Eli Kindomba is a Mechanical Engineering graduate student interested in sustainable energy, additive
manufacturing, bioengineering and space power architectures. He is conducting his thesis research on
lithium-ion batteries fabrication via additive manufacturing. Eli has a Bachelor of science in Mechanical
Engineering from Indiana University Purdue University Indianapolis. He served as the President of the
IUPUI Chapter of the Students for the Exploration and Development of Space (SEDS).
In this work, 3D printing of lithium-ion battery (LIB) components using the fused deposition modeling (FDM) process is presented. The filament’s formulation, printability and material properties are characterized. Specifically, the graphite/polylactic acid (PLA) filaments are modified from a recipe in literature. In our LIB designs, the graphite/PLA serves as the anode, and high-performance cathode filament is explored as well. These filaments are studied and compared based on their printability, electrochemical performance, and mechanical characteristics. Through this study, printed electrodes and separator materials can be assembled to form a fully 3D printed battery of complex desired shapes with optimized energy density and sufficient mechanical strength.
