When charging, the battery that can absorb carbon dioxide

It was reported on May 31. According to the Spanish Energy Daily website reported on May 28, a research team in the University of Cambridge, England, developed a low -cost device that can selectively capture carbon dioxide gas during charging.

Then, during discharge, carbon dioxide can be released in a controlling manner, and it can be collected again or responsible for processing. This super capacitor device is similar to the rechargeable battery, only the size of the coin, and some components are made of sustainable materials such as coconut shells and seawater. Super capacitors may help develop carbon capture and storage technology, and the cost is low. About 35 billion tons of carbon dioxide each year is discharged into the atmosphere. It is urgent to find a solution to eliminate these emissions and solve the climate crisis. At present, the most advanced carbon capture technology requires a large amount of energy and expensive. Super capacitors are composed of two electrodes with positive charge and negative charge. The research team attempts to switch from negative voltage to positive voltage to extend the charging time of previous experiments, thereby improving the ability of supercapacitors to capture carbon. Dr. Alexander Form Solse, who studied the leader of the leader and the Department of Chemistry of Cambridge University, said: We found that by slow switching between the electrode boards, we can capture the carbon dioxide twice as much as before. Formia said: Compared with the amine heating process currently used in industry, our super capacitor charging and discharge process may consume less energy.

He also said: We will improve the exact research mechanism of carbon dioxide and improve. Then come to solve the problem of expanding scale.
