Abstract

The Cover Feature shows how direct recycling of spent LiNi_xMn_yCo_zO₂ (NMC) cathode materials is achieved by using reciprocal ternary molten salts. The molten-salt flux facilitates transition metal diffusion and exchange among various NMC particles—such as nickel-lean (e.g., NMC 111, purple dotted particles) and nickel-rich compositions (e.g., NMC 811, orange dotted particles). This compositional reconfiguration leads to improved cycling stability compared to pristine NMCs in both half-cell and full-cell tests. More information can be found in the Research Article by T. Wang, S. Dai and co-workers (DOI: 10.1002/cssc.202500571).

封面特色：相互作用的三元熔盐可以直接升级回收废锂-镍-锰-钴氧化物（NMC）混合物，以制造NMC 622 （ChemSusChem 14/2025）

Cover Feature展示了如何通过使用互反三元熔盐来实现废LiNixMnyCozO2 （NMC）阴极材料的直接回收。熔盐助熔剂促进过渡金属在各种NMC颗粒之间的扩散和交换，例如贫镍成分（例如，NMC 111，紫色点状颗粒）和富镍成分（例如，NMC 811，橙色点状颗粒）。在半电池和全电池测试中，与原始nmc相比，这种成分的重新配置提高了循环稳定性。更多信息请参见王涛、戴思等人的研究文章（DOI: 10.1002/cssc.202500571）。
