Introduction

Interpretation of the National Standard of the People's Republic of China GB/T 37592—2019

1. Background and significance of the formulation of the standard

Carbonaceous mesophase spheres are an important carbon material, widely used in lithium-ion battery negative electrode materials, isostatic graphite and other carbon products. The formulation of GB/T 37592—2019 fills the gap in the domestic standard system in this field and provides a scientific basis for product quality control and testing.

2. Comparison of standard frameworks

Dimensions	GB/T 37592—2019	International similar standards	Industry status
Scope of application	Mesophase carbon microspheres for lithium-ion battery negative electrode materials, and other carbon products can be used for reference	Mainly used in high-performance lithium batteries	Some corporate standards are different
Technical indicators	Key performance indicators such as particle size, volatile matter, ash content, etc.	In line with domestic advanced levels	Some indicators need to be further optimized
Detection method	Based on GB/T 19077 particle size distribution laser diffraction method, etc.	Reference to international standards	Detection equipment needs to be further standardized

3. Technical requirements and performance index analysis

Main specifications of mesophase carbon microspheres: G10, G15, G25, G30, G40, respectively suitable for different application scenarios.

Key performance indicators:

Particle size D50 (μm): Strict range requirements according to different specifications
Volatile matter (%): ≤12.0
Ash content (%): ≤0.50
Toluene insoluble matter (%): ≥95.0
Quinoline insoluble matter (%): ≥95.0

4. Implementation suggestions and precautions

Implementation suggestions:

Enterprises should establish a sound quality management system to ensure that products meet standard requirements.
In the production process, strictly control the quality of raw materials and process parameters.
Strengthen detection capabilities and equip with advanced detection equipment such as laser particle size analyzers and element analyzers.

Notes:

Product packaging should comply with the relevant provisions of GB/T 37592-2019 to ensure safety during transportation and clarity of labels.
During storage, moisture and pollution should be avoided to ensure stable product quality.
