高性价比长循环人造石墨负极材料GS-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≥6.5、Dv50（16.5±2.5）、Dv90≤45.0、Dv99 ≤58.0四个粒度范围，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≥0.90g/cm³要求 ；通过比表面测试仪测出比表面积是否为≤2.0m2/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≥349.0mAh/g、首次效率是否满足≥90.0%标准数据。This dataset is developed based on test data collected from multiple detection devices and analyzed in accordance with technical specifications. For example, samples are categorized into four particle size ranges based on particle size (unit: μm): Dv10≥6.5, Dv50 (16.5±2.5), Dv90≤45.0, Dv99 ≤58.0, and the particle size distribution is determined using a Malvern Laser Particle Size Analyzer. The tap density is tested with a Baite Tap Density Meter to confirm whether it meets the requirement of ≥0.90 g/cm³; the specific surface area is measured by a Specific Surface Area Analyzer to verify if it is ≤2.0 m²/g; the ash content is detected via a Muffle Furnace to check whether it is ≤0.1%; the moisture content is tested with a Moisture Analyzer to confirm if it is ≤0.1%; magnetic substances are detected to be ≤3.0 ppm via ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometer), and the contents of impurity elements are verified to fall within the ranges of "Fe≤50 ppm" and "Cu≤10 ppm". The specific capacity is tested via a half-cell/PVDF system to meet the standard of ≥349.0 mAh/g, and the first-cycle efficiency is validated to satisfy the requirement of ≥90.0%.
