Mit created a battery absorbing carbon dioxide

Researchers of the Massachusetts Institute of Technology have developed a new type of battery, which in the discharge process converts carbon dioxide into mineral carbonate.

The battery consists of lithium, carbon and special electrolyte. Although liquid is usually not used in lithium devices, but the team decided to combine several technologies at once. This allowed them with the help of electrochemical reactions to achieve capture and conversion CO2. However, due to the low level of activity, insufficient to the desired level of discharge, it was required to be pre-activated using a solution of amines speaking as a catalyst.

Combining components made it possible to increase the operating voltage and ensure the constant absorption of carbon dioxide. However, due to the gradual degradation of the components, the service life of the prototype is limited to 10 charging cycles, so there will be more years of research, before a full-fledged commercial product appears. However, a new battery type can help reduce greenhouse gas emissions into the atmosphere due to the conversion of carbon dioxide.

The carbon cathode is shown at the microscope after discharge, on the surface of which carbonate compounds have accumulated.

Scientists say that only began to study the possibilities of combining two different areas, but they were interested in such a combination. In the future, it can lead to unexpected results in the fight against greenhouse gases.

Science is more and more to take care of the environment. Recently, scientists of Binghemton University presented
