In lithium-ion batteries, the electrochemical instability of the electrolyte and its ensuing reactive decomposition proceeds at the anode surface within the Helmholtz double layer resulting in a …

Aug 10, 2021 · 然而，这些技术缺乏空间分辨率来解析sei中纳米晶体的原子晶格。高分辨透射电镜(hrtem)能够探测到sei中无机层的详细原子结构。然而，在传统的tem中，sei很快被电子所破 …

The solid electrolyte interphase (SEI) plays a critical role in determining the cycling stability of the graphite anode. However, viewing the SEI in batteries remains challenging due to its …

May 25, 2024 · Here, the authors present an YF3/PMMA composite layer to achieve high-performance LMBs via the synergetic regulation of SEI mechanics and Li crystallography.

Apr 13, 2023 · Using a proper dose rate of Cryo-TEM can provide the fine atomic structure of a dual-layered inorganic-rich SEI and explain the difference with the SEI layer in the …

Here, we unveiled the atomic structures and phase distribution of the fragile solid electrolyte interphase (SEI) on graphite using ultra-low-dosage and aberration-corrected cryo …

Jun 23, 2015 · Transmission electron microscopy (TEM) experiment is performed to present the SEI layer structures. The experiments reduce the complexity of the model development and …

Cryo-TEM shows that the outermost SEI will collapse once the Li deposits were stripped in the ether electrolyte (Figure 3c). In subsequent Li deposition, there will form a new SEI and the …

Dec 12, 2023 · 本文中，作者利用一种原位偏置透射电子显微镜（tem）方法来直接测量在铜（cu）和锂（li）衬底上生长的sei层的电学性质，揭示了sei在电流（i）-电压（v）关系、微分 …

近日，南方科技大学谷猛教授，邓永红副教授，美国麻省理工学院李巨教授报道了利用超低剂量和像差校正的冷冻电镜（cryo-tem）系统地研究了石墨上的sei，使用了碳酸丙烯酯c 4 h 6 o 3 …
