As conversion material, ZnMn₂O₄ has a high theoretical specific capacity as an anode for Lithium‐ion batteries. This paper has designed a facile method to prepare urchin‐like ZnMn₂O₄ architectures with high quality and well crystallinity. The resultant urchin‐like ZnMn₂O₄ architectures exhibit high discharge capacity and excellent cycling stability. The initial discharge capacity of urchin‐like ZnMn₂O₄ architectures is 1167 mAh g⁻¹ at 0.4 A g⁻¹ and the electrode materials could maintain high reversible capacity of 889 mAh g⁻¹ after 150 cycles. Even in the high current density of 1 A g⁻¹, the electrode of urchin‐like ZnMn₂O₄ can keep a high reversible capacity of 578 mAh g⁻¹ after 300 cycles. The improved electrochemical performance can be ascribed to the urchin‐like architectures of the as‐prepared ZnMn₂O₄, which could be conducive to the transmission of lithium ions and electrons and provide sufficient void spaces to tolerate the volume change during the Li⁺ intercalation. These results revealed that as‐prepared urchin‐like ZnMn₂O₄ architectures would be a promising anode for high performance Lithium‐ion batteries.

具有增强的电化学锂存储能力的Urchin类ZnMn2O4结构的轻松合成

作为转换材料，ZnMn ₂ O ₄作为锂离子电池的负极具有较高的理论比容量。本文设计了一种简便的方法来制备具有高质量和良好结晶度的类似海胆的ZnMn ₂ O ₄结构。所得的类似urchin的ZnMn ₂ O ₄结构具有高放电容量和出色的循环稳定性。在0.4 A g ^-1时，类顽固的ZnMn ₂ O ₄结构的初始放电容量为1167 mAh g ^-1，电极材料可保持889 mAh g ^-1的高可逆容量。150个周期后。即使在1 A g ^-1的高电流密度下，类顽固的ZnMn ₂ O ₄电极在300次循环后仍可保持578 mAh g ^-1的高可逆容量。改善的电化学性能可以归因于所制备的ZnMn ₂ O ₄的类似海胆结构，这可能有助于锂离子和电子的传输，并提供足够的空隙空间以容忍Li ⁺嵌入过程中的体积变化。这些结果表明，制备的类似海胆的ZnMn ₂ O ₄结构将是高性能锂离子电池的有希望的阳极。
