Glove Box Integrated H₂S Removal for Lithium-Sulfur and Solid-State Battery Research

Technical indicators

Water and oxygen content＜1PPM

Leakage rate＜0.001%vol/h

Product Overview

The TOB-GB1220-N-S glove box is a single-station, specifically designed for solid-state battery research and sulfide-based lithium-sulfur battery material systems, where strict environmental control and toxic gas management are essential.
The system integrates a single-column purification unit, PLC control with touchscreen interface, vacuum system, and a dedicated hydrogen sulfide (H₂S) removal device, forming a fully enclosed inert atmosphere workspace. The enclosure features an inclined operating surface and a removable safety glass front window, ensuring ergonomic operation and safety.
Under standard conditions (20°C, 1 atm, 99.999% inert gas), the system maintains ultra-low moisture and oxygen levels (<1 ppm), providing a stable environment for highly sensitive materials.

Application Focus: Sulfide System & Solid-State Battery

Sulfide-based solid electrolytes are extremely sensitive to moisture and can release H₂S gas when exposed to air. This system is specifically engineered to address these challenges:

● Integrated H₂S removal unit connected to the main circulation pipeline

● Ultra-low H₂O/O₂ control (≤1 ppm capability)

● Fully sealed circulation system to prevent contamination

● Controlled material transfer via electromagnetic valve-driven antechambers

It is particularly suitable for:

● Sulfide solid electrolyte synthesis

● Solid-state battery assembly

● Air-sensitive material handling

● Advanced battery laboratory environments

Glove Box Functional System

● Inert Gas Closed-Loop Circulation

The internal inert gas is continuously circulated through a purification system using a high-performance fan. During circulation, moisture and oxygen are continuously removed to maintain a stable ultra-clean environment.

● Automatic Regeneration System

The purification materials (molecular sieve and copper catalyst) can be regenerated. The regeneration process is fully controlled by the PLC system, ensuring consistent performance over time.

● Automatic Purging System

Atmosphere replacement inside the glove box is achieved through automatically controlled purge valves, ensuring rapid and efficient gas exchange.

● Pressure Control System

The internal pressure is automatically controlled by PLC. The working pressure can be freely set within ±15 mbar, and the system provides automatic protection when exceeding ±16 mbar.

● Vacuum Pump Control

The vacuum pump operates automatically based on system demand and can also be manually controlled.

Technical Specifications

Installation Requirements

Acceptance Standard

Under standard conditions (20°C, 1 atm, 99.999% inert gas, empty chamber operation):

● Moisture level: <1 ppm
● Oxygen level: <1 ppm

Safety Notice (Critical for Sulfide Systems)

For sulfide material applications, strict safety procedures must be :

● Before opening the antechamber or main chamber, working gas must be fully replenished
● The atmosphere must be properly purged before exposure
● Failure to do so may result in H₂S leakage, which is hazardous
● Regular inspection and replacement of H₂S adsorption materials is required
