Product Introduction
1.Background
Testing the crushing strength of battery material particles can be used to evaluate the pressure resistance of the material and guide the rolling process. Materials with high mechanical strength will have better subsequent cycle stability.
2. Testing Object
Lithium battery positive and negative electrode materials(Positive: polycrystalline ternary; lithium-rich material; Negative: silicon-based, hard carbon, etc.; solid electrolyte)
3. Test Particle Size
Single particle size: 5~50 um
4. Equipment Composition
Testing Program
1. Testing Method
Disperse the powder into the liguid., Add it dropwise to the glass slide. Locate the single particle under an optical microscope. Control the pressure head to press down at a constant speed. Collect the force and displacement curves during the particle compression process and calculate the mechanical properties of the single particle.
6) Comply with national standard GB/T 43091-2023″Powder Compressive strength Test Method”
Application Cases
1. Anode Material-Sic
1) Two silicon-carbon materials with different electrode compaction.
2) Comparison of crushing force distribution: A>B.
3) Analysis of stress-displacement curves: Sample A exhibits initialmicro-crackingfollowed by complete collapse, while sample B expe-riences direct structural collapse and fragmentation.
4) Comparison of Disintegration States: after fracturing, all three groups disintegrate into fine granular states.
Particle Compression Resistance and Powder Compaction
The compressive resistance of particle level C1 is stronger. Corresponding to the powder end, C1has a higher compression modulus than C2, with both maximum deformation and irreversible deformation smaller than C2.
Case 2: Three Different Carbon-Silicon Materials
SC-3 has weaker compressive strength of its particles, resulting in significantly larger maximum deformation and irreversible deformation when the powder is compressed compared to theother two materials.
2. Ternary Cathode Material-NCM811
