Two Thousand One Hundred and Sixty-Eight Wang Fried

The most basic standard models have a cruising range of 800 kilometers.

Of course, this 800 kilometers is an undiscounted 800 kilometers, no matter if you turn on the air conditioner in summer or the heater in winter.

Even if they hit the highway at a speed of 120 kilometers per hour, their cruising range must be guaranteed to be 800 kilometers.

If you don't consider turning on the air conditioner and heater, and run according to the most energy-saving power for 100 kilometers.

The mileage of this car can actually do a thousand kilometers!

The reason why they are so awesome is entirely because of their super electronic control system and that heat pump system.

This is also the main reason why they plan to set the price of the car to more than 300,000 yuan.

Because of these, the cost of the car is not low.

Selling it too cheaply will have a serious impact on the mid-to-low-end market and affect peers.

In addition, it does not meet the hearts of some consumers who install B.

The second mid-to-high-end model is a model with a cruising range of 1,000 kilometers.

Of course, the 'standard' battery life of this model is 1,000 kilometers, which is also the battery life when the air conditioner or heater is turned on, or 120 kilometers per hour.

If none of the above is true, then this car can actually drive 1,200 kilometers.

And the reason why it can be so awesome is because this car is a model with a quaternary lithium battery.

Because a certain amount of aluminum is added to the battery...

In fact, many companies have already had this idea.

The reason for this is very simple, to reduce costs.

Because the cost of ternary lithium batteries is too high, the nickel and cobalt inside are very expensive rare metals.

Especially cobalt, the price is ridiculously expensive, it costs 260,000 yuan per ton, and it is still rising.

If the demand for ternary lithium batteries is large in the future, then the price of this rare metal will definitely continue to rise.

Therefore, many companies are looking for new batteries to reduce their dependence on cobalt.

There are many companies who have come up with a solution, which is to add some other metals to the ternary lithium battery to reduce the cost.

And the election came and went, and many companies chose aluminum.

Aluminum was chosen because of its low cost and relatively reactive chemical properties.

The most important thing is that the use of this raw material will greatly reduce the cost of ternary lithium batteries.

To know the price of cobalt, it is now 260,000 yuan a ton, and the current situation is still rising.

But the price of aluminum is only 16,000 yuan per ton, and the current price is relatively stable.

The most important thing is that adding aluminum to the ternary lithium battery will greatly reduce the amount of cobalt.

According to the technology of Xinghuo Technology, the cobalt content in the quaternary lithium battery they made is 70% lower than that of the ternary lithium battery.

In addition, the advantages of this quaternary lithium battery are higher energy density and better safety.

Because it is nickel that determines the energy density of the battery, but if the amount of nickel is too high.

Then the opportunity to speed up the growth rate of lithium dendrites, so this battery can just add aluminum to the graphite negative electrode of the silicon carbon layer after adding aluminum.

In this way, the strength of the lithium battery can be strengthened, and even if the nickel will cause lithium dendrites, it will not cause a short circuit by piercing the separator in the middle.

This is the benefit of quaternary lithium batteries.

But the problem now is that although many companies also know that adding aluminum can make quaternary lithium batteries.

In principle, the material cost of this kind of battery is lower than that of the ternary lithium battery.

But in fact, the manufacturing process is very complicated, the material cost is reduced, but the manufacturing process cost is greatly increased. Valley

And because the process is complicated and very power-consuming, this leads to high costs.

Many companies can't afford to use them, and even if they are produced, there will be problems of one kind or another because the craftsmanship is not up to standard.

But these problems that plague other companies are not a problem for Spark Technology.

what manufacturing process,

For them it was all pediatrics.

With those cloning experts, the manufacturing process of this quaternary lithium battery was easily conquered.

And a total of three processes have been developed, which can not only greatly reduce the complexity, but also greatly reduce the cost.

Of course they never say it publicly.

And this quaternary lithium battery, in fact, they still retain considerable room for improvement and upgrading.

The normal battery life of 1200 kilometers is far from the limit of this battery, but 1500 kilometers.

Of course, this is also to leave room for them to improve in the future.

As for the most advanced Extreme Edition model, the price is definitely going towards a hundred W.

The target is Mercedes-Benz, or Lexus luxury cars.

These two cars are very marketable in China, because one represents the B-frame, and the other represents the economy in high-end cars.

In this field, let alone our domestically produced cars, even foreign luxury brand cars are difficult to compete with.

If you want to enter the high-end field, you must pull down this brand one by one.

And their Extreme Edition model is rushing to this goal.

Since we want to pull these two brands down, we must have housekeeping skills.

So what are their housekeeping skills, this is another secret weapon that Spark Technology is developing.

That is a semi-solid lithium battery.

In fact, with the strength of Xinghuo Technology, they can even directly create solid-state batteries. ,

Even more exaggerated, they can come up with small controllable reactors.

But the problem is that if those big killers are taken out, it might cause a world war.

So under Xiao Feng's suggestion, they chose to hide.

The meal must be eaten one bite at a time, and the road must be taken step by step, so don’t be in a hurry.

So it is enough to take out a semi-solid lithium battery first.

The so-called semi-solid lithium battery is actually a complete set of ceramic tubes and ceramic separators installed inside the lithium battery.

In this way, the electrolyte can be more effectively protected, so that the electrolyte will not run around, and it is safer and at the same time.

It can also keep the electrolyte in a constant temperature state for a long time in the ceramic tube, which further ensures the efficiency of their charge and discharge.

You must know that for ordinary trams, although the cruising range is long, the charging time has always been unsolved.

In order to ensure the safety of the battery, do not dare to charge too fast.

Because charging is too fast, it is easy to cause lithium dendrites.

But after using this semi-solid battery, there is no need to be afraid of such problems.

With this kind of battery, you can really charge for ten minutes and run all day...

And this is the king fried in the secret care of Chenhua Auto!

At this year's auto show, they only unveiled a hybrid car, and they did not launch an electric car.

Just to wait for next year, when the technology matures, they will throw a series of king bombs...
