Audited Supplier | Barium sulfate for batteries |
| Chemical formula: BaSO4 |
| Performance: This product is modified and ultra-fine in battery applications. Because it does not contain iron, it is not easy to discharge and has good dispersibility. It can be highly dispersed in the negative electrode active material. It has more crystalline centers during discharge and better prevents lead ratio The surface area shrinks, effectively delaying the passivation of the plate, the battery starts fast in actual use and has a long life. |
| Application: It is an indispensable component in various types of negative active materials of lead batteries, and is the most commonly used inorganic expander in battery manufacturing. It has lattice parameters similar to lead sulfate and is an isomorphous substance. |
| Packing: Packing according to user requirements. |
