2015年3月10日 · The model is zero-dimensional and defines the accumulated charge of lithium, Q SEI (C), lost in the battery due to side reactions forming the SEI layer on the graphite particles. The charge balance is defined as

2021年6月7日 · 金属负极与电解液之间通过化学和电化学反应形成的固体电解质界面相（SEI）被认为是决定电池长期稳定性的关键因素。 近期美国康奈尔大学赵庆博士和Lynden Archer教授等在能源顶级期刊Joule 上发文，系统了分析目前SEI的研究成果，指出了未来SEI的设计思路。 固体电解质界面相（SEI）是在所有电化学电池的显性或隐性界面上由电化学和化学反应结合而形成的化学上独特的物质相。 在过去十年中，这种界面相材料的结构、化学和热力学被广泛认为在二 …

2023年6月12日 · The improved homogeneity and mechanical stability of bilayer/P‒F SEI leads to highly reversible Li plating/stripping with mitigated SEI reconstruction and prolonged lifespan of Li metal coin ...

2020年8月7日 · In this article, a continuum model is developed that consistently captures the influence of open‐circuit potential, current direction, current magnitude, and cycle number on the growth of the SEI. The model is based on the formation and diffusion of neutral lithium atoms, which carry electrons through the SEI.

2021年5月19日 · Artificial SEI (ASEI) is a second attractive solution for overcoming shortcomings of intrinsically formed interphases. Because the SEI is created outside an electrochemical cell, the properties and composition of the interphase can be precisely tuned, due to many degrees of freedom, to control the morphology of the electrodeposited metal.

2024年6月8日 · 天津大学Nanoyang团队的杨全红教授和吴士超研究员首次定义了全新的SEI设计标准，即SEI应同时具备较高弹性和粘附性（re-ad-SEI），将改性策略由之前的刚性转变为粘弹，有效地保护了高容量、大变形的负极材料，破解了高膨胀负极的稳定性难题。

以 双 (氟磺酰基)亚胺锂 （Lithium bis (fluorosulfonyl)imide, LiFSI）为基础的液体电解液在实现高库仑效率（coulombic efficiency）和长循环寿命的下一代 锂金属电池 （Li-metal batteries）中展现出巨大的潜力。 然而，阴离子在 固态电解质界面 （solid–electrolyte interphase, SEI）形成过程中的作用仍不明确。 斯坦福大学鲍哲南院士、崔屹院士 等人结合 电化学分析 和 X射线光电子能谱 测量和 计算模拟，提出了电解质分解的反应途径，并将界面相组分的溶解度与钝化效果联系起来。

本文提出了一种简单而高效的金属氯化物水解策略，通过快速地在Mg负极表面构筑一层致密的人工SEI，避免电解液的分解以及诱导Mg均匀的沉积/剥离提高镁负极的循环寿命。
