Chapter 347 Overtaking on a curve, no problem at all(1/2)

Nanshan Group takes the route of relying on technology to win orders.

This is a slogan that Cao Yang has been promoting within the company.

Now that we have started to produce cars, it is natural that Xingchen Automobile’s products should have technical content.

Otherwise, how can you take the high-end route?

In terms of brand heritage, no matter how you market it, there is no way to compare it with established car companies such as Porsche, Mercedes-Benz, and Rolls-Royce.

But technically it is possible to break through.

There is no problem in building high-performance cars that surpass those in the industry by relying on technology that surpasses those in the industry.

Based on this idea, many of the technologies used by Cao Yang on Xingchen 2 and Xingchen 3 were more than ten years ahead of this era.

Although it cannot be said to be a black technology, it is definitely amazing enough.

When the time comes, there will be absolutely no problem in using it to run races or continue to do laps in Niubei.

If the w16 engine is developed in the future, then from w12 to w16, the performance of the high-end version will definitely be even better.

So soon, in addition to handling some of the company's main matters, he began to invest a lot of time in technology research and development.

"Mr. Cao, currently the members of our battery team are good at different things."

"Some people were previously studying batteries used in pure electric vehicles. If they were allowed to switch to the research and development of FHEV batteries, it would not be impossible, but it would be a waste of talent, and the other party might not be very happy."

"Some people used to study lithium nickel oxide batteries, and now it will take some time to switch to lithium nickel cobalt manganate batteries."

"Electric vehicles are the future direction, but whether they are FHEV, PHEV, or BEV, they should have their own market in the future."

"We may not need to devote all our R&D talents to fhev batteries alone."

Lin Cheng is a professor recruited from a university by Nanshan Group and now serves as the deputy general manager of Nanshan Battery.

The position of general manager is temporarily vacant.

As a professor from a university, his professional level is not a problem.

However, since it was involved in several directions before, it is natural that we now hope to make efforts in several fields at the same time.

Otherwise, if the bet is wrong, wouldn't all the efforts be meaningless?

"Professor Lin, your analysis also makes sense."

"We do not need to limit the research on FHEV batteries. PHEV and BEV can also be developed simultaneously."

"However, in the short term our focus will definitely be on FHEV batteries. After all, this is what will be used soon on Xingchen 3."

"As for the battery chemistry system, based on the company's previous research, I think we only need to study two types of lithium iron phosphate batteries and lithium nickel cobalt manganese oxide batteries at this stage."

"Although other lithium cobalt oxide batteries, lithium manganate batteries, lithium nickel oxide batteries, etc. all have their own advantages, the corresponding shortcomings are also very obvious."

"Like lithium cobalt oxide, Sony first applied it commercially, and it has excellent properties of high specific capacity and low self-discharge."

"But the cost is high, the thermal stability is poor, and the battery decays quickly when subjected to high rates and deep cycles, making it unsuitable for use in electric vehicles."

"Lithium manganate is cheap enough, but it is not inferior to other types in terms of energy density and power density."

If you want to convince a talent like Lin Cheng who came out of college to convince you, the best way is to show your professionalism in front of him.

If you make him feel powerful in the professional field, he will naturally become much easier to communicate with.

So Cao Yang was going to have a good chat with Lin Cheng about batteries.

"Mr. Cao, everything you said is correct."

"No matter which material the battery is made of, it actually has its own advantages and disadvantages."

"New lithium-ion battery electrode materials such as lithium iron phosphate are characterized by large discharge capacity, low price, non-toxicity and no environmental pollution."

"Currently, countries around the world are racing to achieve industrial production, but its tap density is low, which affects the capacitance and may not be suitable for the needs of electric vehicles."

"Lithium nickel cobalt manganate batteries can effectively increase the cell voltage by increasing the nickel content, thereby obtaining higher energy density."

"And because it contains less cobalt, the cost is only a quarter of that of lithium cobalt oxide and is more environmentally friendly."

"This material is indeed a hot research topic in the battery field, but it does not have its own problems."

"A basic fact is that as the nickel content increases, the specific capacity of the ternary cathode material gradually increases, and the energy density of the battery core will also increase accordingly."

"However, the thermal stability of high-nickel materials in the state of charge is poor, which leads to a decrease in battery safety. Battery manufacturers and end product users are concerned about the safety of this battery. They need to consider battery cell design and power supply system.

Design, power supply and other aspects to ensure reliable and safe design of the system."

"There are various other specific technical issues, but none of them have been completely resolved."

When talking about professional matters, Lin Cheng was still very enthusiastic.

This is his area of ​​expertise.

He also wanted to take this opportunity to let his boss see his level.

"You are right, every type of battery has its own problems."

"At this time, the vision of each enterprise will be tested."

"If the future development trend is lithium iron phosphate batteries, but we focus on lithium cobalt oxide batteries, then there will definitely be no future."

"On the other hand, the industry is still not sure which battery technology is easier to achieve breakthroughs and become the future development direction."

"If we can make a successful choice, we will be able to overtake others and become the leading battery company in the industry."

"Frankly speaking, our research history in battery technology is definitely not comparable to companies such as Sony, Panasonic and Toshiba, nor can it compare to Korea's LG Chem and SK Innovation."

"Even domestic BYD and some other companies have a longer history in battery research than we do."

"But as long as we choose the right direction, it is not impossible to overtake in corners."

"In the future, lithium nickel cobalt manganate batteries will be our main high-performance batteries, and lithium iron phosphate batteries will be our main low-cost batteries."

"The combination of these two paths can allow us to quickly become the leader in the industry."

"Of course, what I'm talking about is within ten years. If we look at it in the long run, research on semi-solid batteries and solid-state batteries will definitely be involved in the future."

"It's just that our Nanshan Battery hasn't even learned to walk yet, so we can talk about running later."

Cao Yang is very determined to take the route of lithium iron phosphate and lithium nickel cobalt manganate batteries.

This is a path to success that has been proven by history.

Among the four main materials of the battery, positive electrode material, negative electrode material, electrolyte and separator, the positive electrode material not only accounts for more than 40% of the cost, but also directly determines the energy density of the battery core.

Because of this, most power batteries are named after the cathode material.

Lithium iron phosphate and lithium nickel cobalt manganate batteries are naturally no exception.

In later generations, both Catl and BYD will focus on these two products.

Of course, everyone's focus is different.

BYD is better at lithium iron phosphate batteries, while Catl is better at nickel cobalt manganese batteries.

"Mr. Cao, the two research directions you mentioned are indeed one of the popular research areas in the industry."

"There are many choices for battery cathode materials. We have to study them all, which is obviously unrealistic."

“It’s not impossible to lock in a target and delve deeply into this field.”

After all, it was the boss's decision, and Lin Cheng was not so stubborn in his objection.

The most important thing is that what Cao Yang said is not unreasonable.

It's just that Lin Cheng has no way to directly determine the research direction.

Now that Cao Yang's attitude was so obvious, he naturally no longer struggled.

Of course, he is mainly involved in this field, and even lithium nickel cobalt manganese oxide batteries are an area in which he is relatively good.

You can also use your advantages in the future.

"Good steel must be used on the blade. Although there are two research and development directions now, our Xingchen 3 is a sports car, and it must use lithium nickel cobalt manganate batteries with better performance."

"In this case, Nanshan Battery's fhev battery must use lithium nickel cobalt manganate as the cathode material."

"Then the next work is to discuss how to implement this technology into specific parts."

Cao Yang is here to "reinforce the development of new projects". Now that the battery used on Xingchen 3 has encountered a development bottleneck, he naturally has to "reinforce the development of new projects".

"Mr. Cao, we have also done some industry research in this regard, reviewed many related papers, and already have some ideas."

"Preliminarily, prismatic batteries should be a more suitable type for use in hybrid batteries."

"Considering that hybrid batteries do not require much power, basically two kilowatt-hours of electricity are enough."

"But it has high power requirements, so we plan to use lithium nickel cobalt manganate batteries with a relatively low nickel content, which can better meet the technical needs of hybrid batteries."

"However, the corresponding cost will be higher than that of high-nickel batteries."

Lin Cheng began to discuss it seriously with Cao Yang based on his previous research.

"The cost of power batteries is definitely higher than that of energy batteries."

"Especially for hybrid batteries, because they need to be charged and discharged quickly in a short period of time or with high power, the requirements for positive and negative electrode materials and separators are very high."
