For electrochemical impedance spectroscopy (EIS) on coin cells or 18650 lithium-ion batteries, accurate four-terminal measurements are essential to eliminate additional impedances caused by cable connections. The 18650 / Coin Cell Battery Holders are designed to meet this need, offering gold-plated contacts to reduce contact impedance and optimized cable connections that minimize inductive pickup between current-carrying and sensing leads. These features ensure reproducible lead placement, which significantly reduces variability in measurements, making them ideal for high-precision testing.
Features:
- Four-terminal Kelvin-type measurements.
- The coin cell holder can accommodate 2016, 2025, and 2032 sized cells
- The cylindrical holder is designed for 18650 sized cells.
- Each holder can hold two cells and includes a jumper bar that can be used to place the batteries in series.
- Dual 18650 Battery Holder (992-00158)
- Dual CR2032 Coin Cell Holder (992-00159)
Applications:
- EIS on Coin Cells: Ideal for performing electrochemical impedance spectroscopy on coin cells with high accuracy.
- 18650 Battery Testing: Suitable for impedance measurements on 18650 lithium-ion batteries during cycle life and performance studies.
- Battery Research and Development: Supports research and testing of battery materials, ensuring reproducibility and precision in measurements.
