As energy storage devices, batteries play a vital role
in people's production and life.
Integrating battery technology with other advanced technologies to complete energy storage functions while giving them more new functions is one of
the frontiers and directions of today's battery research and development.
Electrochromic battery is a new type of battery prepared by integrating battery technology and electrochromic technology, which has unique color change characteristics, can display the capacity of the battery through its own color difference, and establishes an interactive interface
between the user and the battery.
However, as a new research field, electrochromic batteries are facing many challenges at this stage, and their capacity, charging time and cycle stability performance are not ideal
.
Recently, Zhao Zhigang's research group at the Suzhou Institute of Nanotechnology and Nanobionics, Chinese Academy of Sciences has developed a high-capacity, fast-charging electrochromic battery
.
This kind of battery uses tungsten oxide (W18O49) nanowire and metal aluminum as positive and negative electrodes respectively, with unique new advantages: (1) can establish an interface with the user to identify the amount of capacity through color change, the power is full when the transparent state, the color gradually turns blue to mark the beginning of the storage power consumption, and the darkest color represents the exhaustion of power; (2) This battery can be quickly charged by adding a trace amount of hydrogen peroxide (full in 8s), or it can be charged by traditional external power supply and self-charging using oxygen in the air; (3) The battery capacity is more than 6 times higher than
that of similar batteries.
The results of the study have been published in the international journal Angew.
Chem.
Int.
Ed, opens a new path
for the future development of electrochromic batteries.
The above research work has been strongly supported
by the National Natural Science Foundation of China.
