What is the basic function of the battery?

The basic functions of the battery (1) the open circuit voltage of the battery (2) the internal resistance of the battery (3) the operating voltage of the battery (4) the charging voltage The charging voltage refers to the voltage applied to both ends of the battery by the external power source when the secondary battery is being charged. The fundamental method of charging is constant current charging and constant voltage charging. Generally, constant current charging is used, and its characteristic is that the charging current is stable during the charging process. As the charging progresses, the active material is recovered, the electrode response area continues to shrink, and the polarization of the motor gradually increases. (5) Battery capacity The battery capacity refers to the amount of electricity obtained from the battery. C is commonly used to indicate, and the unit is commonly used to indicate Ah or mAh. Capacity is an important goal of battery power. The capacity of the battery is usually divided into theoretical capacity, practical capacity and rated capacity. The capacity of the battery 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 capacity of the positive and negative electrodes. (6) One of the primary features of battery storage function and lifespan chemical power supply is that it can release electrical energy when in use, and can store electrical energy when not in use. The so-called storage function is related to rechargeable batteries. Regarding secondary batteries, it is an important parameter to measure the performance of the battery when using the lifespan. After the secondary battery is charged and discharged once, it is called a cycle (or this cycle). Under certain charging and discharging criteria, the number of charging and discharging times that the battery can withstand before the battery capacity reaches a certain specified value is called the operating cycle of the secondary battery. Lithium battery has excellent storage function and long cycle life. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
