Talk about the concept of the three-Electrode System.
In the field of electrochemical research and battery testing, researchers (students) pay more attention to the potential difference between the working electrode (or auxiliary electrode) and the reference electrode while paying attention to the pressure difference between the working electrode and the auxiliary electrode. The auxiliary channel binding method is adopted to isolate from the main channel without interference, and the data is transmitted synchronously (sampling interval), so as to ensure the accuracy and consistency in the battery tests.
Via different current discharging, we can get the rate performance.
Testing with the μA current unit is more accurate and more convenient.
The design of the μA current unit plays a vital role in the field of current accurate measurement, which is more convenient and more accurate. Generally, magnetoelectric galvanometer can achieve μA level, electromagnetic galvanometer can achieve mA level. Sensitive galvanometer is used for students to check weak current or tiny voltage in DC circuit in the lab. It is a kind of high sensitive magnetoelectric instrument, which can measure the tiny current.
Big news! The latest version of Neware BTSDA is realeased with dQdV function.
The voltage of a Li-ion cell is the difference between the positive electrode and the negative electrode potentials as measured versus lithium metal, as shown in the Figure. During charge discharge cycling the positive and negative electrode curves slip relative to one another. Differential voltage (dV/dQ) and differential capacity (dQ/dV) analysis can be used to measure the alignment of electrodes within a full Li-ion cell without the use of the a 3-electrode cell. This allows cell degradation mechanisms to be understood.
Internal resistance, one of the key characteristics of lithium battery, is an important factor affecting the power performance and discharge efficiency of lithium battery. It is also an important specs to measure the power performance and evaluate the life of lithium battery. Test method: Impose a short-time current pulse to the battery and testing the difference between terminal voltage and open circuit voltage. Dividing the difference by the testing current is considered to be the battery DC internal resistance.The software design supports different test methods and different data value taking methods, own strong compatibility, and can be set and calculated according to requirements.
