In the highly precise world of lithium battery manufacturing, every step is crucial to the final performance and safety of the product. Among these steps, the purity of water, a seemingly basic aspect, is the "lifeline" that determines the quality of the battery. The lithium battery ultra-pure water equipment is the core equipment that ensures this lifeline. As a leading provider of water treatment solutions in the industry, Bai Huipu Environmental Protection will deeply analyze the irreplaceable importance of ultra-pure water for lithium battery production.
1. Why is ultra-pure water necessary for lithium battery production?
The ions, particles, microorganisms and dissolved gases present in ordinary water are lethal "pollutants" for lithium batteries. They can:
1. Affects electrode coating: Results in uneven paste distribution, formation of bubbles and pinholes, which seriously affects the consistency of the battery.
2. Triggering internal short circuit: During the charging and discharging process, metal ions will form dendrites that pierce the separator, causing a short circuit and even leading to fire and explosion.
3. Accelerated self-discharge: Impurity ions will participate in secondary reactions, accelerating the degradation of battery capacity and shortening its service life.
4. Reduction of electrolyte performance: Water reacts with the lithium salts in the electrolyte, generating harmful substances such as HF, which corrodes the interior of the battery.
Therefore, the water used in lithium battery production must meet extremely high purity standards. The resistivity is usually required to be ≥ 18 MΩ·cm (at 25℃), and there are also extremely strict controls over the levels of total organic carbon (TOC), particles, and microorganisms.
II. The core technology of Baihuipu lithium battery ultra-pure water equipment
Baihuipu Environmental Protection, leveraging its long-term technological accumulation, has developed lithium battery ultra-pure water equipment that integrates a series of advanced water treatment technologies to ensure stable and reliable water quality of the produced water:
Pre-treatment system: Utilizes multi-media filters, activated carbon filters, etc., to effectively remove suspended solids, colloids, residual chlorine and organic substances from the raw water, providing protection for the subsequent precision equipment.
Reverse osmosis system: As the core unit for desalination, it can remove over 99% of ions, organic substances and microorganisms from water, and is the first crucial barrier for purifying water.
EDI desalination system: This is the key advantage of Baihuipu equipment. EDI does not require acid-base regeneration and can continuously and stably produce high-purity water with a resistivity of up to 15-18 MΩ·cm, achieving green and environmentally friendly deep desalination.
Polishing mixed bed system: As the final water quality guarantee, it can steadily increase the resistivity of the produced water to over 18.25 MΩ·cm, meeting the most stringent requirements for lithium battery production.
