3D printing tiny batteries | Harvard School of Engineering and Applied Sciences

In this video, 3D printing is used to deposit a specially formulated "ink" through a fine nozzle to build a microbattery's anode layer by layer. Unlike an office inkjet printer that dispenses ink droplets onto paper, these inks are formulated to exit the nozzle like toothpaste from a tube and immediately harden into thin layers. The printed anode contains nanoparticles of a lithium metal oxide compound that provide the proper electrochemical properties. To read more about the research, please visit http://hvrd.me/rDgoe.
