复合正极材料数据集

在固态锂硫电池中，正极中离子、电子传输均依靠活性物质与离子/电子导电添加剂的物理接触相关。为此我们通过表面修饰改善了导电助剂与活性物质界面的电荷传输，提高正极的放电比容量和循环稳定性。本数据集主要包含复合正极长循环数据，正极循环1000圈容量保持率高于90%.

In solid-state lithium-sulfur batteries, the transport of both ions and electrons in the cathode relies on the physical contact between active materials and ionic/electronic conductive additives. To this end, we improved the charge transport at the interface between conductive additives and active materials via surface modification, thereby enhancing the discharge specific capacity and cycling stability of the cathode. This dataset mainly contains long-cycle performance data of composite cathodes, with the capacity retention rate exceeding 90% after 1000 charge-discharge cycles.
