Learn MoreAs one of the key testing indexes for the performance of lithium battery, the testing of charging and discharging characteristics can directly show the capacity and performance of lithium battery. The advantages of lithium battery mainly have no pollution, no memory and large monomer capacity, which are widely used in various electronic products.
This research provides a reliable method for the analysis and evaluation of the charging and discharging characteristics of lithium batteries, which is of great value for improving the safety and efficiency of lithium battery applications.
The cell was charged and discharged with a current of ±40 mA between 2.75 V and 4.2 V. Voltage increases steadily while charging the battery. During this step, lithium ions are extracted from the cathode and intercalate into the anode's graphite layers. The cell is potentiostatically held at 4.2 V after reaching the upper voltage limit.
Experimental results show that this method can effectively measure the actual voltage of lithium-ion battery under different rated voltages, and the measured voltage waveform is very stable and almost without distortion.
Lithium-ion cells get charged and discharged, both during life cycle testing and during formation. However, the goals for life cycle testing versus formation are very different. Correspondingly, the charging and discharging, and associated activities, are also very different.
Compared with other batteries, the charge and discharge characteristics of lithium-ion batteries are high energy density, low self-discharge rate, fast charge and discharge rate, and good cycle life. The high energy density of lithium-ion batteries means that more energy can be stored with a relatively small size and weight.
