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.
