What is the basic performance of the battery

What is the basic performance of the battery (1) the open circuit voltage of the battery (2) the internal resistance of the battery (3) the working voltage of the battery (4) the charging voltage The charging voltage refers to the external power applied to both ends of the battery when the secondary battery is charging Voltage. The basic charging methods include constant current charging and constant voltage charging. Generally, constant current charging is used, and its characteristic is that the charging current is constant during the charging process. As the charging progresses, the active material is recovered, the electrode reaction area continues to shrink, and the polarization of the motor gradually increases. (5) Battery capacity Battery capacity refers to the amount of power obtained from a battery, usually expressed as C, and expressed as Ah or mAh in units. Capacity is an important indicator of battery electrical performance. The capacity of the battery is usually divided into theoretical capacity, actual capacity and rated capacity. The battery capacity is determined by the capacity of the electrodes. If the capacity of the electrodes is not equal, the capacity of the battery depends on the electrode with the smaller capacity, but it is by no means the sum of the positive and negative capacities. (6) Storage performance and lifespan of batteries One of the important features of chemical power sources is that they can release electrical energy when in use and store electrical energy when not in use. The so-called storage performance for the secondary battery is the charge retention capability. Regarding the secondary battery, the service life is an important parameter to measure the performance of the battery. After the secondary battery is charged and discharged once, it is called a cycle (or this cycle). Under a certain charging and discharging system, the number of charging and discharging times that the battery can withstand before the battery capacity reaches a certain specified value is called the service cycle of the secondary battery. Lithium-ion batteries have excellent storage performance and long cycle life. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
