| 开发新型锂离子电池负极材料是进一步提升锂离子电池综合电化学性能的重要方向。基于转化反应机制的氢化物基锂离子电池负极材料，具有较高的理论比容量和良好的电化学反应动力学性能，受到了广泛的关注。然而，氢化物基负极材料在电池中服役时，存在充放电性能差、循环稳定性不足等问题。研究表明，这些问题与氢化物的放电产物分相、氢化物与电解质会发生副反应等因素密切相关。综述了氢化物基锂离子电池负极材料的研究进展，包括典型氢化物的结构特点和电化学性能，并探讨了进一步提高氢化物基锂离子电池负极材料性能的途径，如结构优化和纳米限域等。 |

| Developing novel anode materials for lithium-ion batteries is an important direction for further improving the overall electrochemical performance of lithium-ion batteries. The hydride-based lithium-ion battery anode materials based on a conversion reaction mechanism have high theoretical specific capacity and good electrochemical reaction kinetic performance and have caused widespread attention. However, hydride-based anode materials have problems such as poor charge-discharge performance and insufficient cycling stability when used in batteries. Studies have shown that these problems are closely related to some factors such as phase separation of discharge products from hydrides and side reactions between hydrides and electrolytes. The recent research progress on hydride-based anode materials was summarized, including the structural characteristics and electrochemical performance of typical hydrides, and the ways to further improve the performance of hydride-based anode materials were explored, such as structural optimization and nanoconfinement. |
