Scientists at the University of South Carolina have developed a T-shirt capable to store electrical power.

The T-shirt could pave the way for clothes that are able to charge phones and other devices.

Experts predict that new technologies including roll-up smartphones and laptops will be on the market soon.

These developments would spur on the need for “flexible energy storage”, said the professor behind the project.

Xiaodong Li, a professor of mechanical engineering at the university teamed up with post-doctorate researcher Lihong Bao to find a solution.

The pair wrote up their findings for the Advanced Materials journal.

They used a T-shirt bought from a local discount store, which was soaked in a solution of fluoride, dried and then baked in an oxygen-free environment at high temperature.

The fibres in the fabric converted from cellulose to activated carbon during the process, but the material remained flexible.

By using small parts of the fabric as an electrode, the researchers showed that the material could be made to act as a capacitor.

Capacitors store an electrical charge and are components of nearly every electronic device on the market.

By coating the individual fibres of the carbonized fabric with manganese oxide just a nanometre thick, the electrode performance of the fabric was further enhanced.

“This created a stable, high-performing supercapacitor,” said Prof. Xiaodong Li.

The hybrid supercapacitors proved resilient – even after thousands of charge-discharge cycles their performance did not diminish more than 5%, the researchers said.

“By stacking these supercapacitors up, we should be able to charge portable electronic devices such as cell phones,” Prof. Xiaodong Li added.

“We wear fabric every day. One day our cotton T-shirts could have more functions; for example, a flexible energy storage device that could charge your cell phone or your iPad.”
