3D printing for all-solid-state batteries

3D printing technology has garnered significant attention due to its capability for precise fabrication of complex battery structures, as well as its advantages of low cost and environmental sustainability. By integrating computer-aided design (CAD) with advanced manufacturing processes, 3D printing enables rapid prototyping, accelerated design, testing, and iteration of novel battery structures. Consequently, a growing number of researchers are exploring the use of 3D printing technology for the production of all-solid-state batteries (ASSBs), presenting new possibilities for breakthroughs in future energy storage technologies. In this review, we discuss the differences between traditional battery manufacturing methods and the application of 3D printing techniques for ASSBs fabrication. The working principles, advantages, and limitations of various 3D printing technologies in solid-state battery production are specifically highlighted, along with the challenges that can be addressed by 3D printing. The perspectives on the future development of 3D printing technology in battery manufacturing are proposed.
