This study examines how stresses in polymer melts affect fiber void space and cross-sectional shapes during 4-C segmented arc melt spinning, a process where polymer extruded through four C-shaped arcs coalesce after extrusion to form a single hollow fiber. We conducted spinning trials under various conditions and analyzed hollow fiber cross sections by measuring circularity and hollowness, defined as the volume fraction of the fiber’s hollow core relative to the total fiber volume. Rheological properties of different polypropylene melts at the temperature and conditions of spinning are related to the final fiber properties to show that the processing parameters of spinning temperature and flow rate are of significance. Experiments maintaining constant denier, or linear density, reveal that hollowness and circularity are related to the flow behavior through the Weissenberg number (Wi). At low Wi, hollowness increases with Wi; however, as Wi exceeds unity, the polymer takes on more elastic characteristics and the fiber transitions to constant hollowness, followed by instability at higher Wi values. Computational fluid dynamics (CFD) simulations using the Giesekus model allow for the analysis of stresses present during extrusion, revealing that uneven stress distributions at high Wi lead to a decrease in the circularity of the inside of the fiber. At low Wi, the extruded polymer melt has more viscous character and more time to resolve stresses in the melt before solidification, creating a fiber that retains less hollowness but more shape uniformity. A generalized inverse relationship between fiber circularity and hollowness is also observed across various polymer samples, flow rates, and temperatures.

Lithium-ion batteries (LIBs) are currently the most advanced and widely used technology in this field. Traditionally, LIBs are manufactured using simple 2D planar geometries to maximize production efficiency and minimize costs. However, this approach limits energy density due to the restricted design flexibility of the electrodes. Additive manufacturing (AM) offers a promising solution to enhance the energy density and efficiency of LIBs by enabling the design of architectures that reduce diffusive losses and allow for a greater amount of active material to be incorporated within the same device footprint, thereby minimizing the use of inactive materials. Different AM techniques come with their own set of limitations, including printing speed, material compatibility, and scale, which must be considered when designing electrodes. Scalable and cost-effective methods are particularly important for electric vehicle batteries, while achieving higher energy densities in microbatteries is crucial for the miniaturization of wearable electronics and medical devices. In this study, we simulate various 3D porous electrode designs for LIBs using graphite and nickel manganese cobalt oxide (NMC) electrodes. These designs are selected to represent structures that could be produced using different AM techniques, such as direct ink writing, fused deposition modeling, and stereolithography. Our results indicate that at higher charging rates and increased areal mass loading, 3D structures can outperform traditional 2D electrodes, although the benefits may diminish with more complex designs that are harder to manufacture. The observed gains in energy density are attributed to improved electrode utilization and reduced diffusive energy losses.
