To keep up with the “flexible thin film battery” that can be stretched, bent and twisted without halting the power supply., battery makers have to be more flexible. Literally. Enter Professor Markus Niederberger and his research team at ETH Zurich, who have developed a prototype for a
The battery is built like a sandwich, following the design of commercial batteries, according to an article on the university’s website. Between two stretchable current collectors is a cathode, a hydrogel electrolyte, a PDMS frame and sealing and an anode.
“To date, no one has employed exclusively flexible components as systematically as we have in creating a lithium-ion battery,” Niederberger told ETH News.
Niederberger said the possibilities for the foldable battery go beyond phones. The batteries could be useful to rollable displays for computers, smartwatches and tablets, or functional textiles that contain bendable electronics. The battery could even be sewn into clothing, he added.
