LIBcell charge is a cell for in-situ Raman analysis of the electrode surface. It measures the opposite electrode surface by passing laser through the holes of the counter electrode as well as the separator. Gas generated by charging and discharging will escape from the observation part located at the center of the cell and interference that affects the measurement is restrained

Specifications

Analysis by the use of LiBcell charge and Raman imaging visualizes the difference in how the progress status of charging reaction varies according to the locality. The result of in-situ Raman imaging of graphite anode is shown in the lower right image. Charging reaction is known to be in progress from the indication of high crystallinity due to the discharge status. Various charging and discharging process can be examined by in-situ with the change in electrode material and electrolyte solution, shift between anode and cathode along with the adoption of LIBcell charge.

Measure the electrode surface at the bottom by making small holes on the separator as well as the counter electrode and let laser pass through. The periphery of the opening which has a higher efficiency of charging and discharging reaction is targeted for analysis.
