The use and storage of lithium batteries

How to use lithium batteries The concept of lithium batteries is actually very confusing, and there is no uniform statement. Let's take a look at what is said in the national standards (in fact, the recommended national standards). 'Electrician' and 'Primary Battery and Storage Battery' (GB/T2900.41-2008) refer to lithium battery as a battery containing non-aqueous electrolyte, negative electrode lithium or lithium, which can be a primary battery or storage battery. As long as the cathode contains lithium and the electrolyte does not contain water, the range is very wide. Generally, the negative electrode is a metal lithium battery, called a lithium battery, or a lithium primary battery, which is non-rechargeable, represented by lithium manganese batteries, lithium fluorocarbon batteries, and lithium sulfuryl chloride batteries. Generally speaking, how are lithium batteries used? Lithium battery manufacturers will analyze it for you. 1. Lithium batteries can be stored in a clean, dry and ventilated room with an ambient temperature of -5℃-35℃ and a relative humidity of no more than 75%. Avoid contact with corrosive substances and keep away from fire and heat sources. The battery capacity is maintained at 30% to 50% of the nominal capacity. It is recommended that the battery be charged once every 6 months; 2. Lithium batteries cannot be stored fully charged for a long time, and gas expansion is likely to occur during long-term storage, which will affect the discharge performance. The best storage voltage is about 3.8v/piece. 3. Lithium batteries are different from nickel-chromium and nickel-metal hydride batteries because they have a very bad aging characteristic. After a period of storage, even if they are not recycled, they will permanently lose some of their capabilities. Lithium batteries should be stored. After that, the ability to reduce loss is different at different temperatures and different energy states. The speed of aging is different; 4. Due to the characteristics of the use of lithium batteries, lithium batteries can be charged and discharged with high current, and the storage time after full charge cannot exceed 72 hours. It is recommended that the user charge the battery one day before preparing to use it. 5. Unused batteries should be stored in the original packaging, away from metal objects. If the package is opened, do not mix the batteries together. Unpackaged batteries are easily mixed with metals, causing short circuits in Hefei lithium battery manufacturers, causing battery leakage, leakage, explosion, fire and personal injury. One way to prevent this is to store the battery in the original packaging. Lithium batteries have very low self-discharge and can generally be stored for 3 years. The effect will be better if stored under refrigerated conditions. It is a good idea to store lithium batteries at low temperatures. Lithium batteries have a low self-discharge rate, can be stored for more than half a year at 20°C, and most of their capacity can be recycled. Lithium batteries have a self-discharge phenomenon. If the battery voltage remains below 3.6V for a long time, it will cause the battery to over discharge, damage the internal structure of the battery, and reduce the battery life. The correct use of lithium batteries can be attributed to three things: 1. The activation of lithium battery electric vehicles does not require special methods. Lithium batteries will be naturally activated when electric vehicles are driving. Deliberate attempts to use the popular first three 12-hour long charge activation methods are futile and have no effect. 2. When the lithium battery is too low during the driving of the electric vehicle, the lithium battery should be charged as soon as possible. (The fast charging station is strongly not recommended to super damage the battery here. The battery on the market is used up and recharged. It is not all right to charge the battery for a long time. It also depends on the type of battery. It is for the use of electric vehicles as much as possible. Battery-powered, use the best way, practice, in fact, only used for nickel batteries, the purpose of course is to prevent battery memory effect. 3. Charge according to standard time and procedures, even the first three times; (especially, don’t charge time More than 12 hours) The above is the correct charging method of lithium battery that the lithium battery processing company told you, and there are more lithium battery charging problems, you can continue to pay attention to this website.
