Electric vehicles and most electronic devices, such as smartphones and laptop computers, are powered by lithium-ion batteries. Until now, manufacturers have had to design their devices around the size and shape of commercially available batteries. But researchers have developed a new method to 3D print lithium-ion batteries in virtually any shape. They report their results in ACS Applied Energy Materials . Most lithium-ion batteries on the market come in cylindrical or rectangular shapes. Therefore, when a manufacturer is designing a product — such as a cell phone — they must dedicate a certain size and shape to the battery, which could waste space and limit design options. Theoretically, 3D-printing technologies can fabricate an entire device, including the battery and structural and electronic components, in almost any shape. However, the polymers used for […]
