超长循环人造石墨负极材料GLD-2产品型号技术标准数据

基于多种检测设备的检测数据，根据技术指标分析而成。如，按照粒度（单位：μm ）划分为Dv10≥3.5、Dv50（11.0±2.0）、Dv90≤35.0、Dv99 ≤55.0四个粒度范围，通过马尔文激光粒度仪检测确定粒度分布；通过百特振实密度仪检测振实密度是否符合≥1.05g/cm³要求 ；通过比表面测试仪测出比表面积是否为（1.6±0.5）m2/g ；通过马弗炉检测出灰分是否≤0.1%；通过水分测定仪检测出水分是否≤0.1%；通过ICP-OES 电感耦合等离子体发射光谱仪检测磁性物质是否≤3.0ppm 和确认杂质元素含量在以下元素含量划分“Fe≤50ppm ”“Cu≤10ppm” 的范围。通过半电池/PVDF Half cell test/PVDF检测比容量是否符合≥340.0mAh/g、首次效率是否满足≥91.0%标准数据。

This dataset is compiled based on detection data from multiple testing devices, with analysis conducted per technical specifications. For example, the particle size distribution is divided into four ranges based on particle size (unit: μm): Dv10≥3.5, Dv50 (11.0±2.0), Dv90≤35.0, and Dv99 ≤55.0, which is determined using a Malvern laser particle size analyzer. The tap density is tested via a Bettersize tap density tester to verify whether it meets the requirement of ≥1.05 g/cm³. The specific surface area is measured by a specific surface area analyzer to confirm that it is (1.6±0.5) m²/g. The ash content is detected using a muffle furnace to check if it is ≤0.1%. The moisture content is measured by a moisture analyzer to ensure it is ≤0.1%. Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) is employed to detect whether the magnetic substance content is ≤3.0 ppm, and to confirm that the contents of impurity elements fall within the ranges of "Fe≤50 ppm" and "Cu≤10 ppm". Additionally, the specific capacity and first-cycle efficiency are tested via the half-cell/PVDF Half cell test/PVDF assay, to verify whether the specific capacity meets the standard of ≥340.0 mAh/g and the first-cycle efficiency satisfies the standard of ≥91.0%.
