Source: According to the new energy vehicle promotion application recommended model catalog (6th batch of 2019) 2 Materials system: Ternary and lithium iron phosphate proportionally relatively stable in June three-yuan material installed capacity of 4.

77 g Wh, up one year-on-year. 78 times, up 24.9% from the previous month.

Compared with other materials, the three-yuan battery has increased significantly, and the rise is reduced.. The lithium phosphate ion battery has a load of 1.

70 g of, a year-on-year increase of 49%, a ring-percentage of 16%; a lithium titanate ion battery loading is 78.18mWh, a year-on-year increase of 4.11.

3%. The lithium manganese acid is 66.54mWh, up 23% year-on-year, down 44.

77% from the previous month.. Lithium manganate and lithium titanate ion batteries are used in commercial vehicles.

Lithium iron phosphate, lithium titanate, lithium manganganate ion battery is used in the commercial vehicle field, so the above materials are generally fluctuated in general and the production of commercial vehicles. Source: The number of certificates for the whole vehicle; analysis: Electric vehicle observers are used, the pure electric passenger car loader of three-yuan materials is the highest, up to 66%. The puller passenger car loaded with the three-yuan battery material continued to decline, only 193.

27mWh in June, decreased by 2% from the previous month; pure electric passenger car rose to 4.34GWH, up 27% from the previous month. In addition, the dedicated car ring loaded with a three-membered material battery is rapid, but due to the small base, the loader is only 2.

%, It is difficult to become mainstream. On the lithium iron phosphate ion battery, the pure electric passenger car and the passenger ring rose faster, up 19% and 10% respectively..

However, the phosphate ion battery pure electric passenger car installed machine accounted for 4% of the total, the market share is still small; pure electric passenger car, installed accounts for 15.2%. The lithium-ferrous ion battery is important to load in the commercial vehicle area.

Although in June reaches 200% in the passenger car field, since the base is very small, it accounts for almost negligible in the total assembly machine.. Source: “Electric Car Observer” According to the full car factory certificate statistics 3 battery packages: square battery accounts for rising, cylindrical, soft bag sharply lowered “electric car observers” according to the full car factory certificate, 2019 in the first half of 2019 Square batteries accounted for 82.

0% of the total assembly machine, this data was 73.6%; the soft boiled battery was 9.1% in the first half of the year, and the data in 2018 was 13.

9%; cylindrical battery The proportion is 12.5% ​​in 2018, dropped to 8.9% in the first half of the year, and the soft bag and cylindrical market share are declining.

. Under the promotion of domestic electric vehicles, especially the promotion of small electric vehicles, 18650 batteries have experienced a wave of climax. In 2016, nearly 20 18650 battery automatic production lines have been added.

. In 2018, the typical company produced 18650 power lithium battery has Shenzhen Bike, Far East Foster, Zhejiang Tianneng, Hengdian East, Life Battery, etc..

As the national subsidy policy is getting higher and higher in energy density of dynamic lithium battery system, the 18650 short board has gradually becoming. Under the driving of the electric motor industry, the power lithium battery is also rapidly developed, and there is a battery that has a lower cost and higher energy density..

TSLA also abandoned 18650 battery. On January 4, 2017, TSLA announced that the new 21700 battery started from the Panasonic joint research and development..

Mask said in social media that 18650 battery is completely a historical accident. It is the standard of early products. Now there is only 21700 battery to meet the requirements of electric vehicles on battery performance.

. In 2019, domestic battery companies, the new energy of the slings, Dongguan Zhenhua, Dongguan Chuangqing and other important supporting 18650 battery companies have not appeared in the whole vehicle factory certificate..

In China, Jianghuai has all been replaced with 21700 batteries, and the new version of the G3, which has given up the 18650 battery that has been used, and changes CATL’s square batteries.. Source: “Electric Vehicle Observer” is related to the cylindrical battery according to the total number of passengers, the square battery structure is simple, and the number of batteries is small, the energy density is relatively low.

. Compared with the cylindrical and squares, it will only be able to explode because of its outer packaging of aluminum plastic materials. Therefore, the safety performance is better, and the weight is also lighter.

. Its shape can be customized according to the demand, can be ultra-thin, or a cylindrical square or a triangle, etc..

Related to square and cylindrical, soft bag lithium battery capacity, smaller internal resistance, longer life, and in general, soft-package lithium battery performance is better. However, the soft-package lithium battery is currently less model, and the development cost is higher..

These also temporarily limit the development of soft boiled lithium batteries. (over).
