Why does lack of water affect battery life?

Why does the lack of water affect the battery life? The battery is empty? Many friends don't know much about this problem. But the lack of water in the battery will affect the battery life. Today, lithium-ion battery manufacturers will lead you to understand some of the blind spots in lithium-ion battery maintenance: the electrolyte in the lead-acid battery of an electric car is as valuable as the blood in the human body, and when the electrolyte is lost, the battery is dead. The electrolyte is composed of dilute sulfuric acid and water. During the charging process, it is difficult to prevent water loss. The charging method is different, and the water loss is also different. Normal three-level charging mode, the water loss during charging is more than twice that of colinpulse mode! In addition to the natural life of the battery, there is also a water loss life: a battery loses more than 90 grams of water, the battery is scrapped. At room temperature (25°C), the water loss of an ordinary charger is about 0.25g, and the Kelin pulse is 0.12g. Under high temperature (35c), the water loss of the ordinary charger is 0.5g, and the Colin pulse is 0.23g. According to this calculation, the normal charger will dry out after 250 cycles, and the collinpulse will dry out after 600 cycles. Therefore, the collin pulse can more than double the battery life. Why is my battery ammeter fake? It is much more difficult to make an accurate battery ammeter than to measure how much gasoline is in your car. Over time, your watch will become more and more inaccurate due to the decrease in battery capacity. The cost of length also depends on unpredictable environmental factors such as temperature. This technique cannot measure batteries well. The biggest problem with charging lead-acid batteries is gas extraction. American scientists j.a.m. have studied the causes and laws of gas evolution during the charging process of lead-acid batteries. In order to achieve the lowest gas evolution rate, lead-acid batteries can accept the following charging current curve: The critical gas evolution curve formula is: In the constant current stage, the charging current remains constant, the charge is rapidly increased, and the voltage rises. In the floating charging stage, the charging voltage remains the floating charging voltage; in the constant voltage charging stage, the charging voltage remains unchanged, the charging charge continues to increase, and the charging current decreases. After the battery is fully charged, the current drops below the floating charge conversion current, and the charging voltage drops to the floating charge voltage; the first stage of ordinary three-stage charging is constant current charging. This is important to consider the circuit design more convenient, rather than the best performance of the battery the design of. According to the gas evolution curve of battery charging, the gas evolution of the ordinary three-stage charging process is as follows: During the charging process, the charging current exceeds the critical gas evolution curve, which will only cause the gas and temperature of the battery’s electrolytic water reaction to increase, but cannot increase the battery. Capacity. In the late stage of constant current charging and the early stage of constant voltage charging, the current exceeds the critical gas evolution curve, which leads to gas evolution in the energy storage section of the 18650 battery, resulting in a decrease in battery life. The current exceeding the critical gas evolution curve will only increase the gas and temperature of the battery, but will not be converted into battery power, thereby reducing the charging efficiency. The resulting current diverges widely, making the battery more likely to be unbalanced. Therefore, we don’t know much about the maintenance of lithium-ion batteries. Reasonable water for lithium-ion batteries is conducive to extending the life of lithium-ion batteries! Disclaimer: Some pictures and content of articles published on this site are from the Internet.
