3D Li-Ion Batteries Through Advanced Manufacturing

Increasing demands in storage systems for enhanced energy and power are driving innovative research in the design of better material systems and devices. Li-ion batteries are the leading technology and major power source for portable electronics; however, they fail to meet the demands for sustainable energy applications, such as electric vehicles and storage for renewable energy. 3D batteries have potential to maximize energy and power densities through nanoarchitecture, reducing ionic and electronic diffusion lengths. We focused on developing an advanced manufacturing process that is capable of fabricating 3D Li-ion electrodes to maximize volumetric energy and power densities while maintaining mechanical strength. Electrode materials were characterized via scanning electron microscopy and X-ray diffractometry. With the implementation of new technologies for this project, we learned about the support and processes required to enable effective R&D. This includes the contributions and requirements of work controls, procurement support, safety evaluation, laboratory training requirements, and project management.
