Flexible thin-film battery is high energy power source for wearable electronics

Flexible thin-film battery by Rice University researchers

Researchers around the globe are constantly looking for that magic material which is flexible, as well as powerful enough to power up wearable electronics that are going to be the trend in coming years. Rice University Laboratory are now one step closer to developing that very material which is both flexible behaves like a high-energy supercapacitor, ideal for modern day wearables. Sans any lithium, this 3D nanoporous layer on poly(ethylene terephthalate) has been developed which is hundredth of an inch thick and can last for 10,000 charge-discharge cycles and 1,000 bending cycles.



To create this battery supercapacitor, the team deposited a layer of nickel on a backing and bind it together to make 5-nanometer pores within the 900-nanometer thick nickel fluoride layer. Once this material was set, they added a sandwiched layer around an electrolyte of potassium hydroxide in Polyvinyl alcohol. After that the team tested it and found no degradation of pore structure after numerous charge-discharge cycles.

According to researcher Yang Yang this new revolutionary material behaves like a battery, and has the structure of a supercapacitor, making it a magic material for wearable devices and sleek design gadgets. The material has a very high power deliverance gradient and could change the way gadgets and gizmos will be designed in the coming years.

As we can clearly see, this is truly a magic material that comes as a blessing for wearables that require flexible and thin battery power systems. Not only wearable gadgets but this new technology could also be applied to numerous other 3D nano-porous materials in manufacturing sector.
