Close relationship between Ni content and inherent thermal instability of Ni‐rich cathode material has been widely investigated. However, the underlying cause of thermal instability of Ni‐rich cathode material involving Ni has not been fully studied. In article number 1902413, Won‐Sub Yoon and co‐workers propose the thermal expansion and oxygen vacancy as critical factors to affect the inherent thermal instability of Ni‐rich cathode materials. In the cover image, the thermal runaway of energy storage systems in industrial facilities is presented because it is closely related to the thermal instability of Ni‐rich cathode materials.

储能系统:跟踪热膨胀和氧气空缺对富镍层状阴极材料热稳定性的影响(Adv。Sci。12/2020)

镍含量与富镍正极材料固有的热不稳定性之间的密切关系已得到广泛研究。但是,尚未充分研究含Ni的富Ni阴极材料热不稳定性的根本原因。Won-Sub Yoon及其同事在编号为1902413的文章中提出,热膨胀和氧空位是影响富镍正极材料固有的热不稳定性的关键因素。在封面图像中,展示了工业设施中能量存储系统的热失控,因为它与富镍阴极材料的热不稳定性密切相关。
