Scientists Eye 3D Printing for Next-Gen Flexible Batteries

3D printing has proven to be the perfect ally for a myriad of technologies. We’re increasingly witnessing a growing trend of 3D printing expanding into diverse fields with remarkable outcomes. Recent breakthroughs, such as the proposal by a team of researchers from various Chinese universities to 3D print flexible batteries, exemplify this trend. Their scientific article sets the stage for future advancements in manufacturing, particularly in the realm of flexible electronics.

Since the inception of flexible batteries, the proliferation of wearable electronic devices has surged. From watches to foldable smartphones, smart clothing, and even medical implants, these batteries have found diverse applications. Their unique ability to bend and stretch without compromising functionality makes them ideal for devices with varied designs, seamlessly conforming to the contours of the human body. Just as flexible batteries have changed the technological landscape, so has 3D printing. Today, we’ll explore a groundbreaking collaboration among researchers from various universities in China, pioneering the fusion of additive manufacturing of flexible batteries.

Not So Flexible, Flexible Batteries

The conventional approach to manufacturing flexible batteries, known as “sludge coating,” involves combining cathodes, anodes, and electrolytes, which are the primary components of batteries. While effective, researchers note that this method falls short, leaving much to be desired in terms of customizing the battery’s architecture, configuration, and appearance.
