The first time and undergoes a series of tests to demonstrate its quality and efficiency. The final stages of battery formation include precharging, degassing, and high-temperature aging. When that last phase is finished, the device is ready for use in different applications. Electric vehicles run on lithium-ion batteries. They are among the most popular types of batteries, mainly due to the fact that they allow you to travel more miles on a single charge compared to other types of batteries. Its manufacturing process is very similar to that of the most common lithium batteries. A characteristic feature of electric car batteries is that they constitute a series connection of several lithium-ion cells that make up so-called modules. Each module of a battery contains a few to more than ten cells connected in series. The modules are then soldered to form battery packs that undergo quality control. Raw materials for the production of batteries. The most popular energy storage systems include lithium-ion batteries. The production of these cells is complex and requires maximum quality at each stage. An important issue is to choose such raw materials for production that the finished battery can fully satisfy market demand and consumer requirements. Rails The most important raw materials for battery production include metals, mainly lithium, cadmium, nickel, iron, zinc and manganese.
The latter is the most popular material used to produce lithium-ion batteries. Other elements used for battery production are magnesium and aluminum (as electrodes), due to their high standard potential and electrochemical equivalent. An additional benefit is its relatively low price and high availability. This makes them an ideal replacement for the popular electrodes made of zinc. Another metal used in batteries CZ Leads is silver, which makes it possible to produce safe cells with a high energy density. In addition, the use of silver makes it possible to achieve a higher battery voltage compared to cadmium, for example. metal oxides Battery electrodes (cathodes and anodes) are not only made of metals. Metal oxides are also used, such as manganese (IV) oxide or zinc oxide. The active material in lithium-ion batteries is usually lithium, which most often occurs in the form of oxides combined with metals such as cobalt, manganese, nickel, vanadium or iron.
Electrolytes The electrolyte is the key component of lithium-ion batteries that allows free flow of electrons between the electrodes. Electrolytes are mainly aqueous solutions or solutions in organic substances, which are produced by dissolving one or more types of salt, for example, ammonium chloride, zinc chloride or magnesium perchlorate. In alkaline batteries, potassium hydroxide is used as the electrolyte. Vinylene carbonate is also commonly selected to produce electrolytes for lithium-ion batteries. It is especially important for the battery and accumulator sector, which is experiencing dynamic growth. High purity vinylene carbonate (minimum 99.99%) is available in the wide range of products of PCC Group , which is one of the leading manufacturers and suppliers of chemicals and raw materials for any industry. Graphite Graphite or powdered carbon is a key raw material for the production of electrodes. The structure of some batteries includes graphite rods that “collect” the electrons flowing from the circuit and distribute them across the cathode. In addition, the structure of graphite facilitates the extraction of gases produced during an electrochemical reaction. Plastic Plastics , such as polyethylene or polypropylene , are excellent materials that are applied in the production of battery separators. They separate the cathode from the anode. Plastics are also used to make battery casings and casings.
