Synthesis of Li4Ti5O12 anode materials with high specific capacity for lithium-ion batteries |
| 초록 |
We prepared Li4Ti5O12-y solid solutions by one-step solid-state carbon thermal reduction reaction. Samples of Li4Ti5O12-y solid solutions are synthesized with different content of carbon black. The presence of carbon black act as reductant. The formation mechanism of Li4Ti5O12 in the presence of carbon (carbon black) was investigated. Moreover, the effect of Ti3+ on the electrochemical performance of the Li4Ti5O12-y solid solutions has been investigated systematically. Among all samples, the sample with 2% carbon black additive exhibited the highest discharge capacity and best cycling stability. Our findings reveal that the surface modification with carbon black can improve the electrical conductivity and Li+ diffusion coefficient and improve rate capacity and cycling stability significantly. |
