Lithium Batteries Knowledge
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.
Why can't the ternary lithium battery be fully charged? Advantages and disadvantages of ternary lithium battery
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.
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.
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.
Explain the difference between power lithium-ion batteries, capacity lithium-ion batteries, and consumer lithium-ion batteries
There are many types of lithium ion batteries, including power lithium ion batteries, capacity lithium ion batteries, and consumer lithium ion batteries. Power-type lithium-ion batteries and capacity-type batteries differ in materials and processing techniques. The difference in discharge characteristics means that the range of use of the two is quite different. When purchasing a Li-ion battery pack, be sure to differentiate between the two to prevent adverse effects on the load.
What is a sodium-based battery? The difference between sodium-based batteries and lithium-ion batteries
A sodium-based battery is one that combines sodium with a compound called inositol. Developed by researchers at Stanford University in October 2017. The sodium in the new battery binds to a compound called inositol, an organic compound commonly found in household products, including infant formula. Just as sodium is much more abundant than lithium, rice furfuryl alcohol is easily extracted from rice bran and can also be found in by-products produced during corn processing.
Lithium iron phosphate battery refers to a lithium ion battery that uses lithium iron phosphate as a positive electrode material. The cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium manganate, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium cobalt oxide is the cathode material used in the vast majority of lithium-ion batteries. In terms of material principle, lithium iron phosphate is also an intercalation and deintercalation process, which is exactly the same as lithium cobaltate and lithium manganate.
When many materials in a lithium battery come into contact with water, a violent chemical reaction occurs, releasing a large amount of thermal energy, which generates heat and burns. The manganese dioxide in the positive electrode of a lithium battery can generate heat with just a small drop of water. When the sulfurous chloride in the lithium battery comes into contact with water, it releases heat energy and produces hydrochloric acid and sulfur dioxide at the same time. If the temperature is too high, it is not normal. The reasons may be as follows:
In daily life, some wrong behaviors are easy to become habits, and over time, various problems will appear, such as the incident of "forgetting to unplug the charger and burning the house". There are actually many misunderstandings about the fact that we have to charge our mobile phones every day. Maybe 99% of people use the wrong method to charge their mobile phones every day. Come and see if you are.
Lithium battery equipment is mainly used in each process link of lithium battery production process. Lithium battery materials are mainly composed of four materials: positive electrode material, negative electrode material, separator and electrolyte, in addition to packaging and other parts. Lithium battery equipment is the necessary equipment and infrastructure for the lithium battery manufacturing industry.
