Mainstream electric vehicle battery analysis: about half of the amount are using ternary lithium-ion battery

According to a Polaris distribution network dispatch: Power battery has been regarded as the most important link in the development of electric car. Currently, lithium-ion battery anode material is mainly using cobalt acid lithium, ternary material, lithium iron phosphate and lithium manganese acid, etc. Inventory of eight enterprise 13 cars on sale, there are 6 models using ternary lithium-ion battery, and they were mainly launched in 2014 and beyond. lithium iron phosphate battery still account for half, and manganese lithium iron phosphate, manganese acid lithium batteries are also applied.

BYD: lithium iron phosphate, iron phosphate lithium manganese

Before entering the car manufacturing, BYD is committed to the r&d and production of battery products, this to the development of BYD new energy vehicles provides a unique advantage. The e6, qin, electric buses, holographic products such as car batteries are all their production.

E6 is the longest range in the domestic electric car models, carry 63 KWH of lithium iron phosphate batteries, range of 300 km. Currently BYD lithium iron phosphate battery energy density of about 130 wh/kg, less than the density of ternary material, therefore BYD in the car loaded with a large number of cells, to increase the range. The advantage of stability and durability, lithium iron phosphate e6 taxis run in the actual performance to prove: since 2010 has been put into operation in Shenzhen 850 e6 electric taxi accumulative total mileage of nearly 300 million km, bike maximum mileage of 670000 kilometers.

lithium iron phosphate were the main battery BYD new energy vehicles take route, BYD has improved under the condition of the research route of lithium iron phosphate, iron phosphate lithium manganese. Newly released the fourth batch of new energy vehicle purchase tax free directory, according to the new e6 will launch new iron phosphate lithium manganese battery, range up to 400 km. Although 19 KWH battery capacity increased, but the overall battery quality weight 50 kg. Through the adoption of manganese lithium iron phosphate batteries instead of phosphoric acid iron battery, battery energy density increase, in the form of "incremental don't gain weight" obtain the range increase greatly.

Daimler also took a fancy to BYD's battery technology, the cooperation of its potential electric car USES BYD lithium iron phosphate batteries, new car in less than a year, but the battery life, stability, etc., can see the performance of the e6. Teng potential carrying 47.5 kWh battery, a comprehensive range of more than 250 km. If BYD will adjust manganese lithium iron phosphate as the main direction of the battery, the future may also carry on Teng potential models’ application, further improve the range.

Saic: lithium iron phosphate, hydrogen fuel cells

Saic roewe E50 pure electric vehicles using lithium iron phosphate batteries, provided by the Shanghai jie new battery systems co., LTD., the company by the Shanghai and A123 joint venture, E50 carrying 18 KWH battery, a comprehensive range of 120 km, compared with most electric cars on the market, range obviously disadvantaged. Since its launch in 2012, saic has not to upgrade this fine car, coupled with higher price, E50 sales only more than 400 vehicles last year.

Compared with the pure electric vehicles "stop", saic seems to be more focused on the development of fuel cell vehicles. Is saic roewe 950 plug-in fuel cell car research and development of the fourth generation of fuel cell vehicles. Saic take is the plug-in path of fuel cell technology, in addition to the fuel cell stack with an electric motor. The car battery can reach 400 km, hydrogenation only for 3 to 5 minutes, can start - 20 ℃ below zero temperature environment, also has the external power generating function, through the plug converter, can be realized for other appliances including electric car charging function.

Beijing new energy's first electric car E150EV USES is the lithium iron phosphate batteries, middle to upgrade, battery from 21 kWh to 25.6 kWh, a comprehensive range of 160 km. At the end of last year, Beijing new energy released a new generation of electric vehicles EV200 and ES210, started using ternary lithium battery.EV200 models carrying 30.4 kW ternary lithium battery, working condition of comprehensive range of 200 km;ES210 carrying 38 KWH lithium-ion battery, a comprehensive range of more than 175 km. Beijing new energy that is used by yuan battery provided by Beijing electronic control ace open technology co., LTD. (baic) in collaboration with SK, officially announced after the battery full put more than 3000 capacity attenuation rate is less than 20%.

Although three-yuan battery development momentum is very fierce, but Beijing new energy didn't give up the lithium iron phosphate battery, this year's new EV160 equivalent EV200 another battery version, in addition to battery types, appearance and configuration. EV160 carry 25.6 kWh of lithium iron phosphate batteries, a comprehensive range of 160 km. Battery is provided by ATL pride, this is Beijing earlier established cooperation with ATL battery company. According to the Beijing new energy production of January to April, the EV series model and ternary lithium iron phosphate lithium models share proportion is close to 1:1, consumers quickly accepted the ternary lithium models.

Jianghuai: lithium iron phosphate, ternary lithium

Jianghuai iEV4 and former three generations of the electric car adopt the lithium iron phosphate batteries (a total of more than 8000 vehicles), supplied by the porch tech center. IEV4 carry 19.2 kWh battery, the range of 160 km.

On the new generation of electric cars iEV5, jianghuai started using aluminum nickel and cobalt ternary batteries, supplied by Tianjin lishen. Load 23 KWH battery iEV5 battery can reach 200 km. Whether range, speed, configuration, etc., iEV5 are far ahead of the fourth-generation models, and subsidies for control within 90000-yuan, high cost performance. Using the ternary material can be between the "range" and "cost" for good balance. IEV5 listed a month or so, sales volume has more than 500 vehicles.

Qichen morning breeze: lithium manganese acid

Qichen morning breeze is the Chinese localization based on Nissan leaf electric cars, with the help of the Nissan mature lithium battery technology. Morning breeze electric cars using manganese acid iron battery, composed of 192 pieces of battery monomer battery pack, the total weight less than 200 kg. With a comprehensive range of 170 km. With the lithium iron phosphate, cobalt acid lithium, Batteries ternary material Compared with manganese acid lithium battery have advantages also have disadvantage. Manganese acid lithium energy density, thermal stability and cost center, some relatively poor thermal stability. Qichen chenfeng using natural air cooling, and the solidification of liquid electrolyte, through the electrolyte change electronic movement speed, prevent the battery temperature is too high.

Geely (know beans): ternary lithium, lithium iron phosphate

Geely and new ocean cooperation production of bean electric vehicles have a ternary lithium and lithium iron phosphate battery two versions, know beans D1, D2, ternary lithium version is carrying 15 KWH battery, range of 150 km. D1 know beans edition of carrying 12 KWH battery, lithium iron phosphate range of more than 80 km.

Chery: ternary lithium

Chery currently popular high-speed lithium electric cars were in the "arms" the ternary lithium and eQ models carrying 22.3 kWh battery, a comprehensive range of 170 km, the battery by Zhejiang wanxiang million to provide power company. Chery in 2010 launched a wenqi M1EV electric car, carrying the lithium iron phosphate batteries, but now has been largely discontinued.

Zhongtai: ternary lithium

Zhongtai cloud 100 load 17.76 kWh ternary lithium batteries, the range of 150 km. Similar to chery, zhongtai old 5008 ev, M300EV basic production of electric cars, the future will launch a new electric car sesame E30, E200A and E200B are likely to turn to the ternary lithium battery.

Power battery technology is still in the continuous development and progress, a few years ago the lithium iron phosphate battery is popular for long service life, good safety features, but with safety problems of ternary lithium battery gradually improved, the advantages of high energy density is drawn on, more and more enterprises and car models will use ternary lithium battery. In future, if graphene battery, aluminum air battery is used, power battery and electric vehicle industry will be change.
