What are flexible energy storage devices?

To date, numerous flexible energy storage devices have rapidly emerged, including flexible lithium-ion batteries (LIBs), sodium-ion batteries (SIBs), lithium-O 2 batteries. In Figure 7E,F, a Fe 1−x S@PCNWs/rGO hybrid paper was also fabricated by vacuum filtration, which displays superior flexibility and mechanical properties.

What are the different types of flexible batteries?

This review discusses five distinct types of flexible batteries in detail about their configurations, recent research advancements, and practical applications, including flexible lithium-ion batteries, flexible sodium-ion batteries, flexible zinc-ion batteries, flexible lithium/sodium-air batteries, and flexible zinc/magnesium-air batteries.

What is a flexible battery?

Different from the conventional batteries that utilize rigid and bulky electrodes, current collectors, metal anodes, liquid electrolytes, and packages, flexible batteries require the flexibility of each component to accommodate diverse shapes or sizes.

What is a flexible lithium ion battery?

In contrast to conventional lithium-ion batteries necessitating the incorporation of stringent current collectors and packaging layers that are typically rigid, flexible batteries require the flexibility of each component to accommodate diverse shapes or sizes.

What materials are used in a flexible battery?

Additionally, the flexible battery often use highly conductive materials, such as carbon-based materials, hybrid nanocomposites, and conductive polymers as electrodes to ensure good mechanical performance and efficient electron transport.

Are flexible lithium-ion batteries the future of energy storage?

Flexible electronics is a rapidly expanding area that requires equally flexible energy storage technologies. Flexible lithium-ion batteries (FLIBs) have emerged as a promising candidate, poised to revolutionize applications ranging from wearable devices and flexible displays to biomedical implants and energy textiles.
