Abstract:

To analyze the advantages of soft carbon anode material lithium battery which is used as energy storage battery, the basic dynamic performance of a single battery cell was tested using an electrochemical workstation at first. Then, the operating characteristics of the energy storage power station were tested using a container energy storage system. Experimental results show that when the single cell discharged at 3C, the discharge voltage can be kept to be above 2.5 V. Meanwhile, the 3C discharge capacity was 37 611 mA·h, and the discharge ratio can reach 77.17%. The charge-discharge resistance of the battery was relatively smaller, so it had a higher charge-discharge efficiency. During the charging/discharging process, the surface of cluster voltage rose and fell smoothly. The average charge capacity of the battery was 50.45 A·h, the standard deviation was 0.75, the average discharge capacity was 49.60 A·h, and the standard deviation was 0.82. The temperature difference between each single cell was relatively smaller, and the consistency of charge-discharge temperature was satisfying. Therefore, the soft carbon anode material lithium battery cell has excellent charge-discharge performance; meanwhile, the single cells show satisfying consistency when they are used in series or in parallel, which meet the design requirements for energy storage batteries.
