Researchers Publish Summary of 3D Printing in Electrochemical Energy Storage Methods

3D printing is advancing the field of electrochemical energy storage devices (EESD). The technology’s flexibility, design freedom, cost-effectiveness, and eco-friendliness make it suitable for developing batteries and supercapacitors across scales. These 3D printed devices demonstrate enhanced ion/electron transport and kinetics, resulting in superior energy density and rate capability.

Prof. Lin Zeng from the Southern University of Science and Technology in China has spotlighted the advancements in 3D printing for rechargeable batteries. Their review in the International Journal of Extreme Manufacturing sheds light on major 3D printing methods, design tenets, material selection, and optimization techniques for EESD. Importantly, they delve into essential materials like the anode and cathode electrodes, electrolytes, membranes, and 3D current collectors.

In addition to highlighting the various processes for 3D printing batteries, the paper examines the challenges in 3D printing for EESD. Enhancing 3D printing equipment, exploring multifunctional additives, and understanding the interplay between electrochemical performance and structural design are vital for optimizing battery functionality.

“To advance the commercial applications, some factors need to be considered for practical production, such as manufacturing cost, uniformity of product (including structural stabilities and performance stabilities), and potential application scenario and market sizes,” said Lin.

“Among many factors, the costs of 3D printed equipment and printable materials are the key to commercial application; factors such as premises and staff cannot be ignored. The safety performance of the final products for power batteries should be significantly improved to show attractive technical advantages and commercial values, especially under high energy densities and reduced manufacturing cost.”

As the 3D printing domain expands in electrochemical energy storage, researchers will likely focus on refining the technology, addressing challenges, and unlocking further capabilities for next-generation EESD applications.
