DSC is an important testing method for researching the thermal behavior of batteries and materials. It can be used to analyze electrolyte stability, electrode material phase transitions, SEI film formation, and exothermic reactions, providing thermodynamic basis for material screening, thermal stability research, and next-generation battery system development.
Working Principle
Through programmed linear temperature ramping, the instrument measures the heat flow difference between the sample and reference in real time as a function of temperature or time, thereby characterizing endothermic and exothermic thermal effects of the material.

FTIR Spectroscopy
Product 03
FTIR Gas Comprehensive Analysis System
Product Introduction
In battery thermal runaway and industrial safety research, gas composition is an important basis for determining hazard potential. The FTIR Gas Comprehensive Analysis System is used for real-time, multi-component analysis of complex gas mixtures, identifying gas composition and concentration to provide data support for hazardous gas identification, safety assessment, and process monitoring.
Working Principle
Utilizing the characteristic absorption signals of different gas molecules in the infrared spectrum for identification, the system achieves qualitative and quantitative analysis of mixed gases by analyzing spectral features.
System Introduction
This coupled testing system enables real-time continuous analysis of gas concentrations during battery failure processes. It not only simplifies testing procedures and reduces testing time, but also allows real-time testing of up to 50 gas components. First, a battery thermal runaway test is conducted in a gas generation tank, triggering thermal runaway through different methods such as heating, needling, or charge/discharge cycling. Data such as pressure, temperature, and gas volume during battery thermal runaway are collected, and the concentration and composition of gases released by the battery are then analyzed through the FTIR online gas analyzer.
Explosion Testing
Product 04
Gas Explosion Limit & Maximum Explosion Pressure Tester
Product Introduction
Used to measure the explosion limits (LEL/UEL) and maximum explosion pressure (Pmax) of combustible gas-air mixtures, obtaining key safety parameters related to gas flammability and explosion dynamics.
Can be used for lithium battery thermal runaway gas hazard assessment, chemical process design, and industrial safety research, providing critical test data for ventilation systems, explosion-proof solutions, and safety risk assessments.
Working Principle
Combustible gas and air are mixed under specified conditions and uniformly stirred, then subjected to controlled ignition within a sealed combustion chamber. Explosion pressure and explosion limit parameters are obtained through pressure sensors and gas analysis.
