Chinese scientists have developed a portable power source that can be woven into materials like cotton.

Scientists at Fudan University in Shanghai have developed battery technology that can be woven into fabrics like cotton.

The researchers, Wei Wang and his colleagues, created a lithium ion battery fiber by designing and developing carbon nanotube (CNT) composite yarns that are wound around a cotton fiber. The fibers have a diameter of about 1mm and can be woven into textiles or fabrics and can be easily integrated into flexible wearable technology products.

According to Wei Wang, the fiber lithium ion battery can be used as a power source for wearable electronics. Creating a good power source that can be directly and seamlessly integrated into wearable tech devices has always been something that developers are interested in and a power source that can be woven into fabrics holds a lot of potential. The fiber lithium-ion battery can become key to developing new wearable electronics that wouldn't require a separate and bulky power source or extra compartments for batteries. The new type of batteries can also be potentially used in other industries and machines – as carpets or seats for automobiles, for example.
