3. Application Scenario
Application Cases
Case 1: EIS Analysis–Different Cell Impedance Analysis
High-frequency EIS impedance range: 0.01Hz~100kHz, meeting the high-frequency impedance test requirements of 10mΩ~1kΩ level batteries.
Compared with the EIS test results of well-known foreign electrochemical workstations, the error is within 5%
Case 2: Cell Cycle Impedance Test
1) Rct decreases as SOC increases;
2) Rct increases as DOD increases
Case 3: Accurate DCIR Performance
1) Three devices with different voltage accuracies were used to perform DCIR (Direct Current Internal Resistance) testing on five groups of coin cells, with data points collected every 0.1 seconds.
2) The results demonstrated that higher voltage accuracy yields better consistency in the DCIR of coin cells.
Case 4: CV(Cyclic Voltammetry) to Evaluate Materials Properties
The peak current of the reversible reduction is proportional to the square root of the scan rate.
It is consistent with the CV (Cyclic Voltammetry) curves obtained from the electrochemical workstation.
Case 5: dQ/dV Curves to Evaluate Material Phase Changes
dQ/dV Curve Analysis:
Curve Smoothness:
High-precision equipment: dQ/dV curves are smooth and continuous, capable of capturing subtle electrochemical changes.
Electrochemical reaction characteristics:
High-precision equipment: Clearly reveals characteristic peaks of multi-stage reactions in the battery, uncovering material phase transitions or side reactions.In dQ/dV curve analysis, high-precision equipment is crucial for studying electrochemical details, improving data reliability, and identifying material characteristics. Low-precision equipment can perform basic testing but may miss critical details, especially in high-demand research scenarios.
Case 6: Charge and discharge Evaluation of Materials Gravimetric Capacity
Gravimetric capacity tests were conducted on eight graphite half-cells, demonstrating better consistency in specific capacity!
Case 7: Evaluation of Coulombic Efficiency in Cells via Charge and Discharge Testing
Coulombic Efficiency Testing:
A lifetime prediction model based on coulombic efficiency can forecast battery capacity degradation. For effective lifetime prediction, the accuracy must be maintained at least at 1‱, with noise interference kept below 10 ppm.
Case 8: Evaluation of Cells Self-Discharge Under Constant Voltage Charging
High precision supports leakage current testing of large capacity and low internal resistance cells
Coin Cell Leakage Current Test:
Electrodes: NCM (ф14 mm) vs. Lithium (ф20 mm)
LITH High-Precision Electrochemical Property Analyzer is capable of monitoring currents as low as the nanoampere (nA) level, supporting the measurement of minute leakage currents.
