Strategy shown for novel tire-derived carbon anodes for sodium-ion batteries

Researchers have demonstrated a process to prepare morphologically tailored carbon materials with good electrochemical capacity Shown are scanning transmission electron microscopy of sulfonated tire-derived carbon treated at 1,100 C (left) and data from a long-cycle stability test of the same sample at a current density of 20 mA/g. Both charge discharge curves are nearly identical (right).and stability for sodium-ion battery anodes. Hard-carbon materials are considered as one of the most promising anode constituents for the emerging sodium-ion batteries. 

Tire-derived carbons obtained by heat-treating sulfonated tire rubber had good sodium storage, with good electrochemical stability. The interlayer distances determined from high-resolution scanning transmission electron microscopy of crystalline areas were determined to be ideal for sodium intercalation. Recycling hazardous wastes to produce value-added products is becoming essential for the sustainable progress of society. The strategy used in this research may be applied to other rechargeable batteries including potassium-ion batteries to achieve even higher electrochemical performance and cycling stability.
