Battery Manufacturing
Ultra-Low Humidity Solutions for the Energy Storage Revolution
The Industry Challenge
Lithium-ion battery manufacturing is one of the most humidity-sensitive industrial processes in the world. Even trace moisture measured in parts per million during electrode coating, cell assembly, and electrolyte filling causes irreversible lithium dendrite formation, reduced cycle life, safety hazards, and catastrophic cell failure. Drystar India Pvt. Ltd. is India's proven partner for achieving dew points as low as -40°C and Relative Humidity levels of 1% the exact conditions the global battery industry demands.
Key Challenges & Why Change Is Necessary
Understanding the challenges that make a smarter, more reliable solution essential.
Dew Point Control:
Battery dry rooms must maintain dew points between -30°C and -50°C. Conventional refrigerant-based systems cannot achieve or sustain these extremes without enormous energy costs and frequent failures.
Electrolyte Contamination:
Lithium hexafluorophosphate (LiPF6) electrolytes react violently with moisture to produce hydrofluoric acid, causing cell degradation, gas evolution, swelling, and serious safety incidents on the production floor.
Electrode Delamination:
Moisture ingress during electrode slurry coating causes binder degradation, active material delamination, and inconsistent electrode thickness, all of which directly reduce cell capacity and cycle life.
Separator Damage:
High humidity during separator handling or calendaring cause’s micro-tears and dimensional distortion, increasing the risk of internal short circuits and thermal runaway in finished cells
Yield and Safety Losses:
Without ultra-low humidity environments, manufacturers face yield losses often exceeding 15–20%, significant scrap costs, and the ever-present risk of field failures in end-user applications.
The Industry Challenge
Trace moisture during cell assembly and electrolyte filling reacts with lithium, degrading battery performance and creating thermal runaway risks. A single humidity excursion can compromise an entire production batch. Ultra-low RH dry room conditions are a non-negotiable requirement in this industry.
Heavy Duty Industrial AHU Cum Dehumidifier (DIPL-8000 to DIPL-15000)
Product Overview
Drystar's Heavy Duty DIPL Series is engineered for the demanding dry room environments required in lithium-ion cell manufacturing, solid-state battery assembly, and next-generation energy storage production. Handling 8,000 to 15,000 CFM of process air, these systems maintain the ultra-low humidity levels that protect every stage of cell fabrication.
Key Features
How It Suits This Industry
Battery dry rooms require absolute, uninterrupted humidity control. The DIPL Heavy Duty Series operates continuously with automated failsafe controls, ensuring the dry room environment never deviates from specification — even during peak summer humidity conditions in Indian climates.
Why This Is the Best Choice
Drystar is the only Indian manufacturer with a certified track record of achieving -40°C dew point and 1% RH in an operating lithium battery facility. The letter of appreciation from Munoth Industries Limited for India's first lithium cell factory at EMC II, Tirupati, is a testament to this unique capability.
Vertical Industrial AHU Cum Desiccant Dehumidifier (V Series — 1000 to 6000 CFM)
Product Overview
For electrode preparation areas, material staging zones, formation rooms, and battery pack assembly lines that require stringent but not extreme humidity control, the Drystar DIPL Series provides a perfectly calibrated solution. These systems integrate air handling and dehumidification into a single assembly for streamlined installation.
Key Features
How It Suits This Industry
Battery manufacturing facilities encompass multiple zones with varying humidity requirements. The DIPL Series' modular range allows Drystar to design a complete, zone-by-zone humidity management strategy across the entire plant — from material warehousing to finished cell testing.
Why This Is the Best Choice
The DIPL Series' energy recovery options and smart controls make it the most cost-efficient path to compliant dry room humidity levels. Drystar's on-site engineering team provides full system design, installation supervision, and validation support tailored to each battery manufacturer's specific process flow.
