A team of Chinese researchers from Fudan University develop a new type of lithium-ion batteries in the form of textile fibers, which could be integrated into clothing or clothing accessories.
One kilogram of this innovative material would have the capacity to store about 85.69 watt-hours (Wh), thus surpassing even the performance of an iPhone 12 Pro Max battery, whose 228-gram battery has a capacity of 14.13 Wh, that is, 61.97 Wh per kilogram.
According to the authors of the project, batteries made with fiber continue to function after being washed, bent and even pierced by sharp objects, and they maintain approximately 90.5% of their original capacity after 500 complete charge and discharge cycles; review RT press release
One of the tests carried out consisted of passing a 1,300 kilogram car over this material while it was being used to charge an iPad, without interrupting the charging process.
Experts hope that the technology will prove useful in the smart clothing market and that it will be used to charge portable electronic devices such as telephones, smart watches or small medical devices. As a prototype, they created a shirt with lithium ion fibers integrated into the fabric.//MT
