Fiber batteries, also known as fiber-shaped batteries or fiber-based batteries, are a type of battery that integrates energy storage capabilities into a flexible and lightweight fiber form factor. These batteries are designed to be woven into textiles or incorporated into wearable devices, enabling the creation of smart clothing and accessories that can store and deliver power.

Fiber batteries typically use thin, flexible electrodes and electrolytes to maintain their flexibility and durability. They can be made using various battery chemistries, such as lithium-ion or zinc-based chemistries, depending on the specific requirements of the application.

Fiber batteries have the potential to revolutionize the field of wearable electronics by providing a compact and lightweight power source that seamlessly integrates into clothing and accessories, enabling new functionalities and applications in areas such as health monitoring, communication, and fashion.
