Recently, the U.S. Department of energy Oak Ridge National found a new method for recycling waste tires.

The research team of parans paranthaman and Amit naskar found that the pyrolytic carbon black material can be extracted from the pretreated waste tires after high-temperature decomposition.

Carbon black is similar to graphite and can act as the positive electrode of the battery, but the effect of carbon black is better. In the battery test, it is found that the lithium battery made of carbon black has a larger capacity than the lithium battery made of traditional graphite. This is because the carbon black contains porous microstructure, so it can obtain a larger surface area than graphite.

Moreover, this technology also has certain advantages in manufacturing cost. At present, Oak Ridge National is looking for manufacturers to negotiate and hope to commercialize it.
