What is a ternary batteries

1. What is a ternary batteries in the past few in-depth report, we on new energy vehicles and power battery market has carried on the detailed calculation and prospect, results show that the industry is in an exciting start level, thus strongly recommend new energy automobile plate, and then quickly pull litre price we also verified the logic of industry growth. In this report, we will analyze the three yuan battery this subdivision plate, in order to demonstrate why ten times for we think that the industry will be out since then. 1. 1. Ternary battery for three main concepts of this term, investors should already be very familiar with, but may not be able to understand its meaning behind, this section is the first of three yuan explained some basic concepts of the battery. What is a ternary ternary battery is just a common says, more comprehensive call three yuan (should be ' Material) ( Lithium) Batteries', is essentially a kind of lithium battery, the formal name should be nickel cobalt manganese acid lithium ( NCM) Lithium nickel and cobalt aluminate ( NCA) 。 Usually we are in the anode materials for lithium batteries, such as lithium iron phosphate, lithium manganese acid and three yuan (such as battery Example: lithium titanate battery, named after the cathode) 。 Three technical route of lithium iron phosphate power battery ( 联赛 : the United States and Canada were the first to research and development of power battery technology, at present China many power battery manufacturers adopt LFP technology. Ternary system: mainly USES the NCA and sliding as the anode material, the battery energy density is high, but the cost is higher than the LMO battery, mainly on behalf of the manufacturer is SDI, SKI ( NCM) , panasonic ( NCA) In China, mainly lishen, bick, etc. Manganese series: mainly USES the LMO as the anode material, but usually after modification, and mix a small amount of sliding or LNO increasing battery energy density, mainly on behalf of the manufacturer is LGC, AESC, LEJ, etc. , mainly in China (citic guoan 000839). Unita solid. Ternary synergies Co: stable layered structure, improve the conductivity and improved charge-discharge cycle performance, but with the increase of Co content, materials of reversible intercalated-li capacity fell, the cost increase; Ni: upgrade the capacity of the materials of reversible intercalated-li, excessive Ni will worsen the cycle of material performance; Mn: improve security and material structure stability, reduce the cost of materials, spinel phase occurs Mn content is too high and damage of layered structure. 1. 2. Ternary classification for ternary battery, can be classified according to the positive electrode materials and packaging forms, and these two kinds of classification and can create more types of combination collocation. According to the anode material classification: mainly nickel cobalt manganese acid lithium ( Sliding, which according to the ratio of three elements can be divided into 333, 523, 622, 811, etc. ) Lithium nickel and cobalt aluminate ( NCA) And so on. Now is the main application of sliding 523 and 622811 has not been large-scale applications. NCA is now mainly used on tesla model. But the future trend of the system's high nickel is quite obvious. According to the way of packaging: usually divided into soft package, square, cylindrical ( 18650, 21700, etc. ) Again in three broad categories, each categories can be divided into different size of segment specifications. These three systems, the most mature type cylinder is 18650, can achieve automatic production, consistency is the best. Table 1: different power battery encapsulation type 1. 3. Ternary chart for ternary battery, battery industry chain with lithium battery before very close to the industry chain, the main difference in the anode material. In addition to the anode materials production technology has great different, its upstream need nickel, cobalt, manganese and other metal is don't need other lithium batteries. In addition, the ternary material of electrolyte, the diaphragm is process also need to improve to fit the new material system. Lithium-ion batteries, electric vehicles, lithium battery manufacturer, storage battery manufacturer scooter battery manufacturers, product by the supervision and inspection institute of guangdong province, through international CE certification, by the ping an insurance company of China national group, two years warranty, the first in the New Year.
