黑石资源一家专注于电池技术的瑞士投资公司宣布，它希望早在2025年就开始商业化新的3D印刷钠离子电池设计。
The firm’s own GermanR&D subsidiary, Blackstone Technology,将与学术和indu的财团strial partners to demonstrate its 3D printed solid-state batteries in a real world use-case within the next three years. Specifically, the 3D printed solid-state batteries will be installed on aEurabus电动巴士，验证他们在道路上的表现。
To fund the commercialization, Blackstone will invest €32 million in a pilot facility at its德国多贝恩的制造工厂。
Blackstone’s consortium partners include theZeiss Group’sMicroscopy and Industrial Metrology arms, which will contribute with expertise in their respective fields. Additionally, the Institute for Particle Technology at theBraunschweig技术大学and three Fraunhofer Institutes –ifam，，，，IKTS，，，，andIST- 将有助于处理过程验证，过程开发，回收和安全。
Moving towards sodium-ion technology
According to Blackstone, modern-day liquid electrolyte battery production lines tend to be very specialized, allowing firms to manufacture only one type of battery at a time. The process is also a very energy-intensive and costly one, and uses dangerous solvents as raw materials for electrodes.
On the other hand, Blackstone’s ‘Thick Layer Technology’ 3D printing approach is intended to be much more flexible and cost-effective, enabling the production of a wider range of cell formats while using environmentally friendly materials. Owing to the versatile nature of the 3D printing process, Blackstone states that it can even tailor the size and shape of the cells to the customer’s requirements.
With the ultimate aim of tackling the electric vehicle market, Blackstone has focused largely on 3D printing lithium-ion batteries until now. The upcoming sodium-ion variants are expected to offer several advantages as the raw materials can be obtained much easier, at lower costs, in a more environmentally-friendly manner.
通过3D打印这些固态电池，黑石声称，与传统制造的同行相比，它可以提高能量密度，同时提高安全性。实际上，该公司认为，第一批钠电池将能够替代各个行业的既定储能系统。
“Sodium-ion technology represents the next generation of our already market-leading 3D printed batteries,” said Holger Gritzka, CEO of Blackstone Technology. “We are pleased to once again make an innovative and viable contribution to clean energy and the carbon-neutral transportation of the future.”
早在2025年就商业化
如果一切都按计划进行，该公司将在2025年底之前在电动巴士中测试其3D印刷钠离子电池电池电池将以各种形状和表演的高速制造 - 全部在一个3D打印设施中。
格里兹卡（Gritzka）补充说：“我们可以无缝地将当前的印刷锂离子电池电极传递到钠离子细胞的生产中。这为2025年随后生产固态钠离子电池的系列生产奠定了基础。”
为了实现这一目标，黑石已经在考虑以吨量表对基于钠的固态电解质进行加工。这项工作是由德国联邦经济和气候保护部资助的，这是其电池电池制造支持计划的一部分。Blackstone预计将从该部获得多达2410万欧元的收入，但要获得批准的赠款。
The 3D printing of energy storage devices is very much a niche field, with much of the work still in its early stages. Last year, researchers at the瑞士联邦材料科学和技术实验室(EMPA) used 3D printing to create a可持续的新类超级电容器。由柔性纤维素和甘油底物组成的完整3D打印电池，用导电碳和含有石墨的墨水组成，能够在保持其容量的同时承受数千个充电周期。
别处，Sakuu Corporation(formerly KeraCel), a specialist in 3D printed energy storage devices, recently reached a new milestone in the development of its lithium metal battery, achieving a benchmark energy density of 800 Wh/L. According to the firm, the achievement is a significant step forwards on its roadmap tofully 3D printed solid-state batteries到2023年，能够大于1200 WH/L。
