Ternary lithium battery materials classification is analysed

Source: 2020 - 04 - 02 'hits: ternary lithium battery materials classification, ternary lithium batteries gradually become mainstream lithium batteries ternary classification, ternary lithium batteries gradually become the mainstream. The positive data of the lithium ion battery has a lot of kinds, according to difference of the positive data, can be divided into lithium cobalt oxide, lithium manganese acid, three metadata, and lithium iron phosphate lithium titanate. Era is quietly ternary lithium battery, battery companies are to grasp the market trends and opportunities, to speed up the pace of adjustment, so as to promote the rapid development of its own. Ternary lithium battery with high energy density, good safety and stability, excellent electrochemical properties, such as support for high rate discharge, and moderate cost advantage of prices, consumer digital electronic products, industrial equipment, medical equipment and other primary and secondary lithium batteries has been widely used. Ternary polymer lithium battery is the use of nickel and manganese acid gel polymer electrolyte of lithium battery made of three yuan positive data. The electrolyte as a transmission medium, the ion movement generally consists of solvent and lithium salt. Lithium secondary battery electrolyte is mainly composed of liquid electrolyte, ionic liquid electrolyte and solid polymer electrolyte and gel polymer electrolyte composition. Its biggest advantage is that gap has high mechanical strength, film provides a large surface area. The thinner film, the higher energy density, because more active substances can be embedded in the battery. Dynamic ternary lithium battery refers to the battery support high power high discharge current, high power density, releasing energy in unit time. Multiplier discharge refers to add charge multiplier, multiplier and discharge the battery adhere to certain capacity. The charging and discharging rate shows that using xC 1 c said nominal capacity of battery can use down in 1 h, while using the rate of 2 c can be used after 30 min. Ternary power lithium batteries, and now most of the research, the old skill is Japan panasonic, can end 30 c discharge test stage, during this period has been successful over the commercial mass production of 18650 type 12 c ternary lithium battery discharge rate, the capacity is 3300 mah. Low temperature properties of lithium batteries from the low temperature discharge properties and cycle life, low battery is the most important thing is to insist on the conditions of low temperature materials liquidity, so the flow between the positive and negative electrode of lithium ion can be carefree, the end of the battery charging and discharging. Ternary lithium battery manufacturers at home and abroad to do - in its roots 20 degrees discharge temperature and discharge capacity of more than 50%, cycle life is controlled in 400 times, can meet the general electric and electric field. In recent years, with the rapid rise of the new energy automobile market, our country electric power lithium battery market has been rapidly expanding. Ternary material lithium ion battery has high voltage mode of vibration, high energy density, high density, good electrochemical stability, circulation features, such as the increase of new energy car journey of life, reduce user significantly superior to the concerns of the journey of life, but also has high discharge voltage, output power, low temperature performance is good, can be used for 24 hours of interests, such as temperature gradually accepted by automobile manufacturers and users. 1, in all of the old electric vehicle power lithium batteries, the ternary lithium battery energy density is the biggest, other lithium iron phosphate, lithium titanate is hard to meet the requirements of state subsidies for electric cars. - In front of state subsidies, the ternary lithium battery is the best choice; 2. From the point of customer expectations of extended travel, ternary lithium battery has a large energy density, in the same situation can be further extended trip; 3. The ternary lithium battery unit KWH ( Yuan/KWH) Lithium iron phosphate and titanate is obviously better than the lithium battery. Price is the king of products to survive; Four, the ternary lithium batteries better performance at low temperature. Compared with the lithium iron phosphate batteries, low temperature properties of ternary lithium battery has obvious advantages. Under the specific requirements and policy guidance, the ternary lithium batteries gradually becomes the new energy vehicles on the market of choice. In new energy passenger vehicles and special vehicles, ternary lithium battery market in China did not stop the pace of development, adhere to do at a high speed.
