This product is designed for in-situ Raman spectroscopy studies of battery systems, enabling real-time monitoring of electrode reactions and interfacial dynamics. Constructed from 304 stainless steel with a sapphire window, the cell offers chemical resistance and optical transparency for laser excitation and signal collection. Multiple configurations are available: the E702 supports two-electrode setups, while the E703 accommodates three-electrode or two-electrode plus gas environments. The E704A and E704B variants include gas ports and, in the case of E704A, additional negative electrode protection for air-sensitive materials. These features make the cell suitable for investigating lithium-ion, sodium-ion, and other next-generation battery chemistries under controlled atmospheres. It provides a reliable platform for correlating electrochemical behavior with structural evolution, supporting both academic research and industrial R&D in energy materials.
