This product is designed for real-time optical and Raman imaging of lithium-ion battery electrode materials during electrochemical cycling, enabling direct observation of dendrite growth in anode materials and supporting in situ studies of all-solid-state batteries. The cell features a replaceable electrode design and adjustable internal thickness to accommodate various sample dimensions, while a fluorine gel O-ring ensures reliable sealing. A high-transmittance optical window (25 mm diameter) minimizes signal loss for clear microscopy or spectroscopy. The compact cell (55×42×20 mm) and stainless steel bracket (92×65×21 mm) allow easy installation, disassembly, and cleaning. Optional upgrades include heating and pressure monitoring, and the window can be swapped between quartz, sapphire, or other materials for specific experimental needs.
