Abstract Scope |
The development of solid-state energy storage devices is crucial for customized electronics and modern technologies. This study shows fabricating lithium-ion (Li-ion) battery cells using direct ink writing (DIW) for precise 3D printing. The cathode material in this work is lithium iron phosphate (LiFePO₄) mixed with carbon black (CB), and the anode is lithium titanate (Li₄Ti₅O₁₂) mixed with CB. A solution of lithium hexafluorophosphate (LiPF₆) is used as electrolyte in this experiment. With meticulously formed electrodes, the fully printed battery demonstrated significant mechanical deformability and a high discharge capacity of roughly 104 mAh g⁻¹. By using this integrated 3D printing technique, battery cells with extended surface area and customizable shapes can be produced, which increases flexibility and performance. Overall, this work focuses on the potential of DIW based manufacturing in creating flexible Li-ion batteries and lays the groundwork for creative designs in upcoming energy storage devices. |
