Factors affecting the health of no 5 alkaline battery.
In recent years, various countries around the world have carried out a lot of scientific research on the embrittlement mechanism and regularity of no 5 alkaline battery. It is widely believed that the accumulation of lithium ion batteries, the increase in SEI film thickness and the damage of active materials are responsible for the embrittlement and volume attenuation coefficient of rechargeable batteries. The main reason. The misuse of no 5 alkaline battery will accelerate the aging of the battery, and normal charging and discharging will also affect the health of the battery and accelerate the aging of the battery.
1. The harm of temperature to the SOH value of rechargeable batteries.
It is generally believed that temperature is an important factor affecting the health of the battery. Temperature has a two-way impact on battery performance. On the one hand, high temperature will accelerate the chemical changes inside the battery and improve the efficiency and performance of the battery. On the other hand, high temperature will cause some irreversible damage. Chemical changes occur, resulting in the reduction of active materials in the rechargeable battery, resulting in embrittlement and volume attenuation coefficient of the rechargeable battery. Scientific research shows that high temperatures will accelerate the growth of the battery level SEI film, increase the difficulty of lithium-ion batteries passing through the SEI film, and increase the internal resistance of the battery.
2. The harm of charging and discharging current rate to SOH components.
A 300-cycle test of three different charge-discharge ratios was carried out using Sony 18650 rechargeable battery. The results showed: battery power attenuation coefficient, battery power reduction, battery internal resistance increase, battery internal resistance increase, battery internal resistance increase, battery internal resistance increase, battery internal resistance increase, battery internal resistance increase, battery internal resistance increase, battery internal resistance increase, battery internal resistance increase, battery internal resistance increase The resistance increases; in addition, the charging and discharging of polymer cells will generate a large amount of heat inside the battery, accelerating the aging of the battery. According to transmission electron microscopy observations, it is found that the SEI film on the surface of polymer battery cells has a lower charge and discharge level. Multiple charge and discharge film thickness.
3. The harm of deep discharge to the SOH value of rechargeable batteries.
Battery charging is closely related to the health and aging of the battery. Some people believe that the battery has accumulated total transfer energy, and the volume attenuation coefficient and aging of the battery are analyzed based on the total transfer energy. Through cyclic experiments on no 5 alkaline battery at different charging and discharging depths, Fei Xiang et al. analyzed the relationship between the accumulated migration energy of the battery and the battery capacity attenuation coefficient, and found that before the battery capacity attenuation coefficient reached 85%, the battery was charged deeply, discharged deeply, and discharged shallowly. The accumulated transfer energy under the two methods is basically the same. When the battery capacity attenuation coefficient reaches 85%~75%, the accumulated transfer energy and energy efficiency of the battery under the deep charge and deep discharge method are both better than the shallow discharge method.
4. The impact of circulation system spacing on the SOH concentration value of rechargeable batteries.
The cycle interval between charging and discharging a lithium battery pack will also affect the aging process of the battery. Different cycle intervals match different internal resistances of the batteries, so the battery heats up and reacts slightly differently during the cycle. , long-term operation will affect the health and aging of the battery. Experts believe that the SOC range of batteries is 20% to 80%, which is beneficial to the health and circulatory life of batteries.
5. The harm of battery charging cut-off voltage to SOH value;
Overcharging and losing power of the lithium battery pack will affect the health of the battery, and poor voltage and low voltage limits will also affect the health of the lithium battery pack. As the charging and discharging voltage decreases, the internal resistance of the battery increases, causing the battery to become hot inside. At the same time, side effects increase, the battery active material decreases, the negative grade high-purity graphite flakes collapse, the battery accelerates aging, and the attenuation capacity increases. If the battery charging cut-off voltage is too high, the internal resistance of the battery will increase, and the internal heat of the battery will increase. Overcharging the battery will cause the negative stage to cause "lithium precipitation", which will lead to increased adverse reactions, affecting battery power and aging.
All in all, battery operating temperature, battery charging rate, charge and discharge depth, cycle time interval, battery charging cut-off voltage, etc. will affect the health and service life of the battery. The scientific research on factors affecting battery health is still in the stage of qualitative analysis. This qualitative analysis of influencing factors and the coupling relationship between each factor is a difficult problem for scientific research, and it will also be a hot spot for future scientific research on battery health and service life. .
