Researchers create micro-battery with 3D printer (video)
We frequently hear concerning the coming nanobot revolution, however simply how are scientists planning on powering these future marvels? Nicely, researchers from Harvard and the College of Illinois might have discovered the answer in a 3D-printed battery: it is smaller than a grain of sand, but has areal power and energy densities similar to your cellphone battery. The staff used a customized 3D printer with a 1mm broad nozzle to deposit two separate lithium metallic oxide pastes into comb-like shapes, which then hardened to create an anode and cathode. After including an electrolyte, a sub-hair-width cell was created with “efficiency similar to business batteries when it comes to cost and discharge fee, cycle life and power densities.” These might sometime wind up in medical units, wearable electronics or tiny flying drones, as an example. To see how they did it, examine the video after the break.
