Why the battery is not durable in winter
As we all know, any type of battery will have a capacity decline in a low temperature environment. For example, battery cars and electric cars will experience reduced mileage due to low temperatures, and the battery life of electronic devices will not be exceptionally reduced. Then why is the battery not durable in winter? ? How much do you know about this problem? ? Today, the editor of Zhengzhou Kanglida Electronic Power Supply Co., Ltd. will give you some information on this issue. I hope it will be helpful to you. In the future, you can avoid detours when using and purchasing.
1. The compatibility between the electrolyte and the negative electrode separator becomes poor in a low temperature environment, which is suitable for all types of batteries (lead-acid/lithium ion). At the same time, the electrolyte will increase its magnetic viscosity and even freeze with the decrease of temperature. The electrolyte of lead-acid battery is also affected by sulfuric acid solution, and the change in viscosity or even solidification will affect the conductivity of the battery.
can also be understood as the deterioration of electrolyte activity will reduce the transmission capacity, the charging and discharging capacity of the battery will become worse, and the power will be excessively lost during the discharge process.
2. In a low temperature environment, the performance of the sponge fiber active material contained in the lead alloy fence of the lead-acid battery will deteriorate, and the ability of the separator to prevent the active material from falling off will also deteriorate, and the overall working condition of the battery will be very bad.
Lithium batteries will have a serious state of lithium ion negative electrode precipitation in a low temperature environment. These metallic lithium will react with the electrolyte and produce deposits that affect the thickness of the solid electrolyte and affect the battery operating conditions.
In short, the battery is very sensitive to temperature. The lower the ambient temperature the battery's charging and discharging capacity, battery capacity, transfer impedance and service life will be worse or reduced. The ideal operating environment of the battery is about 25 degrees Celsius. The lead-acid battery should not exceed 50 degrees Celsius. It is an ideal state. The lithium battery should not exceed 60 degrees Celsius. Excessive temperature will also cause the battery to deteriorate.
