Is the lithium ternary battery really not safe which is rejected by the Ministry of Industry ?

The Ministry of Industry and Information Technology recently made it clear that due to the safety of power batteries, the suspension of three lithium battery passenger cars included in the new energy vehicle promotion application recommended vehicle catalogue. The decision has sparked heated debate in new energy vehicles and the battery industry. Some people think that the three-way lithium battery has many advantages in terms of performance and should not be knocked down. It is more said that this is an erroneous act of intervening in market mechanisms and technological progress by administrative means.

In my opinion, or quotient, or learning, from the point of view of the proposer himself, these views have strong reasons. However, if they have the opportunity to stand in front of a new energy car burned by battery spontaneous combustion, all the reasons and excuses will appear pale. Safety, not profits or results, is arguably the number one priority for the development of electric vehicles.

As a national government department, making such a provocative decision, I believe that the Ministry of Industry and Information Technology is by no means, nor dare it for any economic purpose. The main reason why the three-element lithium battery is rejected is that the battery products under this technical route, the overall safety or product consistency, can not temporarily reach the level of mass use. In particular, it is used for passenger vehicles such as public transport. Once these vehicles have problems such as spontaneous combustion, they will inevitably cause huge losses of people's lives and property.

Of course, we must also see that this ban is "temporary". "Temporary" means that there is no complete negation, and it gives an improved and perfect time space. Compared with batteries such as lithium iron phosphate, ternary materials have the advantages of high energy density and are valued and actively developed in countries such as Japan and South Korea. With regard to the development trend in the technology field, our government has no reason to oppose and hinder the domestic battery industry from following the market perspective. On the contrary, through the publication of technical standards and other methods, in recent years, it has also greatly promoted the rise and development of the three-way technology route.

In fact, it is simply believed that the three-element lithium battery is not safe and is innocent. The lithium ternary material is easy to pyrolysis, but it does not represent the safety of the lithium ternary battery; lithium iron phosphate material is not easily pyrolysis, but it does not mean that lithium iron phosphate batteries are safe. Regardless of the technology route, it is affected by the "overactive" nature of lithium. Therefore, the safety of the battery is a matter of the entire system, not the material. Its solution is not simply to replace positive materials.

But then again: lives are bigger than days. Safety will always be the first, if not the only, criterion for electric vehicles to choose batteries until the lithium ion battery is technically proven to be a "clean and honest person". This is in the current market demand is huge, the current situation of the various ghosts and ghosts mixed, but also need to repeatedly emphasize and strictly regulate.

After all, in markets without regulation, capital would do anything for its own good.
