摘要

锂金属电池（lmb）作为高能量密度存储设备显示出巨大的潜力。然而，它们的实际应用受到锂枝晶形成、易燃性和商业碳酸盐电解质有限的工作温度范围等挑战的阻碍。为了解决这一问题，我们开发了一种以离子液体为溶剂的局部高浓度电解质（LHCE）。LHCE具有不可燃性，工作温度范围宽（- 30 ~ 70℃），形成刚性的高离子导电性固体电解质界面（SEI），显著提高了lhbs的循环稳定性。

Designing ionic liquid electrolytes for a rigid and Li+-conductive solid electrolyte interface in high performance lithium metal batteries

Lithium metal batteries (LMBs) demonstrate significant potential as high-energy-density storage devices. However, their practical application is hindered by challenges such as lithium dendrite formation, flammability, and the limited operating temperature range of commercial carbonate electrolytes. To address the issue, we developed a localized highly concentrated electrolyte (LHCE) using an ionic liquid as the solvent. The LHCE exhibits non-flammability, a wide operating temperature range (−30 to 70 °C), and forms a rigid, highly ion-conductive solid electrolyte interphase (SEI), which significantly enhances the cycling stability of LMBs.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
