高性价比长循环人造石墨负极材料GS-1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≥6.0、Dv50（15.5±2.0）、Dv90≤40.0、Dv99 ≤52.0四个粒度范围，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≥1.0g/cm³要求 ；通过比表面测试仪测出比表面积是否为（1.5±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检测比容量是否符合≥340.0mAh/g、首次效率是否满足≥93.0%标准数据。This dataset is compiled from detection data collected using multiple testing devices and analyzed against specified technical indicators. For example, the samples are divided into four particle size ranges (unit: μm): Dv10 ≥ 6.0, Dv50 (15.5 ± 2.0), Dv90 ≤ 40.0, and Dv99 ≤ 52.0. The particle size distribution is determined using a Malvern laser particle size analyzer. The tap density is tested with a Bettersize tap density tester to verify if it meets the requirement of ≥1.0 g/cm³. The specific surface area is measured by a specific surface area tester to confirm it is (1.5 ± 0.5) m²/g. The ash content is detected via a muffle furnace to check if it is ≤0.1%. The moisture content is measured by a moisture analyzer to confirm it is ≤0.1%. Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) is used to detect whether the magnetic substance content is ≤3.0 ppm, and confirm that the impurity element contents fall within the ranges of "Fe ≤ 50 ppm" and "Cu ≤ 10 ppm". Additionally, the specific capacity is tested via a half-cell/PVDF setup to verify it meets the standard of ≥340.0 mAh/g, and the first-cycle efficiency is confirmed to be ≥93.0%.
