Application
In the field of new energy and energy storage, lead-acid batteries remain the core choice for many scenarios due to their stable performance and mature technology. As a key auxiliary material for lead-acid battery production, the quality of battery-specific barium sulfate directly determines the battery's capacity, endurance and service life.
With years of experience in the industry, the battery-specific precipitated barium sulfate we launched adheres to strict standards that far exceed the national standard GB/T 38279-2019, laying a solid foundation for lead-acid battery production and serving as an optimal partner for creating high-end, durable battery products.

The high-purity barium sulfate base can effectively increase the specific gravity of the storage battery, greatly increase the battery capacity and optimize the discharge efficiency; the ultra-low iron content fundamentally avoids the corrosion of the battery plate by impurities, reduces the risk of self-discharge, and makes the battery last longer.
✅Core Characteristics, Suitable for Full-Scenario Production
-
Excellent Dispersion: The powder is fine and uniform, with a precisely controlled particle size of 0.75~0.95μm. It can disperse quickly in lead paste, improve the utilization rate of active substances on the plate, and is suitable for various lead-acid battery production processes.
-
Stable Chemical Properties: It is a white powder with a relative density of 4.50. It is insoluble in water, ethanol and acids, but only soluble in hot concentrated sulfuric acid. Its stable chemical properties provide a reliable guarantee for the production process.
-
Stable and Controllable Quality: Each batch of products undergoes multiple rounds of strict testing, with extremely low impurity content and no difference in quality between batches, making production more worry-free.
✅Packaging, Storage and Transportation, Intimate Service Without Worries
To ensure product quality, we adopt standardized protective packaging: 25kg/bag, with an inner bag of polyethylene plastic film bag tied with a thread rope, and an outer bag of polypropylene plastic woven bag sewn by machine; customized packaging can also be provided according to customer needs.
For storage and transportation, it should be protected from exposure to sunlight and rain, stored in a dry and ventilated warehouse, and padded with a cushion to avoid moisture; it should not be stored or transported together with colored items, and handled with care during loading and unloading to prevent packaging damage.
