Univ of Illinois: Fully rechargeable LiCO2 battery
On September 25, a researcher at the University of Illinois at Chicago (UIC) announced that it was the first successful development of a fully rechargeable lithium battery prototype using carbon dioxide (CO2).
Fully rechargeable LiCO2 battery: advantages
LiCO2 batteries maintain an energy density that is more than seven times that of ordinary lithium ion batteries.
It is possible to store a larger amount of electricity with the same size.
There are merits such as EV cruising range greatly increased.
Conventional development:
So far, the research result of Massachusetts Institute of Technology (MIT) has been that the continuous charge cycle is as low as 10 times.
This development:
In this UIC study, we succeeded in operating for up to 500 continuous charging cycles for the first time.
The paper was published in Advanced Materials (published August 22).
UIC Faculty of Engineering: Associate Professor Amin Salehi Kojin
Lithium CO2 batteries have long been an attractive material.
However, until now it was not possible to create a truly practical battery.
In our research, we combine original materials.
As a result, we have successfully developed a “much more efficient and more continuous charge cycle” battery.
Midwest US: Illinois
Institutes other than the University of Illinois have been researching batteries for over 50 years.
Argonne National Laboratory: Developed EV Chevrolet “Volt” battery.
Northwestern University: Concentrated research institutes famous for materials science for batteries
