Lithium iron phosphate is super lithium ternary

Ternary lithium batteries are at a disadvantage

The competition of automobile power battery fluctuates several times under the big stick of new energy financial subsidy policy. First ternary lithium batteries knocked lithium iron phosphate batteries out of the "iron throne", and now it is the turn of lithium iron phosphate batteries, ternary lithium batteries in the underdog.

Industry statistics show that the market share of lithium iron phosphate batteries reached 69 percent in 2016, but fell sharply to 32 percent in 2019.At the same time, the market share of ternary lithium-ion batteries soared from 27% to 65%.But in just over a year from 2020, lithium iron phosphate batteries have made a comeback.

In 2020, the vehicle load of ternary lithium battery totaled 38.9GWh, accounting for 61.1% of the total vehicle load, with a year-on-year decline of 4.1%.The total loading volume of lithium iron phosphate battery was 24.4GWh, accounting for 38.3% of the total loading volume, with a year-on-year growth of 20.6%.Entering 2021, the trend of recovery of lithium iron phosphate batteries is increasingly obvious, and the growth rate of its output and installation is much faster than that of ternary lithium batteries.

The lower cost, better safety of lithium iron phosphate batteries become the first choice of oems

In the tug-of-war between ternary lithium batteries and lithium iron phosphate, in addition to the factors of policy subsidies, the differences in physical properties of the two batteries have also been discussed. 

According to the latest data released by China Automotive Power Battery Industry Innovation Alliance, the loading volume of domestic power batteries in July was 11.3GWh, of which ternary lithium batteries totaled 5.5GWh, up 67.5% year-on-year and down 8.2% month-on-month.A total of 5.8GWh of lithium iron phosphate batteries were loaded, up 235.5% year on year and 13.4% month on month.

This is after this May this year, the monthly output of lithium iron phosphate battery was the first super three yuan lithium battery in the past three years, and the monthly loading volume also exceeded three yuan lithium battery for the first time in the past three years, realizing the double surpass of monthly output and loading volume.

If the time line is extended, from January to July, the total loading volume of terene lithium battery is 35.6GWh, accounting for 55.8% of the total loading volume, up 124.3% year-on-year.The loading volume of lithium iron phosphate battery was 28.0gwh, accounting for 43.9% of the total loading volume, up 333.0% year-on-year.Although in terms of installed capacity and market share, lithium iron phosphate battery still lags behind ternary lithium battery, but in year-on-year growth rate, lithium iron phosphate battery is more than 200 percentage points higher than ternary lithium battery.

In terms of output, the market share and year-on-year growth rate of lithium iron phosphate batteries have exceeded those of ternary lithium batteries.From January to July, the total output of ternary lithium battery was 44.8GWh, accounting for 48.7% of the total output, with a year-on-year growth of 148.2%.The total output of lithium iron phosphate battery was 47.0gwh, accounting for 51.1% of the total output, with a year-on-year increase of 310.6%.
