The Neware CT-8002S-5V100mA-CV represents a major shift for Neware. Historically, they were known for "DC" testing (cycling), while "AC" testing like Electrochemical Impedance Spectroscopy (EIS) was left to expensive potentiostats. With the 8000S series, Neware has integrated EIS directly into the cycler, allowing you to measure the internal impedance of your pouch cells across a frequency range without moving the cell to a different machine.

The CT-8002S handles EIS by superimposing a small AC sine wave onto the DC signal. (1) Frequency Range: Typically 10 mHz to 10 kHz (some high-end configurations reach 100 kHz). (2) Impedance Accuracy: Generally ±0.5% to ±1%. (3) In-situ Capability: The "S" (Small/Special) series is designed to perform these measurements while the battery is cycling. You can program the system to "Do an EIS sweep every 50 cycles" to track how your internal resistance grows over time. (4) Multi-Channel Synchronicity: Unlike a single-channel potentiostat, if you have an 8-channel CT-8002S, you can perform EIS on multiple pouch cells simultaneously (or in very rapid succession), significantly speeding up your material screening.
