Power lithium-ion battery research: lithium-ion battery electric vehicle drive industry research reports




Trend of electric cars is inevitable. Automobile consumption as a social an important sign of improved living standards, in the aggregate control is unrealistic.

It is only through technology, exploration, search for alternative energy sources, reduce emissions, in order to ease the contradiction between demand for cars and environmental protection. The efficiency of pure electric vehicles can reach 3.9 times the regular gasoline cars, CO2 emissions can be reduced 2 / 3; hybrid electric vehicle can achieve 1.7 times the regular gasoline cars, CO2 emissions can be reduced about 1 / 2. In the foreseeable technological conditions, the trend of electric cars is inevitable.

The report focused on the lithium-ion batteries. The electric drive system of electric vehicles as the main components: power batteries (including battery management systems, charging systems), power inverters, drive motors (including motor speed control system). Advances in battery technology depends on materials science and other basic disciplines progress, technological breakthroughs difficult, but it depends on the promotion of electric vehicle battery cost has dropped significantly. Lithium-ion battery energy density is about 1.5-2.5 times the nickel-metal hydride batteries for lead-acid batteries 3-5 times as indicators of self-discharge was significantly better than nickel-metal hydride batteries, lithium-ion battery electric vehicle battery power will be the main technical line Therefore, we have electric vehicles in the first report of a thematic focus on lithium-ion battery.

The use of the cost of electric vehicles in 2020 is expected to reach with conventional cars quite. At present electric vehicles powered by rechargeable lithium-ion battery faster prices in the $ 1600/kwh about ordinary power lithium-ion battery prices in the $ 500/kwh, in accordance with the current U.S. gasoline and electricity price trends, in the car throughout the life cycle, 100km endurance capacity Quick charge lithium-ion battery powered electric cars using performance rather than the cost of gasoline internal combustion engine cars 25% higher. Once the electric vehicle battery power prices fell to $ 200-300/kwh, electric cars using the cost will be quite conventional cars. According to projections, the relevant policies in various countries, encouraged by 2020 the global demand for electric vehicles using lithium-ion close to 50Gwh, fast rechargeable batteries are expected to cost in 2020 dropped to $ 400-500/kwh, general power battery prices could fall to $ 200-300/kwh .

The promotion of electric vehicles will drive the growth in demand for raw materials downstream. Lithium-ion batteries are four main raw materials include: anode, cathode, electrolyte, separator.

Due to the different cathode materials, manufacturing costs account for about 30 ~ 40%, the negative electrode materials, accounting for about 15 ~ 20%, accounting for 15 ~ 20% of the diaphragm, electrolyte accounted for 5 ~ 10%, and other costs accounted for about 25%. We expect the Chinese electric vehicles in 2020's total car sales account for about 5.4%, PHEV is expected to become a major component of electric vehicles in 2020, accounting for 4.5% of total car sales. Electric vehicles in 2020 will reach 1.329 million, including HEV, PHEV, EV, respectively 13.5,109.5,9.8 million. In accordance with our model 2010 to-2015 Nian electric cars on the needs of cathode materials, respectively 347,970,1781,3507,5584,9432 t; in which the demand for lithium iron phosphate, respectively 31,165,563,1551,3084, 6123 tons. 2010-2015 pairs of anode materials for electric vehicle demand 162,434,740,1358,2025,3216 tons, respectively, for the needs of the electrolyte, respectively 135,362,616,1131,1687,2680 tons, the demand on the diaphragm 2429,6513,11094,20363,30368,48234 square meters, respectively.

Companies recommendation. Based on the company's core technology, the understanding, we recommend cathode materials technology is expected to win Shanshangufen (600,884), and lithium hexafluorophosphate may create a breakthrough in Jiangsu Guotai (002,091).
