The standard "GB/T 44330-2024 Determination of powder compaction density of anode materials for lithium-ion batteries" details the determination method of powder compaction density of anode materials for lithium-ion batteries. The standard includes the basic principle of testing, required reagents and equipment, sample requirements, experimental procedures, data processing methods, precision requirements and format of test reports. Powder compaction density refers to the ratio of the mass of powder material to the volume occupied by it under a certain pressure, which is one of the important indicators for evaluating the performance of lithium-ion batteries. The implementation of this standard aims to improve the quality control and conformity of lithium-ion battery anode materials, ensure the safety and performance Stability of batteries, and is suitable for research and production in related fields.
