A team of engineers from the Massachusetts Institute of Technology (MIT), USA, has developed a rechargeable lithium-ion battery in the form of an ultra-long fibre. The battery is 140mts long and is the longest battery ever made. The battery can be used to charge a wide variety of wearable electronic devices and to make 3D-printed batteries virtually. It can also be used in the future for self-powered communications, sensing and computational devices and can be woven into fabrics too. The fibre’s use was demonstrated in a Li-Fi communications system, where pulses of light were used to transmit data to establish an optical data link between two woven fabric devices.

The first battery was created in 1798 by Alessandro Volta.
