What are the important parameters for lithium battery customization?

Important parameters of customized lithium battery Lithium battery as a secondary battery can be charged and discharged multiple times. Four important parameters should be considered in the customization of lithium batteries. These four parameters determine the performance of the battery. 1. Rated voltage The potential difference between the positive and negative electrodes of a lithium battery is called the nominal voltage, which is determined by the information of the positive and negative plates and the concentration of the electrolyte. The nominal voltage is volts (V), which is the voltage at which the battery has the longest continuous discharge time. 2. Extra capacity The extra capacity of a lithium battery is determined by the amount of active material in the battery, usually in milliamperes or milliamperes. Customized lithium batteries for general industry, customized additional capacity is not small. 3. Internal resistance The internal resistance of a lithium battery is determined by the resistance between the ion current in the battery and the plate resistance, and the plate resistance is closely related to the battery voltage. When the battery voltage drops, the internal resistance increases. Therefore, in the case of low-voltage charging, it is necessary to perform pre-charging to prevent the high heat of the battery caused by the high current, which may cause explosion. 4. Self-electric rate The self-charge rate can also be called self-discharge, which refers to the percentage of the total power consumed by the lithium battery after not being used for a period of time. Generally, the custom-made self-charge rate of a normal lithium battery is 5% Between 8%. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
