锂正极上不稳定的固体电解质界面(SEI)是锂电池面临的主要性能挑战，即库仑效率(CE)不足和循环寿命不足。虽然我们知道SEI参与了老化过程，但通过追踪到特定的SEI相来准确地确定化学来源在实验上一直是具有挑战性的。在这里，我们形成了单相、薄(
The unstable solid-electrolyte interphase (SEI) on Li anodes is the origin of major performance challenges in Li batteries, namely, insufficient Coulombic efficiency (CE) and cycle life. While it is known that the SEI participates in aging processes, pinpointing the chemical origins by tracing them to specific SEI phases has been experimentally challenging. Here, we formed single-phase, thin (
