1.What is the laboratory single channel battery potentiostat galvanostat

Laboratory single-channel battery potentiostat galvanostat constant current, simply put, is an instrument that can accurately control the current and potential in electrochemical experiments. It allows researchers to perform precise electrical operations and measurements on batteries or other electrochemical systems under specific experimental conditions. "Single channel" means that the device can only process one sample of an electrochemical experiment at a time, which makes it uniquely valuable in research scenarios that require a high degree of focus and fine control.

In terms of potential function, it can maintain the constant potential of the working electrode relative to the reference electrode. By constantly monitoring and adjusting the voltage applied between the working electrode and the opposite electrode, it is ensured that the potential of the working electrode is not interfered by other factors in the system and is always maintained at the set value. It is very important to study the kinetic process of electrode reaction and the electrochemical properties of electrode materials. For example, when studying the charge and discharge behavior of the positive electrode material of a new lithium battery, precisely controlling the electrode potential can accurately analyze the reaction mechanism of the material in different potential intervals.

The constant current function is to ensure that the current through the electrochemical system remains constant. Regardless of how the resistance of the system changes, the device automatically adjusts the output voltage to maintain the preset current value. Constant current mode is widely used in battery charging and discharging test. By setting a constant charge or discharge current, key performance indicators such as battery capacity, charge and discharge efficiency, and cycle life can be accurately evaluated.

2. Working principle

(1) Potential control principle

The potential control of laboratory single channel battery potentiostat galvanostat is based on negative feedback mechanism. A high-impedance voltmeter inside the device measures the potential difference between the working electrode and the reference electrode in real time. When this potential difference deviates from a preset value, the feedback circuit quickly responds by adjusting the voltage applied between the working electrode and the opposite electrode. This adjustment process is achieved through a power amplifier that provides enough current to change the potential of the working electrode back to a preset value. The whole process is dynamic and fast, ensuring that the potential is always stable during the experiment.

(2) Current control principle

In constant current mode, the operating principle of the device is also based on feedback control. At this point, the device monitors the current passing through the working electrode. When the current deviates from the set value, the feedback system adjusts the voltage applied between the working electrode and the opposite electrode to change the current size. If the current is below the set value, the device will increase the output voltage, otherwise it will reduce the voltage. This precise current control capability enables researchers to simulate the battery charging and discharging process under various practical application scenarios, providing a reliable means for the study of battery performance.

3. Application scenarios
