Li-ion batteries provide power to plug-in electric-vehicles and tires roll the vehicles around the town, and they seem to be 2 unrelated vehicle parts. Wait! Researchers from Oak Ridge National Laboratory (ORNL), U.S.A., have developed a new technology to recycle old tires into the material for the anode contact of li-ion batteries. The new process can be seen below.
Graphite is commonly used to produce the anode of li-ion battery. Now, ORNL's team uses a proprietary pretreatment to recover pyrolytic carbon black material from old tires, which is similar to graphite but man-made. When used in anodes of lithium-ion batteries, researchers found a reversible capacity that is higher than what is possible with commercial graphite materials. After 100 cycles of charging and discharging the new battery still measured nearly 390 milliamp hours per gram of carbon anode, which exceeds the best properties of commercial graphite.
ORNL plans to work with U.S. industry to license this technology and produce lithium-ion cells for automobile, stationary storage, medical and military applications.
