In what way do we call it a revolution in wearable battery technology? Researchers from MIT have developed the world’s most extended flexible battery. A rechargeable long-fiber lithium battery. This battery is about 140 meters long and may extend much longer.

Materials Today reported that battery length proves the possibility of forming materials at extensive lengths.

The battery was made for the first time in thermal drawing, enabling us to make any 3d battery in all possible forms. According to the fiber battery’s developer team, innovation opens up countless opportunities to manufacture self-powered communication devices — i.e., not requiring an external energy source — sensors, wearable computers, and machines whose batteries are part of their structure.

Electronic Components of Battery

the researchers previously made fibres that contain many electronic components but require an external energy source. Now, thanks to the folding and washing fibre one. The devices can operate without any external power source.

An earlier report suggested that lithium could be the future of its technology industry. That invention seems to be living proof of that.

The new fibre battery was made using new gels and using a fibre drawing system. At a press conference at the University of Massachusetts, postdoctoral student toral khodiev noted that previous attempts to manufacture fibre batteries relied on putting essential materials on the outer surface of fibres.

This time, these vital substances, in addition to lithium, exist inside the fibres. And exist insulated with a protective layer that makes them more stable and water-resistant. The fibre battery can also stand made up to a kilometre long, with high endurance and superior practical capabilities.

Fibre Battery

A 140-meter fibre battery can charge smartwatches or mobile phones with a capacity of up to 123 mah.
“The beauty of our style is that more than one device can be included in the fibre itself,” says postdoctoral student Jung t. lee.

The team included a led one and a lithium-ion battery within the fibre itself. And Jung lee believes three or four devices could stand included in the future. By having several devices in the duplicate threads, we might exist able to form a computer in the fibres in the future.

The material can also exist used in 3d printing to design shapes as needed and form solid bodies. To illustrate this, a toy existed used in the form of a submarine and wrapped in fibres that powered it.
“This is the first experience of 3d printing using fibre batteries.”  This does not require adding any other material because everything is already in fibre, all minerals and active materials. It stands printed only one step for the first time.”


The researchers have applied for a patent and exist moving toward making high-capacity batteries of different materials.

This is the latest in its technology. Earlier this year, a team of researchers in Singapore created a “paper battery” with almost two human hairs. At Stanford University, scientists have developed flexible, lightweight solar panels for electric power vehicles and light spaceships.
