Iranian Scientists Develop First Fully Rechargeable Carbon Dioxide Battery

Iranian researchers at the University of Illinois at Chicago have designed lithium-carbon dioxide batteries that can be operated in a fully rechargeable manner.

According to UIC Today report, researchers have successfully tested a lithium-carbon dioxide battery prototype running up to 500 consecutive cycles of charge/recharge processes.

“Lithium-carbon dioxide batteries have been attractive for a long time, but in practice, we have been unable to get one that is truly efficient until now,” said Amin Salehi-Khojin, associate professor of mechanical and industrial engineering at UIC’s College of Engineering.

“The accumulation of carbon not only blocks the active sites of the catalyst and prevents carbon dioxide diffusion, but also triggers electrolyte decomposition in a charged state,” said Alireza Ahmadiparidari, first author of the paper and a UIC College of Engineering graduate student.

Salehi-Khojin and his colleagues used new materials in their experimental carbon dioxide battery to encourage the thorough recycling of both lithium carbonate and carbon. They used molybdenum disulfide as a cathode catalyst combined with a hybrid electrolyte to help incorporate carbon in the cycling process.

Specifically, their combination of materials produces a single multi-component composite of products rather than separate products, making recycling more efficient.

“Our unique combination of materials helps make the first carbon-neutral lithium carbon dioxide battery with much more efficiency and long-lasting cycle life, which will enable it to be used in advanced energy storage systems,” Salehi-Khojin said.

The findings are published in the journal Advanced Materials.
