Electric Vehicle Battery Manufacturing with Novel Multi-Material 3D Printer - BattMan 3D

在BattMan3D中，我们将开发创新的新型工业3D打印机，用于制造专为电动汽车设计的电池。通过提高制造技术，我们将支持英国在最先进的电池生产方面建立世界领先的能力。我们的行业专用配方和打印机将设计用于生产具有复杂几何形状的电极，并提高能量密度。我们的工艺将打印整个电池，从阳极到电解液再到阴极，包括外壳。在项目期间，我们将使用典型的锂离子电池化学技术来演示这项技术，但我们的打印机将为未来的电池技术做好准备，能够打印各种阴极和阳极材料以及固态电解质。到项目结束时，我们将开发：*用于电池组件的3D打印机，适用于零售价格低于25万英镑的商业化*可打印配方，利用功能化纳米颗粒，生产电池电极和分离器*演示电池组，与传统生产的电池进行验证和基准测试。这将为电池行业带来重大好处：*替代4步工艺(涂层，干燥，压延，通过简单的沉积和固化，从而将制造时间缩短10倍*将40kWh汽车电池的生产成本降低超过1255英镑*从电池生产过程中去除对环境有害的n -甲基吡咯烷酮（NMP）溶剂*最多可减少85%的废物管理费用通过这种方式，我们将改善电池制造过程中的垂直整合，提高英国的能力和供应弹性。我们还将从制造链中去除高能工艺和高风险材料，同时受益于英国电网的清洁能源结构，以改善汽车电池制造的整体环境足迹。

In BattMan3D we will develop innovative new industrial 3D printers for the manufacture of battery cells designed for electric vehicles. By improving manufacturing techniques, we will support the UK in establishing world-leading capabilities in state-of-the-art battery production. Our industry-specific formulations and printers will be designed to produce electrodes with complex geometries, with improved energy density. Our process will print entire battery cells, from anode through electrolyte to cathode, including the casing. We will demonstrate the technology during the project using typical lithium-ion battery cell chemistry, but our printers will be designed to be ready for future battery technologies, with capabilities to print a range of cathode and anode materials as well as solid-state electrolytes.By the end of the project we will have developed:* A 3D printer for battery cell components, suitable for commercialisation at a retail price below £250k* Printable formulations, utilising functionalised nanoparticles, to produce cell electrodes and separators* Demonstrator battery pack, validated and benchmarked against conventionally produced batteriesThis will have significant benefits for the battery industry:* Replacement of a 4-step process (coating, drying, calendaring, notching) with simple deposition and cure, thus reducing the fabrication time by a factor of 10* Reduction of production costs for a 40kWh auto battery by more than £1255* Removal of environmentally damaging N-methyl pyrrolidone (NMP) solvents from cell production process* Up to 85% reduction in waste management expenseIn this way we will improve vertical integration in the cell manufacture process, improving UK capabilities and resilience of supply. We will also remove high-energy processes and high-risk materials from the manufacturing chain, while benefiting from the cleaner energy mix of the UK grid to improve the overall environmental footprint of automotive battery manufacture.
