Improving the anode materials for lithium-ion batteries with a long activation process, poor cycle stability, and low Coulomb efficiency is of great significance for developing novel high-performance anode materials. Orthorhombic LiVMoO₅ with high specific capacity was applied to the anode field of lithium-ion battery for the first time. However, the activation process led to its poor cyclic performance. By adopting a novel nano-transformation treatment process in a water and oxygen environment, we effectively avoided the long-term activation process. The specially treated LiVMoO₅ electrode (STLVME) exhibited excellent reversible specific capacity (∼1100 mA h g⁻¹) and rate cycle stability (capacity retention rate ∼100%). Furthermore, GITT and EIS also showed that compared with the primitive LiVMoO₅ electrode (LVME), smaller internal resistance and a higher Li⁺ diffusion coefficient were caused using the novel treatment process, significantly improving the rate cycle stability. Using in situ XRD and ex situ characterization, we illustrated the lithium storage mechanism of LVME and STLVME. In addition, the practical application potential of LVME and STLVME was also explored by assembling the full cells. Because the long-term activation process was effectively avoided, the full-cell exhibited amazing cycle stability, indicating that STLVME can be considered a promising potential anode for practical applications in energy storage devices.

一种通过电极催化诱导锂化双金属氧化物纳米转化的新策略，避免了先进锂离子电池的长活化过程

改进活化过程长、循环稳定性差、库仑效率低的锂离子电池负极材料，对于开发新型高性能负极材料具有重要意义。高比容量的正交LiVMoO ₅首次应用于锂离子电池负极领域。然而，激活过程导致其循环性能较差。通过在水氧环境中采用新型纳米转化处理工艺，我们有效避免了长时间的活化过程。经过特殊处理的 LiVMoO ₅电极（STLVME）表现出优异的可逆比容量（~1100 mA hg ^-1）和倍率循环稳定性（容量保持率~100%）。此外，GITT和EIS还表明，与原始的LiVMoO ₅电极（LVME）相比，采用新的处理工艺导致了更小的内阻和更高的Li ^{+扩散系数，显着提高了倍率循环稳定性。}使用原位XRD 和非原位表征，我们说明了 LVME 和 STLVME 的锂存储机制。此外，还通过组装全电池探索了LVME和STLVME的实际应用潜力。由于有效地避免了长期活化过程，全电池表现出惊人的循环稳定性，表明STLVME可被认为是储能设备实际应用的有前途的潜在负极。
