Demand For Lithium-ion Batteries In China's Electric Vehicle Market

Demand for Lithium-ion Batteries in China's Electric Vehicle Market

In 2017, the production and sales of electric vehicles in China exceeded the 770,000 mark. Among them, the domestic electric vehicle products achieved 33.62 GWh for lithium ion batteries (slightly higher than the 33.55 GWh we released before, mainly a product that had missed the assembly of CATL batteries), which increased by 21.24% year-on-year. Unlike the overseas market, which focuses on the development of electric passenger cars, China's market is that electric passenger cars, electric buses and special electric vehicles go hand in hand, which makes the battery installed capacity grow rapidly. From the vehicle category, pure electric passenger cars ranked first with 12.77GWh, accounting for 37.98%; pure electric bus battery installed 12.36GWh, accounting for 36.76%, ranked second; the other three types of vehicles combined installed 8.5GWh, accounting for 25.28%.

According to the battery technology route, lithium iron phosphate batteries account for 48.66% of the total installed capacity of 16.36 GWh, which is the biggest difference from the overseas market. Among them, 69.81% of lithium iron phosphate batteries are used in the field of pure electric bus and 18.36% in the field of pure electric passenger car. At present, only China insists on the lithium-ion battery line. With the bankruptcy of A123 system company and the decline of Valence, there is no battery manufacturer in the United States who advocated this line. From another point of view, the application of lithium iron phosphate batteries on such a large scale has also made it difficult for the Chinese government to achieve the target of 300 Wh/kg of automobile batteries by 2020. However, the installed capacity of lithium iron phosphate batteries in China is also decreasing. In 2017, the installed capacity of lithium iron phosphate batteries in China decreased by 22.84% compared with 2016.

NCM ternary battery installed in 2017 was 14.93 GWh, accounting for 44.39%, of which 61.93% was used in the pure electric passenger car market, 27.47% in the pure electric vehicle market, a total of 89.40%. Since Zhang Xiangmu, Director of Equipment Department of Ministry of Industry and Information Technology, verbally issued a ban on the use of ternary batteries for pure electric buses in early 2016, ternary batteries installed only 35.18MWh in the market of pure electric buses, very few of which were lifted in 2017, but it is difficult to improve. Lithium titanate battery has low energy density, but it has the characteristics of fast charging and discharging speed and long cycle life. It has application value in some specific markets of electric bus. It was installed at 534.49 MWh in 2017.

In the first eight months of 2018, lithium-ion batteries were installed in China's electric vehicle market at 23.50 GWh, an increase of 92.47% over the same period last year.

In the first eight months of 2018, the largest installed capacity was pure electric passenger car market, with 12.75 GWh accounting for 54.24%, more than half; pure electric bus ranked second with 6.95 GWh accounting for 29.56%, and the gap with the first was widening. PHEV passenger cars ranked third with 1.87GWh, accounting for 7.97%, EV special cars ranked fourth with 1.74GWh, accounting for 7.39%, and PHEV buses ranked last with 197.71 MWh.

In the first eight months of 2018, NCM accounted for 60.03% of 14.11 GWh, ranked first, LFP accounted for 37.46% of 8.80 GWh, ranked second, LMO accounted for 1.93% of 452.94 MWh, ranked third, LTO accounted for 0.58% of 135.43 MWh, ranked last. The installation of ternary batteries in 2018 was significantly better than that in the same period last year, reflecting the rapid dominance of ternary routes.

In terms of monthly installed capacity, more than 40% of the total installed capacity of batteries in 2016 and 2017 were achieved in the next two months: 13.96 GWh in the second two months of 2016, accounting for 50.33% of the total installed capacity in the whole year; 14.88 GWh in the second two months of 2017, accounting for 44.26% of the total installed capacity in the whole year. Due to the transitional period of several months this year, the loading situation in the first few months of this year is obviously better than that in the same period last year. If a transition period of several months is to be returned next year, the latter two months of this year will be better, and the phenomenon of rush-loading will be alleviated.
