a cotton t-shirt may one day charge your cellphone - energy storage devices
Two engineers at the University of South Carolina conducted a study showing a modified store --bought T-
The shirt can be charged like a super capacitor.
"We wear fabrics every day," said Li Xiaodong, a professor of mechanical engineering at the school.
"One day, our cotton
The shirt can have more functions;
For example, a flexible energy storage device that can charge a mobile phone or iPad.
Li and his colleagues are in a shop. bought T-
Shirt, then soaked in fluoride solution, baked at high temperature in oxygenfree oven.
After removal, the resulting fiber is converted from cellulose to activated carbon that can store the charge.
"We will see the rolling soon.
"There are more and more mobile phones and laptops on the market," Li said, according to the Innovation News Daily . ".
"But to achieve this, a flexible energy storage device is needed.
The engineers pointed out that activated carbon textiles are like super capacitors because they have "particularly high energy storage density ".
The two men applied a layer of nano-manganese oxide to the shirt fibers, which greatly improved the electrical properties of the materialStorage capability.
"This creates a stable, high
Perform a super capacitor, "said Li.
The team found that fabric capacitors can be charged and discharged thousands of times with minimal performance loss.
The method used to make fabric capacitors is not only cheap, but also green and does not use chemicals that are harmful to the environment.
This study may lead to clothing and even furniture that one day can charge or even control certain electronic products.
