Work is underway to make batteries powerful and modern in the face of changing requirements. Scientists at the University of British Columbia have now developed a battery that works even after being pulled, twisted, and accidentally washed in a washing machine.
This is because it is specially designed for circuits worn in electrical appliances or clothing. It is a joint effort of a professor, a Ph.D. student, and a postdoctoral scholar. Together they have changed the properties and appearance of the battery.
Zinc and manganese dioxide are crushed into fine pieces and wrapped in a rubber-like plastic-like polymer. This battery is made of very fine polymer. It is completely airtight and waterproof.
The battery continues to run even after turning and washing in the initial test.
Dr. Nok Tan Gwen, head of the team, says there is a huge market for flexible and robust batteries. Although such batteries have been made, the washable battery has not yet been invented, which is now first time.
Bihar Iranpur, a female scientist in the team, washed the new battery 39 times and maintained its usefulness. But research is now underway to make it harder. It has even been washed in large household and laundry commercial machines, but the battery remained intact.
On the other hand, zinc manganese is safer and less toxic than lithium-ion batteries.
The findings are published in the journal Advanced Energy Materials.
