Lithium Hydroxide Storage — LiOH Battery + Grease Tank

Storing Lithium Hydroxide? Start Here

Lithium hydroxide is a versatile chemical used in battery production and grease manufacturing. It comes in both dry crystal form and as a solution. When handling lithium hydroxide, it's important to know its properties: it's strongly alkaline, similar to caustic soda, and can cause severe skin and eye damage. Whether you're in the battery or grease industry, understanding how to store this chemical safely is crucial.

Can you store it in a poly tank?

Yes, you can store lithium hydroxide in poly tanks. High-density polyethylene (HDPE), cross-linked polyethylene (XLPE), and polypropylene (PP) are all compatible with both the dry crystal and solution forms of lithium hydroxide. Fluoropolymers like PVDF also work well. However, avoid using aluminum or galvanized steel, as they will be attacked by the alkaline nature of the chemical.

Watch out for crystallization in cold temperatures

If you're storing lithium hydroxide solutions, be aware that they can begin to crystallize below 30°F. In colder climates, it's important to use heat tracing to maintain the solution in a liquid state and ensure smooth operations.

The safety that actually matters

• Use appropriate personal protective equipment (PPE) to prevent skin and eye contact.
• Ensure proper ventilation to avoid inhaling any dust or fumes.
• Regularly inspect storage tanks and gaskets for signs of wear or damage.

Common questions

What type of gaskets should I use?

EPDM and Viton gaskets are suitable for lithium hydroxide storage. Match gaskets to the manufacturer chart for best results.

Is lithium hydroxide safe to store near other chemicals?

Keep it away from acids and incompatible metals like aluminum to prevent hazardous reactions.

How should I handle spills?

Neutralize small spills with a mild acid and clean up with plenty of water. For larger spills, follow your facility's emergency response plan.
