BYD may launch the first SUV equipped with ternary lithium batteries

BYD is China's new energy vehicle giant, and the lithium iron phosphate batteries that have been used in electric vehicles are cheap and high-quality, and have been well received
by the majority of users.
A few days ago, BYD insiders revealed that the company is constantly replacing existing technology, focusing on ternary materials, and the plug-in hybrid SUV "Song" that will soon be listed may become BYD's first model
equipped with ternary lithium batteries.

Lithium iron phosphate batteries were first invented
in 1997 by the research group of Professor John Goodenough of the University of Texas.
Lithium iron phosphate batteries have the advantages of safety, high stability, environmental protection, non-toxic raw materials and cheap price, but there are also problems such as
poor conductivity and low density.
With the research in recent years, the defects of conductivity have been solved by adding conductive agents, but there is no good solution
to the problem of large volume.

After years of hard work, BYD is currently in a leading
position in lithium iron phosphate battery technology.
However, since 2014, the domestic lithium battery cathode material industry as a whole has shown a trend
of transfer to ternary materials.
Compared with lithium iron phosphate batteries, ternary lithium batteries have longer endurance, characterized by high energy density, good low temperature performance, high reliability, long life, etc.
, but the cost is high
.
Some analysts believe that with the gradual maturity of the safety of ternary lithium batteries in the power field and the increase in the demand for cruising range in the consumer market, domestic car companies may set off a round of lane change from lithium iron phosphate to ternary routes
