高能量密度人造复合石墨负极材料M01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≥4.0、Dv50（13.5±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≥0.90g/cm³要求 ；通过比表面测试仪测出比表面积是否≤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 Half cell test/PVDF检测比容量是否符合≥350.0mAh/g、首次效率是否满足≥90.0%标准数据。

This dataset is developed based on detection data from multiple testing devices, with analysis performed according to technical indicators. For example, the particle size distribution is divided into four ranges based on particle size (unit: μm): Dv10 ≥ 4.0, Dv50 (13.5 ± 2.0), Dv90 ≤ 35.0, and Dv99 ≤ 55.0, which is determined via a Malvern laser particle size analyzer. The tap density is tested with a Bettersize tap density tester to verify whether it meets the requirement of ≥ 0.90 g/cm³. The specific surface area is measured by a specific surface area analyzer to confirm whether it is ≤ 2.0 m²/g. Ash content is detected via a muffle furnace to check if it is ≤ 0.1%. Moisture content is tested by a moisture analyzer to ensure it is ≤ 0.1%. Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) is utilized 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". The specific capacity and first-cycle efficiency are evaluated via a half-cell test (PVDF Half cell test/PVDF), where the specific capacity must meet the standard of ≥ 350.0 mAh/g and the first-cycle efficiency should satisfy the requirement of ≥ 90.0%.
