论文摘要
缩写是一个集体术语，用于电解质衰减的电荷相关性比Debye长度慢。异常强调是指不能单独归因于空间相互作用的现象学。浓缩电解质和离子流体的实验报告了异常的隔离，到目前为止，在模拟中尚未观察到。我们提出了分子动力学仿真结果，表现出异常的下划线，可以连接到簇形成。说明离子配对的理论证实了这一趋势。我们的结果挑战了对密集电解质的经典理解，影响了用于储能和转换技术的技术。
Underscreening is a collective term for charge correlations in electrolytes decaying slower than the Debye length. Anomalous underscreening refers to phenomenology that cannot be attributed alone to steric interactions. Experiments with concentrated electrolytes and ionic fluids report anomalous underscreening, which so far has not been observed in simulation. We present Molecular Dynamics simulation results exhibiting anomalous underscreening that can be connected to cluster formation. A theory that accounts for ion pairing confirms the trend. Our results challenge the classic understanding of dense electrolytes impacting the design of technologies for energy storage and conversion.
