Polymer‐based separator for all‐solid‐state batteries produced by additive manufacturing

Abstract

The high demand for an efficient energy supply for various applications facilitates the development of innovative storage technologies like all-solid-state batteries in addition to novel production technologies. Compared to the conventional manufacturing process, additive manufacturing (AM) is a promising technology used for the rapid and cost-effective production of battery components containing separators. However, AM technologies like laser-based powder bed fusion of polymers (PBF-LB/P) have been neglected so far. The present research aims to fill this research gap and outline a novel approach for processing polymers like polyethylene oxide (PEO) and polyvinylidene fluoride (PVDF) into separators using PBF-LB/P. Optimal process parameters for manufacturing PVDF and PEO with PBF-LB/P to generate homogeneous and dense layers represent the key findings of this paper and provide a deeper process understanding. The first proof of concept for producing separator layers by PBF-LB/P in a scalable process is demonstrated as a result.

Innovative Approaches to 3D Printing of PA12 Forearm Orthoses: A Comprehensive Analysis of Mechanical Properties and Production Efficiency

“…Most commonly, models made from PA12 material are produced using Multi Jet Fusion (MJF) [39,40] and Selective Laser Sintering (SLS) [41][42][43][44][45] technologies. A vital aspect of the mechanical properties obtained may also relate to how successive print layers are fused.…”
