Research interest in Na-ion batteries has increased rapidly because of the environmental friendliness of sodium compared to lithium. Throughout this Perspective paper, we report and review recent scientific advances in the field of negative electrode materials used for Na-ion batteries. This paper sheds light on negative electrode materials for Na-ion batteries: carbonaceous materials, oxides/phosphates (as sodium insertion materials), sodium alloy/compounds and so on. These electrode materials have different reaction mechanisms for electrochemical sodiation/desodiation processes. Moreover, not only sodiation-active materials but also binders, current collectors, electrolytes and electrode/electrolyte interphase and its stabilization are essential for long cycle life Na-ion batteries. This paper also addresses the prospect of Na-ion batteries as low-cost and long-life batteries with relatively high-energy density as their potential competitive edge over the commercialized Li-ion batteries.
由于钠相对于锂具有环境友好性，对钠离子电池的研究兴趣迅速增加。在这篇综述文章中，我们报告并回顾了钠离子电池负极材料领域的最新科学进展。本文阐述了钠离子电池的负极材料：碳质材料、氧化物/磷酸盐（作为钠插入材料）、钠合金/化合物等。这些电极材料在电化学嵌钠/脱钠过程中具有不同的反应机制。此外，不仅是嵌钠活性材料，还有粘合剂、集流体、电解质以及电极/电解质界面及其稳定性，对于长循环寿命的钠离子电池都是必不可少的。本文还探讨了钠离子电池作为低成本、长寿命且具有相对较高能量密度的电池的前景，这是它们相对于商业化锂离子电池的潜在竞争优势。
