The emergency of high-power electrical appliances has put forward higher requirements for the power density of lithium-ion batteries. Vanadium oxides with large theoretical capacities and high operating voltages are considered as prospective alternatives for the cathode of a new generation of lithium-ion batteries. However, the poor rate and cycling performance caused by the sluggish electrons/lithium transportation, irreversible phase changes, vanadium dissolution and large volume changes during the repeated lithium intercalation/deintercalation hinder their commercial development. Several optimizing routes have been carried out and extensively explored to address these problems. Taking V₂O₅, VO₂(B), V₆O₁₃, and V₂O₃ as examples, this article reviewed their crystal structures and lithium storage reactions. Besides, recent progress in modification methods for the electrochemical insufficiencies of vanadium oxides, including nanostructure, heterogeneous atom doping, composite and self-supported electrodes has been systematically summarized and finally, the challenges for the industrialization of vanadium oxide cathodes and their development opportunities are proposed.

大功率电器的紧急状况对锂离子电池的功率密度提出了更高的要求。具有大理论容量和高工作电压的氧化钒被认为是新一代锂离子电池正极的潜在替代品。然而，在重复的锂嵌入/脱嵌过程中，由于电子/锂传输缓慢，不可逆的相变，钒溶解和大量的体积变化而导致的不良速率和循环性能阻碍了它们的商业发展。为了解决这些问题，已经进行了几种优化途径，并进行了广泛探索。取V ₂ O ₅，VO ₂（B），V ₆ O ₁₃，以V ₂ O ₃为例，本文综述了它们的晶体结构和锂存储反应。此外，系统地总结了钒氧化物电化学不足的改性方法的最新进展，包括纳米结构，异质原子掺杂，复合电极和自支撑电极，最后提出了钒氧化物阴极工业化的挑战及其发展机遇。 。
