Observe the growth of lithium dendrites in the thickness direction of the lithium foil during charge–discharge cycling; the structure is double-sided. Imaging must be performed under an optical microscope at magnifications of 1,000× or higher.

Primarily used for testing solid-state electrolyte batteries, equipped with a pressure sensor.

A specialized electrolytic cell compatible with synchrotron radiation facilities, integrating a three-electrode electrochemical system and an X-ray‑transmissive window, enables simultaneous CV and potentiostatic electrolysis while concurrently acquiring XRD, XAFS (XANES/EXAFS), and SAXS data, thereby enabling real-time, in situ monitoring of the catalyst’s crystalline phase, oxidation state, and coordination structure during electrocatalytic processes.

1. Can be used for testing the replenishment of electrolyte and charge in soft-pack batteries.
