Who hasn't been confronted with situations like these: The smartphone displays “0 %” and shuts down while you are watching the latest episode of your favourite tv show. Now the battery of the cell phone needs to be charged to see the relieving “100 %” again. In today’s world we are constantly surrounded by state of charge displays, e.g. in smartphones, e-bikes or electric cars. A surprising amount of science is doing the heavy lifting the background to provide us with the handy state of charge of our electric devices.
In this context Prof. Dr. Ulrich S. Schubert and the scientists of his working group Oliver Nolte, Dr. Robert Geitner and Dr. Martin D. Hager present a new method to determine the state of charge in organic batteries. Contrary to established methods which rely on the measurement of electric voltages the new method uses infrared light to precisely and rapidly access the state of charge of batteries. In comparison the newly developed method is faster and provides a greater accuracy over longer periods of time.
