MIT Scientists Made A Battery From The Carbon Dioxide Captured From Power Plants


The researchers at the MIT developed a battery using the carbon dioxide captured from power plants. The method is more straightforward than using metal catalysts to turn CO2 into specific chemicals which it’s still challenging. And the best part of it is that the new battery can convert carbon dioxide into a solid mineral carbonate as it discharges.

Even though it is only a project in its early phases of development, the MIT achievement might pave the roads to better electrochemical carbon dioxide conversion reactions which are the ultimate goal in cutting off emission of the greenhouse gas into the Earth’s atmosphere. The MIT scientists managed to create the new battery using lithium metal, carbon, and a specific electrolyte the engineers developed for this project.

As we speak, power plants use approximately 30% of the electricity they produce only to power up their carbon dioxide capturing equipment, so, the new MIT-made battery could reduce the costs significantly.

The chemistry behind the carbon dioxide capture can be employed in the development of carbon-dioxide-loaded electrolytes which are one of the three essential parts of the new battery MIT came up with.

Thanks to that, the new approach can be used in the power plant waste stream to ensure the material needed for the production of the electrolyte, one of the crucial parts of the new battery.

Lately, the scientists worldwide are struggling to develop reliable lithium-carbon-dioxide batteries which use the gas as a reactant during discharge. However, these would require the use of metal catalysts which are not fully comprehended and their reactions are not yet easy to handle.

Fortunately, the MIT scientists used the gas in a liquid state and managed to achieve a stable electrochemical carbon dioxide conversion by employing only one electrolyte.
