Scientists 3D-print 300m lithium-ion batteries

hypnosec (2231454) writes "Harvard scientists have managed to 3D-print 300m lithium-ion batteries – the size of grain of sand – that could possibly pave way for new era of micro-electronics. The 3D-printed battery is thinner than that of a human hair and can be used to supply electricity to tiny robotic devices, medical implants as well as those devices that have been powerless for the want of such tiny batteries. According to Jennifer Lewis, a materials scientist at Harvard, 3D-printing of the battery was possible thanks to two important developments. Lewis’ first invention is “what she calls functional inks that can solidify into batteries and simple components, including electrodes, wires, and antennas." Second is the development of nozzles and high-pressure extruders that are used to squeeze out the batteries and other components from the 3D-printer."
