Abstract

The growing demand for advanced energy storage systems has increased the need for lithium-ion batteries with improved performance, design flexibility, and efficient manufacturing processes. Conventional lithium-ion battery electrodes are commonly produced through slurry coating and drying methods, which can limit geometric control, increase processing time, and restrict the development of customized electrode structures. Direct Ink Writing (DIW), an extrusion-based 3D printing technique, offers a promising approach for fabricating battery electrodes with controlled material deposition and tunable architecture. This thesis focuses on the development of printable composite anodes for lithium-ion batteries using lithium titanate, carbon black, styrene-butadiene-styrene binder, and toluene-based ink formulations. The prepared inks were evaluated to identify a suitable balance between flowability, structural recovery, and printability. The optimized ink formulation was printed onto copper foil substrates and characterized using rheological, morphological, structural, surface chemical, and electrochemical analyses. The results demonstrate that DIW can successfully fabricate LTO-based composite anodes with stable morphology and long-term electrochemical functionality. This study supports the potential of DIW printing as an alternative electrode fabrication method and provides a foundation for future development of customizable and high-performance lithium-ion battery electrodes.
