Why is the ternary battery industry direction

Ternary battery has been as the mainstream of power battery industry development direction, but still there is a dispute in the industry, in this chapter, we will analyze why we firmly believe that the ternary batteries must be the determination of industry development direction. 1. Ternary battery has become the mainstream industry according to we take part in many professional technology BBS, and communicate with people in the industry, the lithium battery has become the mainstream of the current power battery, and three yuan battery is the mainstream line of lithium battery. Below is a summary in the path of the current power battery technology, the industry mainstream battery manufacturers have to choose three yuan as the mainstream of the development of nearly three years. In the next generation of batteries before maturity, ternary cell is the best solution. 2. Horizontal comparison: three yuan battery obvious advantages in fact why three yuan is the mainstream line, also need to use Numbers to illustrate. First, we will be three yuan compared with other technical route power battery batteries, contains the now commonly used lithium iron phosphate, manganese acid lithium, lithium titanate, etc. , you can see three yuan batteries have the advantages of: the highest energy density, ease range anxiety ( The core elements) High discharge voltage, the output power of low temperature performance is good, adapt to the climate in the north, of course, three yuan is the disadvantage of battery cycle life is too short, poor thermal instability. But this can be used to increase the battery capacity and improve the battery system design to improve it. For passenger car range anxiety and all-weather use problem, only three yuan batteries can meet the requirements, so we conclude that the ternary batteries must be the most suitable technical route passenger cars. 3. Longitudinal comparison: system itself has huge potential in this paper from the longitudinal comparison ternary cell of a lot of advantage, and from the point of system, ternary battery also has great potential for mining. At present three yuan battery maker is the main application of battery, 333 and 523, 622 only part manufacturers use. As the material system, high nickel battery maker will begin next year the domestic three yuan 811 and NCA material application, monomer battery energy density from 250-200 wh/kg 300 wh/kg. Domestic status: 523 application more, 622 start application part of the battery manufacturers, next year is expected to start using 811 and NCA status abroad: basically 622811 applicable, panasonic for tesla's NCA overall trend: high nickel, is to improve the energy density and stability decline the solution: 1) The progress of the material and process; 2) The progress of the system design 4. International manufacturers: total to three yuan battery again from the point of practical application situation of car companies, classification statistics can be seen from the table below, the current international mainstream makers have basic comprehensive backward ternary cell line. Besides tesla insist on using NCA, Japanese and Korean companies mainly used the sliding material, manufacturer, and mainly A123 lithium iron phosphate route but A123 ternary soft package products have also been introduced, the future will implement the technical route of the switch. For several main technical route of contrast, summarized as follows: sliding: Japan and South Korea manufacturer's overall layout NCA: panasonic + tesla to form industry alliance: lithium iron phosphate A123 advocate, but has begun to ternary lithium manganese acid: application more 5 major Japanese manufacturers. Domestic passenger car market ternary battery already occupy half again analysis domestic passenger car market, in the table below is our current market sales statistics system of all new energy car battery. In addition to byd, 002594). And saic, other manufacturers have entirely towards three yuan, especially pure electric vehicle parts, three yuan battery has occupied the absolute superiority. And according to the same plan, byd has begun on the PHEV vehicles' song 'start using ternary batteries, proportion is expected to further expand the application in the future. And saic also began to use three yuan on E50 battery at present, the future will be comprehensive transformation of the ternary cell line. As you can see, in the next two years the proportion of three yuan battery will gradually improve. 6. Industrial policy: don't say, but the body is honest for ternary cells from the Chinese government industrial policy, in the short term is very careful attitude and from earlier this year decided to suspend using ternary on passenger car battery, and then the battery catalogue reiterated that all of three yuan has bigger constraints battery industry. We believe that in the first half of the Chinese government restrictions on ternary battery for two things: 1) In the expenses have all of the events, unbearable safety accidents; 2) After the end of the explosive growth in the industry, industry also need to undertake rectifying to consolidate development base. But we believe that the government for the ternary battery limit is only temporary, the government's real attitude has been reflected in other ways: 1) In the subsequent subsidy policy for introducing 'battery system quality of', 'Ekg' and 't hundred kilometers energy consumption index, objectively in guiding the use of high energy density battery system; 2) Mr. Wan put forward over the next five years to double the power battery unit energy density, lower the manufacturing cost by 50%; Make the unit battery power reaches 300 watts or more at the same time, the cost dropped below $1. And lithium iron phosphate system theoretical energy density is 200 wh/kg, only completely impossible to achieve this goal, therefore, we believe that, as with the new energy automotive industry, the Chinese government attitude towards the ternary battery is support rather than suppressed, the future of industry policy is expected to guarantee under the premise of safety, continue to encourage the development of high energy density batteries.
