Technology GmbH have already been presented in February 2021 at the Blackstone Battery day and are ready for the mass production.
