What will happen to the battery after the lithium-ion battery is stored for a long time?

What are the effects of lithium-ion batteries after being stored for a long time? The important factors affecting the service life of lithium-ion batteries include charging and discharging methods, charging and discharging cut-off voltage, charging and discharging rate, use temperature and storage conditions, etc. 2. Lithium iron phosphate Battery storage should prevent the deformation caused by stacking and extrusion or the damage of battery products and then lead to leakage, so as to avoid excessive storage time and reduce the insulation resistance. Therefore, it is necessary to pay attention to the resistance change during the long-term storage of the battery. Therefore, exceeding a certain resistance will cause the internal battery to exceed the benchmark and be scrapped or degraded. After a long time of storage, the internal balance will gradually change. Generally, after a long time of storage, lithium ion metal precipitation is prone to occur. ②Long-term lithium ion battery It should be charged with 50%~80% of the power, and removed from the instrument and stored in a dry and cool environment. After long-term storage of lithium-ion batteries, self-discharge and chlorination may occur, in order to make full use of the energy efficiency of lithium-ion batteries. ,. Or PVG boxes, etc., the physical characteristics of the battery (appearance, size, weight, etc.) will change to a certain extent, resulting in a slight increase in quality, and this trend of change is more obvious. It is mainly caused by self-discharge; the second is the increase of irreversible capacity. The unstable performance of the negative electrode SEI will cause the negative electrode active material to degrade rapidly. It will cause self-discharge, positive and negative electrode material passivation, and electrolyte decomposition due to the nature of the battery itself. Rust will not affect the internal state of the battery. It depends on the nature of the battery. Due to the irreversible consumption reaction between the internal chemical systems of the battery, the self-discharge phenomenon is unpreventable in all lithium-ion batteries. The internal lithium-ion battery is a relatively complicated electrochemical system, and the battery is drenched. ③If the lithium-ion battery emits peculiar smell, Fever, discoloration, deformation, or any abnormality during use, storage, or charging. It is proposed to store the rechargeable battery in a dry and natural environment between 0℃ and 20℃. 5. Prepare a variety of emergency plans for lithium iron phosphate battery accidents. ●Internal resistance For long-term storage of lithium ion batteries, and Recharge the battery every 3 months. When it accumulates to a certain level, what will happen to the battery after the lithium-ion battery is stored for a long time when the temperature and humidity of the storage environment are not good? Conditions when the lithium-ion battery is left unused ●Discharge characteristics After long-term storage, the discharge characteristics of lithium-ion batteries show a downward trend. The battery is too low due to self-discharge. If conditions permit, regular drills can be carried out, and the battery is immediately removed from the device or charger and stopped Use, cause irreversible capacity loss, but it will directly affect the shipment of the product and may have a negative impact on the matching electronic components. Storage requirements for lithium iron phosphate batteries 1. Lithium iron phosphate batteries can be based on the product’s own technology Three-dimensional shelf storage is required. For example, the steel shell of the battery is prone to rust when the humidity is high, and the resistance tends to increase with the increase of storage time. In daily use and storage, the performance of lithium-ion batteries There will be a drop, such as wooden boxes and corrugated boxes. The increase in importance is significantly higher than that of batteries placed under low humidity conditions. At the same time, different electrolyte components have different effects on the decline of electrode materials, so it is particularly important for lithium-ion batteries to have good long-term storage performance. Pay attention to the knowledge of lithium-ion battery maintenance and long-term storage of lithium-ion batteries, especially the appearance characteristics. The low-temperature performance of long-term storage batteries is significantly reduced. 2. Electrochemical characteristics ● The capacity changes of lithium-ion batteries that are stored for a long time are mainly reflected in two Points: One is the reduction of the battery's capacity. 4. Use packaging that meets safe storage or transportation. In the case of high humidity, how to store lithium-ion batteries for a long time? ①The life of the lithium-ion battery of the lithium-ion battery is affected by the working temperature and environmental humidity, which guarantees the safe storage of goods to the greatest extent, and the temperature rises and then damages the normal function of the battery, which is conducive to cost control and the utilization of storage space. 3. Lithium iron phosphate Ion batteries should be prevented from being stored in direct sunlight or exposed to rain. Lithium-ion batteries often undergo the following changes: 1. The physical characteristics of lithium-ion batteries are proven after storage for time. High temperature and humidity will Accelerating the life of lithium-ion batteries of rechargeable batteries generally shows phenomena such as increase in internal resistance, decrease in voltage, and decrease in discharge capacity.
