Moisture-Proof Protection in the Battery Productio more
Moisture control is one of the most critical factors in battery manufacturing, especially for lithium-ion batteries. Even small amounts of moisture can react with electrolytes, produce harmful gases, reduce battery performance, shorten service life, and cause potential safety risks.
To ensure high product quality and stability, strict moisture-proof measures are implemented throughout the entire production process:

  • Raw material storage: All electrode materials, separators, electrolytes and components are stored in low-humidity dry rooms and sealed environments.

  • Electrode production: Humidity is strictly controlled during coating, rolling and slitting to prevent moisture absorption.

  • Cell assembly: Winding, lamination and casing are completed in ultra-dry workshops with precise dew point control.

  • Pre-injection baking: Cells are fully baked under high temperature and vacuum to remove residual moisture.

  • Electrolyte injection & sealing: The whole process is carried out in a dry, isolated environment to avoid moisture re-entry.

  • Finishing & packaging: Finished batteries are packaged with moisture-proof materials to maintain long-term stability.


Battery cells and modules are highly sensitive to moisture and humidity. Improper storage can lead to performance degradation, internal corrosion, electrolyte decomposition, swelling, and shortened service life. Therefore, professional moisture‑proof storage conditions and management are essential.
  • Controlled environment storage
    Store cells and modules in a dry, ventilated, and constant‑temperature warehouse. Maintain appropriate temperature and low relative humidity to avoid condensation and moisture absorption.
  • Sealed and moisture‑proof packaging
    Use sealed bags, desiccants, and vacuum or nitrogen‑filled packaging to isolate external humidity. Replace desiccants regularly to ensure long‑term effectiveness.
  • Stacking and handling management
    Avoid direct contact with the ground or damp walls. Use moisture‑proof pallets and control stacking height to prevent damage to packaging and moisture intrusion.
  • Environment monitoring
    Install humidity and temperature monitoring equipment to track environmental changes in real time. Adjust dehumidification or ventilation accordingly to maintain stable storage conditions.
  • Inventory turnover control
    Implement first‑in, first‑out (FIFO) inventory management to reduce long‑term storage risks and ensure cells and modules remain in optimal condition before assembly or delivery.
Standardized moisture‑proof storage effectively maintains product performance, safety, and reliability, ensuring stable quality when cells and modules are put into use.



3. Moisture-Proof Protection in the Battery Transportation Process

1. Moisture-Proof Protection in the Battery Production Process

Moisture control is critical in battery manufacturing. Even trace moisture may react with electrolytes, causing gas generation, performance degradation, swelling, shortened service life, and potential safety hazards. We implement strict moisture-proof measures throughout production:

  • Raw materials are stored in low-humidity dry rooms to avoid moisture absorption.

  • Humidity is tightly controlled during electrode coating, rolling and slitting.

  • Cell assembly is completed in an ultra-dry workshop with precise dew point management.

  • Cells undergo high-temperature vacuum baking before electrolyte injection to remove residual moisture.

  • Electrolyte injection and sealing are carried out in a dry, isolated environment.

  • Finished batteries use professional moisture-proof packaging for long-term protection.

2. Moisture-Proof Storage for Battery Cells and Modules

Battery cells and modules are highly sensitive to moisture. Improper storage can lead to performance loss, corrosion and swelling. Our standardized moisture-proof storage system includes:

  • Constant low-humidity and well-ventilated storage environment with real-time temperature and humidity monitoring.

  • Sealed packaging with desiccants, vacuum or nitrogen filling to isolate external humidity.

  • Moisture-proof pallets and standardized stacking to avoid contact with damp ground or walls.

  • FIFO inventory management to reduce long-term storage risks and ensure product stability.

Through full-process moisture-proof protection, we effectively guarantee the safety, performance and service life of batteries.
