Lithium battery: new technology allows it to absorb CO2 energy


The severe issue of the carbon dioxide is no news to anyone, we all know that our atmosphere contains alarming levels of this gas due to all the pollution generated by the human being, but now a technology fruit of the hard work led by a group of scientists, may be about to change this.

The resolution of the problem of the excess CO2 in the atmosphere has been one of the points that has deserved the attention of scientists, since every day its presence increases, enhancing effects not only harmful to the planet directly, but also to our health. The present system of prevention of emissions of carbon dioxide to the atmosphere, although functional, requires in return, enormous amounts of energy, according to MIT.

According to a study dated from 2014, this type of system requires about 30% of the energy that can be produced by a power plant, creating problems not only by generating more pollution in this process, but also for not giving a destination to carbon dioxide withheld. The idea of finding uses for the excess of carbon dioxide is not new, with attempts even been made to make it a viable source of fuel, and based on that idea, an MIT team came up with the idea of creating a battery system that absorbs dioxide of carbon directly from the electrical stations, converting this gas into an electrolyte, which is one of the three components of this revolutionary battery.

Lithium and carbon dioxide batteries usually require metal catalysts to work, because CO2 is poorly reactive, making the production of this type of batteries quite expensive and unstable, but the team led by mechanical engineer Betar Gallant, was able to achieve an electrochemical conversion of carbon dioxide using only a carbon electrode, and the solution to it was by means of the use of carbon dioxide in its liquid state, incorporated into an amine solution.

In doing so, scientists have demonstrated for the first time that by using these advanced techniques, carbon dioxide can become more prone to electrochemistry. Although this is not the most logical approach, the truth is that this extravagant combination has triggered new and interesting reactions that allow the discharge of energy, and the conversion of carbon dioxide.

Although the research is not yet at the point where it will allow the technology to launch in the commercial market, the experiments demonstrate that it is not only more efficient, but economical and safe, although there is still room for new improvements that will certainly exist before these can reach the market, for now these batteries can only withstand about 10 cycles of charge and discharge.
