With a fast growth of the renewable energy market, the demand for high-performance energy storage increases rapidly. Lithium-ion batteries (LIBs) are regarded as one of the best energy storage solution to power cell phones, laptops and electric vehicles. However, the capacity and the cost are still below the expectation for many application fields. Here, we report a low-cost, large-scalable waste tire-derived carbon and metal oxide composite anode for lithium ion batteries. Carbon composite powders were prepared with carbon recovered from used tire powders and 25 wt. % of the select metal oxides to form composite electrodes. With such controlled amount of the metal oxide and the unique pore size distribution of the tire-derived carbon as the absorbing matrix, the volume change and the degradation of the electrodes are minimized. The composite anode shows a very stable electrochemical performance with a capacity of over 650 mAh g-1 after 300 cycles at a current density of 40 mA g-1. In the meantime, we also provided solutions to improve the first cycle efficiency. We will report in detail about the synthesis and characterization of the carbon composite electrodes. This study provides a new pathway for inexpensive, environmentally benign and value-added waste tire-derived products for energy storage applications.
