3D printing Lithium-ion batteries
Three-dimensional (3D) printing technology has demonstrated great potential in fabricating flexible and customizable high-performance batteries, which are highly desired in the forthcoming intelligent and ubiquitous energy era. However, a significant performance gap. Here, for the first time, we developed a series of thermoplastic polyurethane (TPU)–based 3D-printed electrodes via fused deposition modeling for flexible and customizable high-performance lithium-ion batteries. The electrodes are well-printed with high dimensional accuracy, flexibility, and mechanical stability. Our findings provide a new avenue to achieve customizable and flexible batteries and guide a promising way to erase the performance gap between 3D-printed and conventional lithium-ion batteries.
Additionally, a vital aspect in advancing flexible batteries is the development of flexible electrodes capable of enduring repeated stretching while upholding satisfactory electrochemical performance. Thus, adopting a systematic and efficient approach to structural design and fabrication becomes imperative. In this study, we introduce an optimal structural design achieved through topology optimization and fabricating flexible electrodes via 3D printing, representing a departure from traditional design and manufacturing methodologies in the development of flexible electrodes for batteries. These findings highlight the significant potential of topologically designed flexible electrodes, offering promising avenues for developing stretchable and flexible energy storage devices such as wearable tech and bio-integrated electronics.
