EQ-SC-18650 Split Type Test Cell is designed for testing 18650 batteries. Its detachable design allows you to test the cycling behavior as well as structural changes of electrodes easily and quickly. Optional quartz case will allow you to do in-situ Raman, Infrared, or X-ray analysis.
Note: Customized (Au coated) test cells are non-returnable and non-exchangeable.
MTI has granted the patent 2016205320104 for the Split Type Cells for the Cylindrical Batteries with PTFE/Quartz Liner since June 2016.
