In-situ Cell Thickness Expansion Tester - CL-A01

An instrument that measures cell thickness change during charge-discharge to 1-micron precision. It offers two operating modes, constant-pressure and constant-gap: the first holds the load fixed and measures expansion, while the second locks the gap and monitors pressure change. It can also switch pressure automatically based on the charge-discharge signal and apply staged pressure adjustment at set cycle intervals.

Key Features

• Thickness change measurement at 1 μm precision with 0.1 μm resolution
• Constant-pressure mode holds the load fixed and measures expansion
• Constant-gap mode locks the gap and monitors pressure change
• Automatic pressure switching driven by the charge-discharge signal
• Staged automatic pressure adjustment at set cycles, for example every 100 cycles
• Real-time software with ≤1 s sampling and data protection against power loss
