What are the parameters of the power lithium battery?

Parameters of power lithium battery 1. Battery capacity The capacity of power lithium battery is determined by the amount of active material in the battery, usually expressed in milliampere-hour mAh or Ah. For example, 1000mAh can be converted into a charge of about 3600C with a current of 1A for 1h. 2. The potential difference between the positive and negative electrodes of the nominal voltage power lithium battery is called the nominal voltage of the battery. The nominal voltage is determined by the electrode potential of the plate material and the concentration of the internal electrolyte. 3. Charge termination voltage When the rechargeable battery is fully charged, the active material on the electrode plate has reached a saturated state, and then continue to charge, the battery voltage will not rise, the voltage at this time is called the charge termination voltage. The lithium battery is 4.2V or 4.35V. 4. End-of-discharge voltage The end-of-discharge voltage refers to the lowest voltage allowed when the battery is discharged. The discharge termination voltage is related to the discharge rate. Generally speaking, the unit lithium battery is 2.7V. 5. The internal resistance of the battery The internal resistance of the battery is determined by the resistance of the electrode plate and the resistance of the ion current. During the charging and discharging process, the resistance of the image engine and the electrode plate is unchanged, but the resistance of the ion current will vary with the concentration of the electrolyte. It changes with the increase or decrease of charged ions. When the OCV voltage of the lithium battery decreases, the impedance will increase. Therefore, when charging at low power, pre-charge (trickle charging) should be carried out first to prevent too much current from causing excessive heat generation in the power lithium battery. 6. The self-discharge rate refers to the percentage of the total capacity that the lithium battery automatically loses when it is not in use within a period of time. Generally, the self-discharge rate of lithium batteries is 5%-8% at room temperature. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
