Stanford researchers invent transparent Li-Ion battery
Like the idea of a fully transparent cell phone, e-reader, or other device?
Stanford University graduate student Yuan Yang has come up with a way to make a see-through lithium ion battery, and it could pave the way for completely see-through flexible electronics (some partially transparent gadgets already exist). Developed in conjunction with Yi Cui, a professor of photon science at the SLAC National Accelerator Laboratory, the battery would cost nearly the same as a regular battery if produced on a mass scale, the creators say.
So how does one make a see-through power source? According to Stanford News, "Yang and Cui devised a mesh-like framework for the battery electrodes, with each 'line' in the grid being approximately 35 microns wide. Light passes through the transparent gaps between the gridlines; because the individual lines are so thin, the entire meshwork area appears transparent."
