Inert Atmosphere Gloveboxes for Lithium-Ion and Solid-State Battery Research

The performance of every lithium-ion cell — and the viability of every solid-state battery under development — depends on what happens during assembly. Lithium metal, lithium salts, sulphide-based solid electrolytes, and most cathode active materials begin to degrade the instant they encounter atmospheric moisture or oxygen. Even trace contamination at the 10–50 ppm level measurably reduces cycle life, lowers initial capacity, and compromises the reproducibility that academic and industrial researchers depend on.

LABPRO glovebox systems are trusted by battery research laboratories at universities, national institutes, and cell manufacturers across India, the US, and internationally. Our purified inert atmosphere workstations consistently maintain oxygen and moisture levels below 1 ppm — the threshold required for reliable lithium metal work, electrolyte preparation, and coin cell or pouch cell assembly. 

​

Why Atmosphere Control Is Non-Negotiable for Battery Research

​

Lithium metal is the most reactive electrode material in common laboratory use. Even in standard lithium-ion work, LiPF₆ and LiTFSI electrolyte salts hydrolyse rapidly in moisture, generating HF that corrodes current collectors and degrades separator integrity. For solid-state electrolytes — whether oxide-based (LLZO, LATP), sulphide-based (LGPS, Li₆PS₅Cl), or polymer-based — the sensitivity is still more acute. Sulphide electrolytes react with moisture to release H₂S within seconds in ambient conditions.

Maintaining O₂ below 1 ppm and H₂O below 1 ppm throughout every step of synthesis, assembly, and characterisation is the baseline requirement for publishable, reproducible results.

Key Battery Research Processes Performed in LABPRO Gloveboxes

• Electrode preparation: slurry mixing, coating, and drying of cathode and anode materials including NMC, NCA, LFP, silicon, and lithium metal.

• Cell assembly: coin cell, pouch cell, and prismatic cell assembly including stacking, electrolyte filling, and sealing under controlled atmosphere.

• Solid electrolyte synthesis: pressing, sintering preparation, and interface formation for oxide and sulphide electrolytes.

• Electrolyte preparation: dissolution of lithium salts in organic solvents, additive incorporation, and quality testing.

• Characterisation and testing: EIS, cycling, post-mortem analysis, and SEM sample preparation within inert atmosphere.

• Sodium-ion and next-generation chemistries: sodium metal handling, hard carbon preparation, and emerging cathode work requiring strict oxygen and moisture exclusion.

Remote monitoring built for active battery research labs

LABPRO is the only glovebox manufacturer to offer myLABPRO — an AI-enabled remote monitoring platform accessible via mobile app or web browser. Battery researchers can track live O₂ and H₂O levels, receive alerts for atmosphere excursions, and review historical purity logs from anywhere. For multi-shift labs and overnight purge cycles, this eliminates manual checks and provides the audit trail that grant-funded research increasingly requires.

​

Choosing the Right LABPRO Configuration for Battery Research

For most university and industrial battery labs, the LABPRO Standard Edition purified glovebox workstation provides the optimal combination of performance and flexibility. Its modular bolted-panel design allows side-by-side expansion as the lab scales, and it accepts the full range of LABPRO process tools including spin coaters, weighing balances, magnetic stirrers, and electrical feedthroughs for electrochemical testing.

For all-solid-state battery (ASSB) research involving sulphide electrolytes, the Ultra Edition with welded panels and leak rate below 0.001% vol/hour provides the ultra-tight environment required. For pilot manufacturing or multi-instrument integration, our large-volume and custom configurations accommodate volumes from 1,000 to 100,000 litres.​​​
