The casing of an OPzS battery plays a critical role in maintaining structural integrity and ensuring safe operation under various environmental and operational conditions. Below are the key design and material considerations.
- Material Selection:
OPzS battery casings are typically made from high-strength polypropylene (PP) or acrylonitrile butadiene styrene (ABS). These materials provide excellent chemical resistance, ensuring they can withstand contact with the sulfuric acid electrolyte and prevent corrosion. - Thermal Stability:
OPzS batteries are often deployed in environments with significant temperature fluctuations. The casing material must offer excellent thermal stability to minimize expansion or warping that could compromise the battery’s performance. - Mechanical Strength:
The casing must support the heavy weight of the lead plates and electrolyte while withstanding external mechanical shocks during transportation and installation. Reinforced designs or ribbed structures are often incorporated to enhance strength. - Sealing Integrity:
To prevent leakage of electrolyte and ensure safety, the casing must have high sealing precision. Ultrasonic or heat-sealing technologies are commonly used to secure tight connections.
