Batteries are key components of portable electric devices. Electrochromic batteries enable the direct readout of a battery's energy levels through a real-time color change. However, the field is still rather young and many unsolved problems exist, such as a low energy storage capacity and a time-consuming charging process.

Zhigang Zhao, Suzhou Institute of Nano-Tech and Nano-Bionics, China, and colleagues have successfully developed a high-capacity electrochromic battery. Two common materials, aluminum metal and tungsten oxide (W18O49), were selected to construct the electrochromic battery. The device shows many advantages over its traditional counterparts, including a distinguishable color change corresponding to different charge levels.

The electrochromic battery also exhibits a high capacity, as well as fast charging within 8 seconds after the addition of a small amount of hydrogen peroxide. This study may serve as a starting point for the future rational design of new high-performance electrochromic batteries.
