Flexible Thin-film Battery Created at Rice University

Researchers at Rice University created a flexible material that combines the characteristics of a high-energy battery and high-powered supercapacitor that has potential use in portable, wearable electronics.

The capacitor is approximately a hundredth of an inch thick and is made of nanoporous nickel-fluoride electrodes that are layered around a solid electrolyte. It can be scaled up for devices by increasing the size or adding additional layers. After testing the device through 10,000 charge-discharge cycles and 1,000 bending cycles, it was able to maintain 76% of its capacity. The team will continue testing the material using standard manufacturing techniques that may enable the battery to become even thinner.
