Information

Most battery companies are developing NCM lithium battery because ofthe policy support for new energy vehicles with long range and high density batteries. Interest in lithium iron phosphate battery has picked up againafter the Chinese government began to reduce subsidies for new energyvehicles in mid-2019 and the frequency of accidents in NCM lithium battery vehicles.

 

The current domestic electric cars popular choice is NCM lithium battery,compared with lithium iron phosphate batteries,which have a higher energy density and basic can achieve 240 wh/kg, more than 180 wh/kg lithium iron phosphate energy density. However, the safety of ternary lithium battery is not as good as that of lithium iron phosphate battery due to its active material and low ignition point, and the cost of lithium iron phosphate battery is lower than NCM lithiunm battery.

 

It is understood that by the end of 2019, the domestic NCM lithium battery pack unit price is 1.05 RMB /Wh; The unit price of lithium iron phosphate battery pack is 0.8 RMB /Wh. If tesla uses a lithium iron phosphate battery this time, the cost will be about 10% lower than tesla's currentbattery. A cheaper battery pack is also expected to cut tesla's price by nearly 30,000 RMB. According to the data calculation, lithium iron phosphate battery can be about 20% cheaper than NCM lithium battery.

 

China is the world's largest market for new energy vehicles, and the revival of lithium-iron phosphate batteries may indicate that it is difficult for battery technology to make a rapid leap to the next stage, or whether Chinese companies will face more competition, although the renewed interest in lithium-iron phosphate batteries may not last long.

 

Although lithium iron phosphate battery has strong comeback, but the future focusing of lithium battery must not only stop here, as a stage of the development of lithium battery, lithium iron phosphate battery can succeedat the inflection point, which remains to be seen.
