Lithium battery electrolyte is generally composed of lithium salt and organic solvent. The electrolyte plays the role of conducting ions between the positive and negative electrodes of the lithium battery, which is the guarantee for the lithium ion battery to obtain the advantages of high voltage and high specific energy. The electrolyte is generally prepared from high-purity organic solvents, electrolyte lithium salts, necessary additives and other raw materials under certain conditions and in a certain proportion. The important components of lithium-ion battery electrolyte are as follows: 1. Ethylene carbonate: Molecular formula: C3H4O3, transparent and colorless liquid (>35℃), crystalline solid at room temperature, a good solvent for polyacrylonitrile and polyvinyl chloride. 2. Propylene carbonate, colorless and odorless, or light yellow transparent liquid, soluble in water and carbon tetrachloride, miscible with ether, acetone, benzene, etc. This product should ...

With the widespread application of ternary lithium batteries, the frequency of new energy vehicle charging misfires is also increasing, and everyone's focus on new energy vehicles has gradually shifted from cruising range to safety. Ternary lithium battery is not recommended to be fully charged Many people say that the lithium iron phosphate battery should be fully charged, and the ternary lithium battery should not be fully charged until more than 90. The reason is that the voltage of the lithium battery will increase after being fully charged, which will affect the activity of the electrolyte and the positive and negative materials, resulting in battery capacity attenuation. At the same time, the ternary lithium battery is not suitable for over-discharging, and it is best to charge it when the power is left at 30%. Advantages and disadvantages of ternary lithium battery The advantage of the ternary lithium battery is that the energy density per unit volume is highe...

What matters should be paid attention to when installing? This is a topic that everyone is more concerned about and discussed. Lithium-ion batteries have the advantages of light weight, small volume, large capacity, and no memory effect, so they have been widely used. Many digital devices use lithium-ion batteries as power sources. The following editor will help you explain the assembly process and installation precautions of lithium-ion battery packs. 1. Lithium-ion battery pack assembly process Tools/raw materials: positive electrode material, negative electrode material, separator paper steps/methods ①Pulping: The powdered positive and negative active materials are mixed with special solvents and binders, and the positive and negative positive and negative materials are made into slurry after stirring at a high speed evenly. ②Coating film: The prepared slurry is uniformly coated on the surface of the metal foil and dried to form positive and negative pole pieces respe...

The 18650 lithium-ion battery capacity is distributed between 1000mAh and 3000mAh. Due to the particularly hot market, the price of today's 18650 lithium-ion batteries is extremely chaotic. The capacity of the 18650 lithium-ion battery pack is of concern to many industrial users and consumers, because the larger the capacity of the 18650 lithium-ion battery, the longer the usage time and the longer the power supply can be supplied to the user. What are the important factors that affect the capacity of 18650 lithium-ion batteries? The battery capacity is affected by the degree of aging. We all know that when the capacity decays to a limit value, the battery is eliminated. It can be seen that there is an absolute correlation between the two. Secondly, the capacity is also affected by temperature. At low temperatures, the activity of the active material decreases, and the amount of ions that can be supplied decreases, and the capacity will inevitably decrease. The capa...

There are many types of lithium-ion batteries, such as power-type lithium-ion batteries, capacity-type lithium-ion batteries, and consumer lithium-ion batteries. Power-type lithium-ion batteries and capacity-type batteries are different in terms of materials and processing techniques. The difference in discharge characteristics means that the scope of use of the two is very different. When purchasing a lithium-ion battery pack, it is necessary to distinguish between the two to prevent a bad impact on the load. 1、The difference between power lithium-ion batteries and capacity lithium-ion batteries The power lithium-ion battery pack refers to the power source that supplies the power source for the tool. At present, it mostly refers to the lithium-ion battery pack that supplies power for electric vehicles and electric trains. Power-energy lithium-ion battery packs emerged with the advent of plug-in hybrids. It requires high energy storage in the battery, which can support...
