by Scientists in Sweden have invented a new kind of battery that can assume any form.
The soft, toothpaste-like battery could turn the electronics into a single device by installing, according to the Linköping University team, which it developed.
Potential applications include medical devices, portable devices and even robots of the next generation.
“The texture is a bit like a toothpaste,” said Aiman Rahmanudin, assistant professor at Linköping University.
“For example, the material can be used in a 3D printer to the battery as you want. This opens up for a new type of technology.”
The battery uses electrodes made of lignin-one sustainable by-product from paper production and ensures an environmentally friendly alternative to traditional technologies based on lithium.
So far, stretchy batteries have rare to rare, environmentally harmful materials for functioning.
“Since the materials are conjugated polymers and lignin in the battery, the raw materials are plentiful,” said Mohsen Mohammadi, a postdoctoral at Loe who headed research.
“By converting a by -product like lignin into a high -quality raw material such as a battery material, we contribute to a more circular model. So it is a sustainable alternative.”
A prototype created by the team was able to double its original length and loaded more than 500 times without significant reduction in performance.
The researchers are now planning to continue the development of the battery in order to increase the electrical voltage and further improve their benefits.
“The battery is not perfect. We have shown that the concept works, but the performance has to be improved,” said assistant professor Rahmanudin.
“The voltage is currently 0.9 volts. So now we will look at to use other chemical compounds to increase the voltage.”
The breakthrough of the battery was described in a study entitled “Make it Flow from firm to liquid: Redoxactive electrical fluid for intrinsically stretchy batteries”, published in the journal Science progress on Friday.
