Research on electrochemical energy storage is color blindness affected

How to make energy storage devices with smart function of changing color?

Energy storage devices with the smart function of changing color can be obtained by incorporating electrochromic materials into battery or supercapacitor electrodes. In this review, we explain the working principles of supercapacitors, batteries, and electrochromic devices.

What are electrochromic energy storage devices (eesds)?

Electrochromic energy storage devices (EESDs) including electrochromic supercapacitors (ESC) and electrochromic batteries (ECB) have received significant recent attention in wearables, smart windows, and colour-changing sunglasses due to their multi-functionality, including colour variation under various charge densities.

Why do rudimentary electrochromic energy storage devices only retrieve limited consumed energy?

Therefore, the rudimentary electrochromic energy storage devices can only retrieve limited consumed energy due to the bistable nature of electrochromic materials (i.e., strong electrostatic interactions between inserted cations and electrochromic materials).

What are Zn anode-based electrochromic energy storage devices?

The Zn anode-based electrochromic energy storage devices (EESDs) provide a promising strategy to overcome the contradiction of electrochromism and energy storage for efficient devices. In this regard, the device configuration can endow the electrochromic devices with superior electrochromic performance and excellent energy recovery efficiencies.

What are flexible and stretchable electrochromic energy storage devices?

Such flexible and stretchable electrochromic energy storage devices have multiple functionalities and could be potentially implemented for wearables, smart building, electric vehicles, and smart display.

What does intercalation mean in electrochromic energy storage?

In short, for rudimentary electrochromic energy storage devices, the more ions intercalated means the more energy they consume, while in metal anode-based electrochromic energy storage devices, the more ions intercalated means the more energy they provide.
