The energy density of the battery supporting system of the second batch of recommended models from the beginning to the bottom increased significantly

In the first list of recommended new energy models, ternary batteries accounted for 38%, followed by lithium iron phosphate batteries accounting for 30%. Among the 201 new energy vehicles with matching power batteries, lithium iron phosphate batteries ranked first with 49% of the total.

On March 1, the Ministry of Industry and Information Technology (miit) released the second batch of recommended models for promotion and application of new energy vehicles in 2017. A total of 201 new energy models were listed in this catalogue, including 36 new energy passenger cars, 128 new energy buses and 37 new energy special vehicles. It is worth noting that the energy density of the battery system in the second batch of recommended models has been significantly improved compared with the energy density of the battery system in the first batch of model catalogs.

Among them, the performance of lithium iron phosphate battery in supporting quantity and energy density improvement of battery system is exceptionally excellent. The specific situation is as follows:

1. The supporting number of lithium iron phosphate battery exceeds the three-way battery to become the main force

According to the statistics of high-tech lithium grid, in the first batch of new energy recommended vehicle list, the ternary battery accounted for 38%, followed by the lithium iron phosphate battery accounted for 30%. Among the 201 new energy vehicles with matching power batteries, lithium iron phosphate batteries ranked first with 49% of the total.

2, the new energy bus adhere to the lithium iron phosphate position, but has emerged three battery vanguard

In terms of segmentation, in the field of new energy passenger vehicles, 24 battery sets have become the first to occupy the main advantages. Under the requirements of the new subsidy policy, the market share of three-way batteries in passenger cars will continue to rise.

In the field of special vehicles for new energy, 24 battery sets become the first.

Lithium iron phosphate battery in passenger vehicles and special vehicles in the field of less, but in the new energy bus field occupies an absolute advantage. It is worth noting that after the release of the "sanyuan lifting ban", the figure of sanyuan battery appeared for the first time in the field of new energy buses. Among 128 new energy buses, three models are equipped with sanyuan battery.

3, lithium iron phosphate battery system energy density of 120wh/kg supporting number is far more than the ternary battery

The new subsidy policy links the amount of subsidy with the energy density of the battery system. The higher the energy density, the more the subsidy will be. With the advantage of higher energy density, the three-way battery is favored by many car companies and battery manufacturers. After the battery enterprises transformed the production process and improved the properties of positive electrode materials, the energy density of the battery system for the second batch of new energy vehicles was significantly improved.

Among them, there are many types of lithium iron phosphate batteries whose energy density is much higher than that of ternary batteries. There are 44 types of lithium iron phosphate batteries above 120wh/kg, while there are only 4 ternary batteries with 120wh/kg.

Among the finalists, 29 battery systems with energy density of 90wh/kg-120wh/kg accounted for 80.5%. There are 4 types above 120wh/kg, which can enjoy 1.2 times new energy subsidy. All of them are ternary batteries, accounting for 12%.

Among the short-listed new energy buses, there are 5 models with battery system energy density of 85wh/kg-95wh/kg. There are 22 types of 95wh/kg-115wh/kg; There are 54 types with 115wh/kg or above, which can enjoy 1.2 times new energy subsidy, and 44 types with 120wh/kg or above, all of which are lithium iron phosphate batteries.
