Lithium iron phosphate battery energy density breakthrough or applied to passenger car field

For the current battery types, it is estimated that many of us will think that the most common one is button battery cr2032. I don’t know if you know that even lithium batteries are also divided into many categories. Now the editor of Science and Technology Landscape will tell you about the application of ternary polymer lithium batteries and lithium iron phosphate batteries in the automotive field!

Because the whole society is in a state of "excitement" for the development of new energy vehicles, everyone has started to develop it all at once. Because ternary polymer lithium batteries have the "first-mover" advantage in the field of passenger cars, basically all passenger car batteries now belong to ternary polymer lithium batteries, and lithium iron phosphate batteries are late, and now they have basically "fallen" to the marginal field of buses and logistics transport vehicles.

However, the more important reason is doubt. Compared with the high energy density of ternary polymer lithium batteries, the poor energy density of lithium iron phosphate batteries is the main reason. Now in the field of passenger cars, a range of more than 300 kilometers is very common, which is also the general energy density of ternary polymer lithium batteries with a single energy density of more than 200Wh/kg.

At present, the capacity density of lithium iron phosphate batteries is generally around 150Wh/kg. Even if it is better, it is around 160Wh/kg. Compared with the 200Wh/kg energy density of ternary batteries, there is a big gap.

However, this does not mean that lithium iron phosphate batteries have given up catching up with ternary batteries. Now our domestic companies have begun to develop energy densities at the three gradients of 180Wh/kg, 200Wh/kg and 220Wh/kg, and have obtained very good pictures. Now 180Wh/kg has started two games. Once it reaches a higher gradient, it means that lithium iron phosphate batteries have the opportunity to enter the passenger car field and be used in passenger cars!

Just like the competition between solid-state hard drives and mechanical hard drives mentioned by the editor of the science and technology landscape, everyone can see at a glance that solid-state hard drives have great technical advantages, but before they mature, mechanical hard drives still have huge room for development. This is the same as the competition between traditional classical computers and quantum computers. The prospects of quantum computers are immeasurable, but the development space of traditional classical computers is far from over.

Through these two points, let's take a look at the current lithium iron phosphate battery and ternary battery in the passenger car field. Who can laugh last is far from the time to make a conclusion. Sometimes, the development of science and technology is like this. Before the real leap, it has not achieved real transcendence. If you give up the development opportunity easily, it is actually equivalent to giving up the market. Without the market, how can you survive!
