The In-situ Gas Analysis System for Lithium Battery Thermal Runaway is an advanced testing platform designed to trigger and monitor battery thermal runaway events within a controlled environment. Using a battery cell pressure vessel as the primary trigger carrier, the system integrates real-time signal detection, gas sampling, and online gas composition analysis. It enables flexible sample loading, thermal runaway initiation, and precise monitoring of generated gases, while providing reliable measurement data for gas volume, gas evolution rate, and explosion pressure. This system supports research, production, and safety assessment of lithium batteries, contributing to effective hazard evaluation across multiple applications.
Standards
The system is compliant with the following standard:
(1) UL 9540A-2025 – Standard for Testing Thermal Runaway Fire Propagation in Battery Energy Storage Systems

Features
High-Strength Stainless Steel Vessel
304 stainless steel chamber ensures corrosion resistance, high-temperature durability, and mechanical integrity. Design pressure 3 MPa, constant operating pressure 2.5 MPa, with a safety valve for rapid pressure relief.
Multi-Channel Battery Parameter Monitoring
Supports online monitoring of voltage, temperature, and pressure through K-type high-temperature thermocouples and high-precision imported sensors, covering heating, overcharge, and nail penetration trigger modes.
Integrated Environmental Control
Vacuum extraction, nitrogen filling, exhaust, and oxygen concentration detection (0–100% Vol.) are included. Video monitoring allows real-time observation of thermal runaway events.
Automated Gas Sampling System
Multi-layer sample lines with real-time pressure monitoring ensure continuous, accurate gas sampling. Automatic switching prevents blockage and maintains system integrity.
Heated Sampling Lines
Prevents intrusion of liquid electrolyte into analytical instruments, reducing interference and improving gas composition measurement accuracy.
Advanced Gas Analysis
FTIR spectrometer and electrochemical sensors, combined with a professional analysis model, enable precise online measurement of complex gases produced during battery thermal runaway.
User-Friendly Control Software
Intuitive interface, low latency, real-time monitoring of gas composition, battery parameters, and environmental conditions.
Extended Data Processing
Automatic calculation modules for gas evolution rate and total gas volume, with seamless integration into the software for data visualization and reporting.
