摘要:

钠离子电池凭借着丰富的钠资源、 低廉的物料成本以及良好的低温性能等优势, 在储能领域与锂离子电池兼容互补. 因此, 加速推进钠离子电池商业化可以降低锂资源供应风险, 确保新能源行业的长期健康发展. 由于钠离子的半径较大, 而负极材料作为其插层的宿主材料, 对相关的设计和发展要求则更高. 目前, 硬炭材料是公认的钠离子电池负极材料的理想选择之一, 也是最有可能实现大规模商业化生产的负极材料. 本文以钠离子电池商业化的瓶颈作为切入点, 对硬炭的材料特点、 储钠机理及功能化设计策略进行了综合评述. 最后, 对这一技术领域的未来发展和挑战进行了展望.

Abstract:

Sodium ion batteries(SIBs) have been regarded as the compatible and complementary to lithium ion batteries for energy storage due to abundant sodium resources, low cost and excellent low temperature performance. Therefore, accelerating the commercialization of SIBs can reduce the risk of lithium supply to ensure the long-term stable development of the new energy industry. As the host material for intercalation of large-radius sodium ions, the related design and development requirements of anode material are more demanding. Currently, hard carbon(HC) has been considered one of the most suitable anode materials for sodium ion batteries and large-scale commercialization. This paper reviews the bottleneck of high performance SIBs development, the materials characteristics, sodium storage mechanism and functionalized design strategies of hard carbon materials. Moreover, the advantages and disadvantages of various optimization strategies are discussed. Finally, future developments and challenges relating to ideal HCs are also proposed on the basis of recent progress.
