What are the factors associated with the capacity of the battery?

The capacity of the battery is usually related to the following factors?: ①The structure and number of the plates. When other conditions are the same, the capacity of the battery depends on the area of u200bu200bthe electrode plate and the porosity of the active material, so the electrode plate is usually made very thin. The thickness of the battery plate is 1.45-3.0mm, ②discharge condition. When the battery is discharged to a large extent, due to the large amount of lead sulfate precipitation, the cross-sectional area of u200bu200bthe pores of the electrode plate is reduced, and it is difficult for sulfuric acid to penetrate the electrode plate from the surface. Therefore, when the discharge current increases, the sulfuric acid that penetrates into the pores of the electrode plate is not enough to compensate for the amount of sulfuric acid consumed per unit time, causing the voltage of the battery to drop rapidly and discharging cannot continue. Therefore, the discharge current increases and the battery capacity decreases. ③The electrolyte temperature. When the temperature decreases, it is difficult for the electrolyte to penetrate the electrode plate due to the increased viscosity. At the same time, when the temperature decreases, the electrolyte resistance will increase and the voltage will decrease, so the battery capacity will decrease. ④The electrolyte density. Increasing the density of the electrolyte can increase the electromotive force of the battery and the ability of the electrolyte to penetrate the active material in the electrode plate, and reduce the resistance of the electrolyte, thereby increasing the capacity of the turtle pool. But if you continue to increase the electrolyte density, it will increase its viscosity. Therefore, when the electrolyte density exceeds a certain value, the electrolyte penetration rate will decrease, and the internal resistance will increase, and the plate vulcanization will increase, which will make the battery The capacity is reduced. So only when the electrolyte density is in the best state, the battery can obtain the maximum capacity. The capacity of the battery voltage of 12v is 2.2AH, 7AH, 14AH, 17AH, 24AH, 32AH, 45AH, 60AH, 80AH, 105AH , 120AH, 160AH, 198AH. The device that converts chemical energy into electrical energy is called a chemical battery, generally referred to as a battery for short. After discharging, the internal active material can be regenerated by charging to store electrical energy as chemical energy; when it is to be discharged, chemical energy is converted into electrical energy again. This type of battery is called a storage battery (StorageBattery), also called a secondary battery. The so-called battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary.
