Blackstone Technology GmbH produces climate-friendly and clean batteries for a sustainable change in traffic and transportation. With 3D-printed batteries, a world first in the manufacturing segment, we have now made the quantum leap: A significantly increased energy density of +20% promises more range in electromobility, and in production the consumption of critical raw materials and chemicals is sustainably avoided or reduced. In addition, the manufacturing costs of 3D printing are significantly lower compared to currently widespread production processes for lithium-ion batteries.
