A rapid increase in accessibility and technical performance of 3D printers has resulted in the adoption and use of 3D printing in a multitude of industries. Given the necessity to develop a new generation of post-lithium-ion batteries, the application of 3D printing for battery design was inevitable. 3D printing can offer several advantages over conventional battery electrodes, electrolytes, and full cell fabrication techniques including introducing additional component functionality, boosting electrochemical performance, improving structural strength, and enabling fine process control and repeatable manufacturability. In this chapter, we start by providing a holistic overview of the motivation for 3D printed batteries. Following, we summarize all the 3D printing techniques used in battery design. We then review key works, categorized by the type of 3D printing technology used. This is followed by a comparison and perspective on the different 3DP techniques in battery design where we highlight the advantages and shortcomings. In particular, we highlight what 3DP technique is best suited for fabricating anode, cathodes, and electrolytes for various common battery chemistries. Lastly, we provide discussion on the major challenges, future trends, and research opportunities for 3D printed batteries.
