Lithium batteries will replace lead acid?

What caused battery manufacturers to be extremely uneasy in April was the release of the new national standard for batteries at the end of 2017:

"Battery for electric auxiliary vehicles, Part 1 Technical Conditions",

Electric power battery part 2, product variety specification.

These two documents are not comments on the draft, but have been issued, and will be strictly implemented on July 1, 2018!

This is a landmark battery new national standard! It will have an important impact on the battery-electric car heart supporting industry: the era of technology upgrade, battery requirements for lightweight design, half of the battery manufacturers may face a new round of elimination!

The new national standard requires the battery to change in the direction of lightweight and high-energy

Why is the new national standard so influential?

(1) The new national standard for lead-acid batteries introduced the energy density standard for the first time and put forward the requirement that the energy density should be high

What is the energy density ratio?

The standard definition of the new national standard is as follows:

Definition:

Calculation formula:

Excerpted from Batteries for Electric Auxiliary Vehicles, Part 1 Technical Conditions

Energy density = battery volume/battery weight

The new national standard requires that the energy density must be up to the standard(high to the specified index of the corresponding model product) before it is considered a national approved product. Therefore, under the condition that the battery has the same capacity, the lighter the weight of the battery itself, the higher the energy density

This raises the next question. The more weight you lose, how do you ensure that the capacity remains the same or even more than it was before?

Answer: new technology, new material!

Of particular note here are:

Small factories face direct elimination because they do not have funds and R&D capabilities to follow up;

Due to the scale of the large plant, the ship is not good at turning around, and it is difficult to quickly switch in the short term. If the later period can not keep up with the rhythm, it is sooner or later.

Only those enterprises that have advanced their layout and achieved rapid technological upgrading can truly enjoy the dividends brought by this wave of policies.

The true purpose of the battery's new national standard!

In essence, the new national standard is to establish new standards and requirements for traditional lead-acid battery technology, thereby promoting enterprise technology changes, improving the technical content of products, and improving the core competitiveness of China's lead-acid battery field. After all, for many years, in the traditional manufacturing field of lead-acid batteries, low thresholds and homogenization have caused serious overcapacity in the industry, which is unsustainable for the environment and the development of the market. Therefore, the elimination of backward production capacity is inevitable.

The development of electric car batteries is getting more and more difficult

Now the new national standard requires lightweight design to increase energy density

Another batch will be eliminated.

Lithium battery development is overwhelming! Hey!
