Supercapacitors promise recharging of phones and other devices in seconds and minutes as opposed to hours for batteries. But current technologies are not usually flexible, have insufficient capacities, and for many their performance quickly degrades with charging cycles. Researchers at Queen Mary University of London (QMUL) and University of Cambridge have found a way to improve all 3 problems in one stroke. Their prototyped polymer electrode, which resembles a candy cane achieves energy storage close to the theoretical limit, but also demonstrates flexibility and resilience to charge/discharge cycling.
The technique could be applied to many types of materials for supercapacitors and enable fast charging of mobile phones, smart clothes and ...
