制造具有高能量密度和可循环性的可持续钠离子电池需要独特的定制技术，并密切关注经济和环境因素。在这项工作中，我们总结了钠离子电池中最重要的设计指标，重点是阴极材料，并概述了基于未来技术性能评估通用指标的透明数据报告方法。钠离子电池被认为是锂基电池技术最有前途的替代品之一。尽管该领域的研究越来越多，但由于缺乏具有长循环寿命的高能量密度正极材料，该技术的实施实际上受到了阻碍。从这个角度来看，我们首先概述了随着时间的推移，钠离子电池（NIB）系统发展的里程碑。接下来，我们将讨论NIB阴极材料中使用的关键元素提取的关键指标，这可能会在不久的将来影响供应链。最后，在寻找下一代nib最有前途的正极材料的过程中，我们对过去10年295多份报告的设计和测试的主要发现进行了广泛的分析，表明层状氧化物、普鲁士蓝类似物（PBAs）和聚阴离子是正极材料的主要候选材料。对目前所有可用的正极材料的能量密度和容量保持率进行了深入的比较。从这个角度来看，我们也强调了基于现有数据集的大数据分析对可持续材料设计的重要性。从这个角度提供的见解，以及更透明的数据报告方法和NIB性能评估的通用指标的实施，可以帮助加速NIB领域未来的阴极材料设计。图形抽象
Manufacturing sustainable sodium ion batteries with high energy density and cyclability requires a uniquely tailored technology and a close attention to the economical and environmental factors. In this work, we summarized the most important design metrics in sodium ion batteries with the emphasis on cathode materials and outlined a transparent data reporting approach based on common metrics for performance evaluation of future technologies. Sodium-ion batteries are considered as one of the most promising alternatives to lithium-based battery technologies. Despite the growing research in this field, the implementation of this technology has been practically hindered due to a lack of high energy density cathode materials with a long cycle-life. In this perspective, we first provide an overview of the milestones in the development of Na-ion battery (NIB) systems over time. Next, we discuss critical metrics in extraction of key elements used in NIB cathode materials which may impact the supply chain in near future. Finally, in the quest of most promising cathode materials for the next generation of NIBs, we overlay an extensive perspective on the main findings in design and test of more than 295 reports in the past 10 years, exhibiting that layered oxides, Prussian blue analogs (PBAs) and polyanions are leading candidates for cathode materials. An in-depth comparison of energy density and capacity retention of all the currently available cathode materials is also provided. In this perspective, we also highlight the importance of large data analysis for sustainable material design based on available datasets. The insights provided in this perspective, along with a more transparent data reporting approach and an implementation of common metrics for performance evaluation of NIBs can help accelerate future cathode materials design in the NIB field.
