| 中文摘要: |
| 锂离子电池因其良好的循环寿命以及较高的能量密度广泛应用于各种电子设备中,但是由于地壳中锂资源有限且存在安全性问题,锂离子电池的大规模应用被限制。所以迫切需要寻找一种成本低且安全性高的储能设备。钠离子电池(SIB)是目前锂离子电池最有希望的补充或替代设备。虽然目前钠资源较为丰富,钠离子电池安全性较好,但是钠离子电池也存在很多问题,其能量密度与循环稳定性远不能满足市场要求。其中正极材料在很大程度上限制了电池的成本和性能。本文从介绍了钠离子电池正极材料的分类并着重介绍了层状过渡金属氧化物正极材料的结构、合成以及其所面临的挑战和改性策略。以期为开发具有更加优异的化学性能,更加符合市场需求,能够大规模生产和应用的实用SIB提供思路。 |

| Lithium-ion batteries are widely used in various electronic devices due to their good cycle life and high energy density, but the large-scale application of lithium-ion batteries is limited due to the limited lithium resources in the earth"s crust and safety issues. Therefore, there is an urgent need to find an energy storage device with low cost and high safety. Sodium-ion batteries (SIBs) are the most promising complementary or alternative devices to lithium-ion batteries. Although sodium resources are relatively abundant and the safety of sodium-ion batteries is good, there are many problems with sodium-ion batteries, and their energy density and cycle stability are far from meeting the market requirements. Among them, the cathode material limits the cost and performance of the battery to a large extent. This paper introduces the classification of cathode materials for sodium-ion batteries and focuses on the structure and synthesis of layered transition metal oxide cathode materials, as well as their challenges and modification strategies. It is intended to provide ideas for the development of practical SIBs with more excellent chemical properties, more in line with the market demand, and capable of large-scale production and application. |
