Conductive networks of waste tire derived carbons were used to produce homogeneous composites via ball milling as a promising anode material for sodium-ion batteries. Sodium half-cells delivered reversible discharge capacities of 207 mAh g~(-1) at a current density of 37 mA g~(-1). Carbon composite materials showed impressive capacity retention with 88% after 100 cycles. Rate capability studies at 60°C yielded enhanced capacity of 300 mAh g~(-1). From these remarkable results, the waste-tire derived carbon composites enabled stable alloying and dealloying processes as promising anodes for SIBs. We will also report our recent results on reducing the first cycle loss with carbon electrodes.
