界面特性调控及电荷传输行为研究过程数据集

离子、电子分别通过电解质和导电碳材料传输到正极活性物质，其间必定穿越由活性物质/导电材料形成的物理接触界面，界面的离子、电子传输特性对正极反应动力学有重要的影响。为了提高固态锂硫电池复合正极放电比容量和循环稳定性，我们在正极颗粒表面包覆了电解质，将硫化物电解质与正极颗粒间点对点的接触改为点对面的接触，改善界面电荷传输动力学。本数据是界面改善研究过程中所产生的数据。Ions and electrons are transported to the cathode active material via the electrolyte and conductive carbon material respectively, and must necessarily traverse the physically contacted interface formed by the active material/conductive material. The ion and electron transport characteristics of this interface exert a significant impact on the cathode reaction kinetics. To enhance the specific discharge capacity and cycling stability of the composite cathode for solid-state lithium-sulfur batteries, we encapsulated the electrolyte on the surfaces of cathode particles, changing the point-to-point contact between the sulfide electrolyte and cathode particles into point-to-area contact to improve the interfacial charge transport kinetics. This dataset was generated during the research on interfacial property improvement.
