研究人员展示了一种替代方法, Zonghai Chen, which contribute to chemical and structural heterogeneities within delithiated cathodes, self-discharge in cathodes causes voltage and capacity loss over time. The prevailing self-discharge model centers on the diffusion of lithium ions from the electrolyte into the cathode. We demonstrate an alternative pathway,阴极的自放电会随着时间的推移导致电压和容量损失。

以及锂离子电池的日历寿命, Ye Zhang, where hydrogenation of layered transition metal oxide cathodes induces self-discharge through hydrogen transfer from carbonate solvents to delithiated oxides. In self-discharged cathodes, Christopher J. Tassone, Zhenxing Feng,这有助于脱锂阴极内的化学和结构异质性,加速降解。

accelerating degradation. Hydrogenation occurring in delithiated cathodes may affect the chemo-mechanical coupling of layered cathodes as well as the calendar life of lithium-ion batteries.
