3D Printing of Solid State Batteries with Controlled Geometry

这个项目旨在开发3D打印电池，使用PhotoCenter的新型3D打印工艺，其中液晶(LCD)屏幕发出的可见光被用来选择性地固化精度低于10微米的液体光聚合物。21世纪的一大挑战是电化学储能，从而生产出更高效的电池。尽管在这一领域取得了进展，特别是在锂离子电池的开发和可靠性方面，但主要的挑战仍然是获得高能量密度和功率密度、重量轻、安全和性价比高的电池。提高电池性能的主要障碍是目前的制造工艺包括多个耗能和劳动密集型步骤，几乎没有定制的空间，如改变几何形状。该可行性项目的目的是使用最先进的3D打印来设计和制造各种电池部件的电池材料以及尺寸精确控制的电动汽车固态电池，我们打算与工艺创新中心(CPI)和强生马泰(JM)合作，开发可3D打印的单边带材料，并采用我们的3D打印方法来快速高效地制造电池。这项技术将在小规模电池上进行测试，作为一种验证概念，并随后扩大规模。

"This project aims to develop 3D printed batteries using Photocentric's novel 3D printing process, in which visible light emitted from liquid crystal (LCD) screens, is being used to selectively cure liquid photopolymer with a sub 10-micron accuracy. A major challenge of the 21st century is electrochemical energy storage, thus the production of more efficient batteries. Despite the progress achieved in this field, especially on the development and reliability of lithium-ion batteries, the main challenge remains to obtain batteries with high energy and power density, lightweight, safe and cost effective.The main hurdle for achieving improved battery performance is the current fabrication process include multiple, energy and labour-intensive steps, which has little scope for customisation such as changing geometry.The aim of this feasibility project is to use state-of-the art 3D printing to design and manufacture of battery materials for a variety of battery parts as well as solid state batteries for electric vehicles with accurate control of size, shape and porosity of electrodes to enable high energy density while minimising the overall size and weight.In collaboration with the Centre for Process Innovation (CPI) and Johnson Matthey (JM), we intend to develop 3D printable SSB materials and adapt our 3D printing method for fast and efficient fabrication of batteries. This technology will be tested on small-scale batteries as a proof concept and subsequently scaled up."
