| Popis: | The ZnMn2O4/V2CTx composites with a lamellar rod-like bond structure were successfully synthesized through high-temperature calcination at 300 °C, aiming to enhance the Li storage properties of spinel-type ZnMn2O4 anode materials for lithium-ion batteries. Moreover, even though the electrode of the composites obtained at 300 °C had a nominal specific capacity of 100 mAh g−1, it exhibited an impressive specific discharge capacity of 163 mAh g−1 after undergoing 100 cycles. This represents an approximate increase of 64% compared to that observed in the pure ZnMn2O4 electrode (99.5 mAh g−1). The remarkable performance of the composite can be credited to the collaborative impact between ZnMn2O4 and V2CTx, leading to a substantial improvement in its lithium ion storage capacity. Therefore, this study offers valuable insights into developing cost-effective, safe, and easily prepared anode materials. |
