Carbon Black – The battery of the future

Researchers from the US Department of Energy’s Oak Ridge National Laboratory have recently developed a method to collect carbon black from old tires to turn it into a more efficient source of materials. than for Li-ion batteries.

According to the two scientists who led the research team, Parans Paranthaman and Amit Naskar, their research process is largely related to the pretreatment of tires and then pyrolysis of them to break down organic matter. muscle in the absence of oxygen. The product obtained from this process will be powdered black coal.

Carbon Black is known to have a chemical structure similar to graphite, the material used to make the anode of Li-ion batteries, however, the difference is man-made black coal.

The scientists also said that, after obtaining powdered black coal, they also tested them as anodes of Li-ion batteries and the results were quite surprising that black coal helps bring a high efficiency. than ordinary graphite.

This ability, as explained, is largely due to the char’s honeycomb microstructure, which provides a larger surface area for storing energetic charges.
