Carbon powders recovered from waste tires are considered as one of the most promising anodes for both lithium-ion and sodium-ion batteries. The tire-derived carbons obtained by pyrolyzing the acid-treated tire at 1100 °C. The carbon interlayer distances for crystalline carbon areas were determined to be 4.7 Å. These values are ideal for lithium and sodium intercalation. When the pyrolysis temperature is increased from 1100 to 1600°C, the capacity of the plateau below 0.2 V increases dramatically and this could help increase the full cell energy density. The 1600°C treated carbon shows a capacity of 203 mAh g^-1after 100 cycles with sodium-ion batteries. We will report the current status of the tire-derived carbon powder scale up efforts and its use in energy storage applications.
