ZnMn₂O₄/V₂CT_x Composites Prepared as an Anode Material via High-Temperature Calcination Method for Optimized Li-Ion...

The ZnMn₂O₄/V₂CT_x 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 V₂CT_x, 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.
