Abstract
Layered Cathodes
In article number 2500325, Li Wang, Aimin Du, Xiangming He, and co-workers introduce a novel two-step low-temperature oxidation and lithiation method for synthesizing high-performance nickel-rich layered oxide cathodes (LiNi0.9Co0.05Mn0.05O2). By preserving the MO6 framework through ambient oxidation and mild hydrothermal lithiation (≤90°C), the method achieves a discharge capacity of 239.3 mAh g−1 at 0.1C and an initial Coulombic efficiency of 95.76%, surpassing conventional high-temperature sintering. The approach minimizes structural defects, enhances crystallinity via post-annealing, and demonstrates versatility across Ni-rich systems. This breakthrough advances lithium-ion battery technology by optimizing energy density and mitigating irreversible capacity loss, offering scalable, defect-controlled cathode synthesis.
层状氢氧前驱体低温氧化制备高性能富镍层状阴极（Adv. Energy Mater. 27/2025）
层状阴极在2500325号文章中，王丽、杜爱民、何向明等介绍了一种新型的两步低温氧化-锂化法制备高性能富镍层状氧化物阴极（LiNi0.9Co0.05Mn0.05O2）。该方法通过环境氧化和轻度水热锂化（≤90℃）保存MO6骨架，在0.1C条件下放电容量达到239.3 mAh g−1，初始库仑效率达到95.76%，优于传统的高温烧结。该方法最大限度地减少了结构缺陷，通过后退火提高了结晶度，并展示了富镍系统的通用性。这一突破通过优化能量密度和减少不可逆容量损失，提供可扩展的、缺陷控制的阴极合成，推动了锂离子电池技术的发展。
