Candy cane-shaped supercapacitor could charge phones in secs
UK-based scientists have developed a candy cane-shaped supercapacitor that could charge mobile phones in seconds. The prototype achieves energy storage close to the theoretical limit, and is resilient to several charge/discharge cycles. Further, its interpenetrating structure enables the material to bend easily, swell and shrink without cracking, leading to greater longevity, researchers said.
