Differential Electrochemical Mass Spectrometer (Li-ion Battery), Shanghai Sunny Hengping Scientific Instrument Co., Ltd (CAT#: STEM-AI-0102-YJL)

Differential Electrochemical Mass Spectrometer (Li-ion Battery) is manufactured by Shanghai Sunny Hengping Scientific Instrument Co., Ltd. The product can accurately quantify the amount of gas consumed and generated during the reaction of lithium-ion batteries. By combining the amount of electricity Q passed during the battery reaction, the reversible main reactions and irreversible side reactions of lithium-ion batteries can be studied. Side reactions in lithium-ion batteries are usually accompanied by the production of gases, such as H2, CO, CO2, etc. Therefore, the determination of the type and content of the gas, combined with the electricity calculation and isotope tracking, can further clarify the change of the cathode material during the operation of the lithium-ion battery.

The trap can exclude the interference of impurity gases (H2O and CO2, etc.) on the experiment
A spiral gradient gas flow field is formed above the battery, which makes the gas flow more stable, greatly reduces the probability of occurrence of eddy currents, and also improves the gas transmission efficiency
Customers can set the flow rate of the flow controller according to the different experimental systems
Cold trap and Teflon membrane can remove the organic electrolyte in the sample gas to ensure the accuracy of the data
High-precision capillary injection components are used to ensure gas consistency
The filament is made of thorium-iridium wire, which has strong water resistance and oxidation resistance, and can withstand long-term continuous sample gas injection and maintain long-term stability
The mass spectrometry software gives both ion current and concentration data for easy selection and viewing
