 Lithium-carbon dioxide batteries are attractive energy storage systems because they have a specific energy density that is more than seven times greater than commonly used lithium-ion batteries. Until now, however, scientists have not been able to develop a fully rechargeable prototype, despite their potential to store more energy.

Researchers at the University of Illinois at Chicago are the first to show that lithium-carbon dioxide batteries can be designed to operate in a fully rechargeable manner, and they have successfully tested a lithium-carbon dioxide battery prototype running up to 500 consecutive cycles of charge/recharge processes.

Their findings are published in the journal Advanced Materials.

Energy storage membrane set to revolutionize rechargeable batteries

membrane-1-580x384

This simple looking membrane could change the industry.

If you want a rechargeable battery in a power-hungry device today, the only real choice is a lithium-ion battery. They are heavy, quite large depending on how much charge you need, and volatile. They also have a high cost and limited life span.

A replacement for lithium-ion has long been sought after, and recently there have been some breakthroughs such as the jelly-like polymer battery. However, researchers at the National University of Singapore may have come up with the best solution yet in the form of an new energy storage membrane…
