Multifunctional portable energy storage

Why do we need a large-scale energy storage system?

As renewable energy capacity continues to surge, the volatility and intermittency of its generation poses a mismatch between supply and demand when aligned with the fluctuating user load. Consequently, there’s a pressing need for the development of large-scale, high-efficiency, rapid-response, long-duration energy storage system.

How can multifunctional composites improve energy storage performance?

The development of multifunctional composites presents an effective avenue to realize the structural plus concept, thereby mitigating inert weight while enhancing energy storage performance beyond the material level, extending to cell- and system-level attributes.

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.

What are electrochemical energy storage devices?

Among various energy systems, electrochemical energy storage devices such as batteries and supercapacitors have attracted worldwide attention for use in electric-powered transport, portable electronics, and biomedical devices.

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.

How are energy storage devices classified?

Energy storage devices have been classified based on the type of electrodes involved in electrochemical reactions. During these electrochemical reactions in some of the materials, the electrode’s colour variation occurs due to oxidation and reduction reactions.
