An anonymous reader writes: Scientists have successfully 3D printed a Lithium-ion battery about the size of a grain of sand. This is truly amazing, with this kind of technology we can make batteries with many times the capacity of current day batteries, on the same size, or even smaller. It also has the potential to revolutionize nanotechnology.
Usually with devices on this scale the batteries are several times larger than the device itself. It is the perfect companion for all the nano devices being developed these days.
This type of microbattery will be incredibly useful for example in the field of medicine.
The scientists realized they could pack more energy if they could create stacks of tightly interlaced, ultrathin electrodes, the electrodes are smaller than the width of a human hair.
“Not only did we demonstrate for the first time that we can 3-D-print a battery, we demonstrated it in the most rigorous way,” said Jennifer Lewis, Ph.D., senior author of the study.
