High precision powder compression performance testing instrument for battery material compaction density tester

Description :

1、 Function Description

The FT-100H-5T powder automatic compaction density meter is equipped with a 7-inch touch display screen and a dual control mode of PC software, relying on the load unit control system to collect real-time stress change data. The device supports custom setting of parameters such as test pressure and holding time, and can directly read the thickness value of the sample. It is compatible with both automatic and manual operation modes, and can adapt to different test scenario requirements. The equipment can be used in conjunction with vacuum molds, and the accompanying PC software can fully analyze stress, density, time, displacement data during the testing process and generate visual graphs. It can assist in the research and development, quality control, and process optimization of new energy battery materials, establish standardized data models for the industry, and support bilingual switching between Chinese and English.

2、 Working principle

The equipment compresses the powder sample through external force, causing displacement and deformation of the powder particles during the compression process, filling the gaps between particles and effectively reducing the overall porosity of the material. As the contact area between particles gradually increases, the interatomic forces and the mechanical wedging effect of particles continue to strengthen, ultimately forming a compact structure with dense structure and stable performance. This accurately detects the density parameters of powder materials after compaction, which is in line with the actual production rolling conditions.

3、 Implement reference standards

The equipment strictly follows multiple national and industry standards and is suitable for the testing needs of lithium battery powder materials. The standards cover:

GB/T 30835-2014 Carbon composite lithium iron phosphate cathode material for lithium-ion batteries

GB/T 30836-2014 Lithium titanate and its carbon composite negative electrode materials for lithium-ion batteries

GB/T 24533-2019 Graphite based Negative Electrode Materials for Lithium ion Batteries

GB/T 44330-2024 Determination of Powder Compaction Density of Positive Electrode Materials for Lithium ion Batteries

GB/T 41232.2-2021/IEC/TS 62607-4-2:2016 Nanomanufacturing Key Control Characteristics Nano Energy Storage Part 2: Density Testing of Nano Positive Electrode Materials

It can also be applied to the compaction density detection of various powders and granular materials with the same characteristics, with strong universality and wide applicability.
