Transparent Lithium-Ion Batteries Could Lead to Translucent Devices

By Duncan Graham-Rowe of Nature magazine Flexible, transparent lithium-ion batteries have been made by a team of researchers at Stanford University in California, a technological leap that could spawn see-through electronic gadgets such as translucent iPads. Many electronic components can be fabricated to be transparent, but so far this hasn't been possible for the power supply, says materials scientist Yi Cui, who led the work, which is published today in Proceedings of the National Academy of Sciences . Batteries are normally made up of a pair of electrodes separated by an electrolytic solution, with something to conduct the current to an external circuit, and packaging to hold it all together.
