is that a battre???

This is what happen if Japan researcher get too passionate and invent a polymer based rechargeable battery that is flexible and transparent. These researchers from Waseda University that designed this battery announced that this battery consists of a redox-active organic polymer film around 200 nanometers thick and you only need “1 second” to full charge this battery. How efficient is this? However, these batteries can only be used in applications that require high-power capability rather than high-energy density.
