Raman Battery Chamber
The In-situ Raman Battery Chamber enables direct Raman analysis of battery cross-sections,
providing clear insight into interfacial behavior between anode, cathode, and separator layers.
Designed for operando studies of both liquid electrolyte and solid-state batteries, the system
features integrated pressure control and force monitoring, enabling pressure-coupled mechanistic
studies with integrated force control. Convenient electrolyte injection and simplified sample
preparation ensure reliable and efficient in-situ measurements.
