Analysis of advantages and disadvantages of lithium-ion automotive batteries
Lithium-ion car battery is a kind of car battery products produced for the use of lithium-ion battery functions, lithium-ion car batteries have a wide range of use, generally used for automotive motors and related automotive electrical appliances, etc., more electricity consumption, in addition to the use of cars, Lithium-ion automotive battery is a kind of battery widely used in electric vehicles, hybrid vehicles and other new energy vehicles. Compared with traditional lead-acid batteries, lithium-ion batteries have the advantages of higher energy density, longer service life, lighter weight and smaller volume.

      Automotive battery, also known as battery or storage battery, is an important part of the car. Its main role is to provide a strong starting current to the starter motor when the engine starts, and to assist the generator in supplying power to the electrical equipment when the generator is overloaded. The car battery also powers the electronics when the engine is idle. In addition, the car battery is a high-capacity capacitor that protects the electrical appliances in the car. The working principle of lithium-ion batteries is mainly to use the embedding and separation of lithium ions to achieve the storage and release of electrical energy. In the charging state, lithium ions are separated from the positive electrode material by the electrolyte through the diaphragm and embedded in the negative electrode material; In the discharge state, the lithium ions are separated from the negative material and returned to the positive material through the diaphragm again. Across the electrodes in the process, the potential difference between the generate electricity,

& have spent Under normal circumstances, the car battery is generally replaced every 3 to 5 years, it is recommended that the owner detect the internal resistance and voltage of the battery during each maintenance, if the internal resistance and voltage do not reach the specified value, it means that the battery needs to be replaced. If the internal resistance and voltage do not reach the specified values, the battery needs to be replaced. In addition, the shelf life of car batteries is usually one year or 20,000 kilometers, but it is possible that some product quality is still in normal condition after the shelf life, so there is uncertainty. In order to ensure the normal use of the car battery and extend its service life, the owner needs to pay attention to timely replacement of the battery, and follow the corresponding instructions and safety specifications. For example, when starting the engine, avoid starting it repeatedly to reduce the battery load; Before stopping, turn off the car electrical equipment and then turn off the engine; Periodically check whether battery connection lines and piles are loose or corroded, and clean and tighten them in time.


    From the perspective of some technical problems of lithium-ion batteries, the cathode material of lithium-ion batteries is usually lithium compounds, such as lithium cobalt, lithium manganese, lithium iron phosphate, etc.; The anode material is usually carbon material such as graphite. Electrolyte is a very critical part of lithium-ion batteries, usually using organic solvents to dissolve lithium salt solutions. The advantages of lithium-ion automotive batteries are high energy density, long life, lightweight and miniaturization, so they have been widely used in the field of new energy vehicles. At the same time, with the progress of technology and cost reducing, lithium ion battery is becoming more and more widely applied in other fields,

& have spent However, lithium-ion car batteries often have some drawbacks, such as safety issues and unstable performance at high temperatures. Therefore, when using and handling lithium-ion batteries, please pay attention to safety and follow the relevant regulations and guidelines. But in general, lithium-ion automotive batteries are an important new chemical power supply, with a wide range of applications and huge market potential. Along with the advance of technology and the reducing of the cost, it will play a more and more important role in the field of new energy vehicles,
