Are you ready for a transparent battery inside of your transparent mobile phone? What, you don't have a transparent phone? That's, apparently, because powerful transparent batteries haven't been invented, until now.
A report in the New Scientist says transparent batteries based on research coming out of Stanford University could happen in he next few years.
Lead researcher says Yi Cui says the transparency of the batteries is tunable, although there is a tradeoff between transparency and the ability to store energy. According to the article, the batteries should have uses beyond novel phone designs:
"Cui believes we could see transparent batteries in consumer devices in the next two to four years, depending on how easy it is to scale up the manufacturing process. The see-through components also have a scientific application, however: researchers can use optical detecting tools to study a battery's chemical reactions as they happen, which previously was impossible."
