Desiccant for Electrochemical Energy Storage

What is Desiccant for Electrochemical Energy Storage?

Desiccant for electrochemical energy storage is a high-absorption calcium chloride and magnesium chloride blend, formulated to meet the demanding moisture control requirements of battery manufacturing and storage. Lithium-ion battery cell manufacturing typically requires relative humidity below 1%, with battery assembly requiring below 10% RH, since even trace moisture can compromise battery performance, safety, and longevity. Desiccants placed within battery packs — often near a breather vent that equalizes internal and external pressure — help absorb any moisture that enters the enclosure, protecting sensitive battery components throughout their service life.

Benefits

• High-absorption blend — the calcium chloride and magnesium chloride formula is well suited to the strict humidity requirements of battery manufacturing
• Precise placement — the connected packet format allows for easy, targeted placement within battery packs and storage enclosures
• Flexible sizing — available in 120g strips or custom sizes to match specific equipment and enclosure dimensions
• Customizable — supports custom packaging materials for specialized battery and energy storage applications

Applications

Desiccant for electrochemical energy storage is used across battery and energy storage manufacturing:

• In lithium-ion battery cell manufacturing and assembly, it helps maintain the extremely low humidity levels required to protect sensitive battery chemistries.
• In electric vehicle (EV) battery packs, it works alongside breather vents to control internal moisture levels throughout the vehicle's service life.
• In energy storage system (ESS) enclosures, it helps protect sensitive electronic and chemical components from humidity damage.
• In supercapacitors and electrochemical capacitors, it supports the moisture control needed for stable, reliable performance.

FAQ

Q1: Why do batteries need desiccant during manufacturing? Lithium-ion battery manufacturing requires extremely low humidity — typically below 1% RH for cell manufacturing and below 10% RH for assembly — since trace moisture can compromise battery performance, safety, and longevity.

Q2: Can this desiccant be reused? No, calcium chloride and magnesium chloride are single-use desiccants. Once saturated, they cannot be dried out and reused.

Q3: What sizes are available? Standard strips are 120g, with custom sizes available to match your specific equipment or enclosure dimensions.

Q4: What is the minimum order quantity? MOQ is based on your specific size and application requirements. Please contact our team for a tailored quote.
