Does that mean you could tell how full a battery is just by looking at it? It sure sounds like it.

One Sentence:
"Their inherent optical characteristics can therefore directly reveal the real time energy levels stored within."

Another sentence:
"The electrochromic displays developed here can change color based on their stored levels of energy and the product will have broad implications as next-generation smart window materials for buildings and portable energy storage."

What do you think?
