Forbes reports on a brand new study just recently published by Carnegie Mellon University’s College of Engineering. Apparently, these researchers “have come up with a new method of fabricating batter electrodes using Aerosol Jet 3D printing. The Aerosol Jet system also allows the researchers to print planar sensors and other electronics on a micro-scale.”
As the researchers explain: “currently, the electrode materials of lithium-ion batteries are mixed with a glue-like substance called binders which are pressed onto electrodes and physically kept apart by a polymer separator. These pressed electrodes have a block geometry which means that 30 to 50% of the electrode isn’t utilized, reducing capacity.”
Now, “due to lower weight and higher capacity of the 3D printed batteries, they can be used more efficiently in small drones, smartphones, medical devices, and aerospace industries, as well as biomedical electronic devices.” This will all be due to the high demand for miniaturized batteries.
Thanks to this new method developed by the researchers at Carnegie Mellon, “it will now be possible to 3D print the battery electrodes by assembling individual droplets one-by-one into three-dimensional structures. The stress in the 3D printed electrodes is now distributed uniformly versus traditional methods of uneven distribution in block electrodes.”
This is great news for the average consumer because “this new method of 3D printing these micro-lattice batteries can reduce charging times and increase capacity” within the batteries.
