Lithium-Ion Battery Tests Experimental Protection

In the context of global energy transition and environmental protection, the rapid expansion of the electric vehicle and mobile device markets presents unprecedented opportunities and challenges for lithium-ion batteries as a key energy storage technology. However, R&D and QC tests inevitably involve the use of chemicals and hazardous substances, posing safety and environmental challenges in laboratory settings.

Experiment 1: Measurement of Initial Coulombic Efficiency and Initial Discharge Specific Capacity

Procedure : Accurately measure active materials, NMP (N-Methyl-2-pyrrolidone), binder, etc. → Mix into a homogeneous slurry → Apply onto current collector foil (copper for anode, aluminum for cathode) → Dry in a vacuum oven → Assemble battery cells in a glove box.
Safety Risks:
–NMP: Respiratory irritant, long-term exposure may affect fertility, fetal development, and increase cancer risk.
–Binders and Conductive Agents: Irritants, pose inhalation risks.
–Inhalation of Particulates: Airborne fine particulates during mixing and coating.

Experiment 2: Particle Size Inspection of Cathode and Anode Materials (ISO 13320; GB/T 19077-2016)

Procedure: Sample preparation → Disperse in liquid medium (e.g., water, alcohol) → Stir into a paste → Test.
Safety Risks:
–Powder Inhalation: Airborne fine particles during sample preparation and dispersion.
–Alcohol Exposure: Hazardous if inhaled or in contact with skin/eyes.

Experiment 3: Testing Other Indicators (e.g., Slurry Solid Content, Viscosity, Fineness, Material Moisture, Solvent Purity)

Procedure:
Direct measurement or pre-treatment (transfer, dilution) before testing.
Safety Risks:
–NMP: Respiratory irritant, long-term exposure may affect fertility, and fetal development, and increase cancer risk.
–Binders and Conductive Agents: Irritants, pose inhalation risks.
–Inhalation of Particulates: Airborne fine particulates during mixing and coating.
