Can burnt Cotton and seawater make a sustainable battery?

Researchers and companies are increasingly turning to unconventional materials such as burnt cotton and seawater to create sustainable battery technologies. The Japanese firm PJP Eye has developed a unique battery using carbon from burnt cotton.

Is pyrolysing cotton good for batteries?

Pyrolysing cotton at high temperatures can produce carbon with a structure that makes it ideal for use in batteries (Credit: Alamy) Mining the lithium and other minerals we need for batteries is taking an increasing toll on the environment. There are alternative materials all around us though. Zip. The power's out.

How much cotton is needed for a battery cell?

Okina does say that a high temperature is required, above 3,000C (5,432F). And that 1kg (2.2lbs) of cotton yields 200g (7oz) of carbon – with just 2g (0.07oz) needed for each battery cell. The firm bought a shipment of cotton in 2017 and still hasn't used all of it, says Okina.

Could a cotton battery be used instead of an electrolyte?

Cotton could also be used in place of the electrolyte that facilitates the flow of ions between the cathode and anode, potentially creating more stable, solid-state batteries than those currently available, according to some researchers.

Can fiber batteries be woven into textiles?

“For practical applications, we need reels of high-performing fiber batteries that can be woven into large-area textiles,” says Peining Chen, a chemist and chemical engineer at Fudan University. Making fiber batteries that perform well boils down to the quality of the battery materials’ coatings.

How are fiber-shaped batteries made?

Researchers have made fiber-shaped batteries by twisting or winding together different battery materials, or coating them in layers onto polymer fibers or metal wires. Previous fiber batteries have been just centimeters in length, impossible to weave into large fabrics, and had low energy densities.
