Rebirth 2004: I can make money by writing.

In the afternoon,

Hao Qiang drove to the lithium battery experimental factory.

The company is currently focusing on the research and development of ternary lithium batteries for electric vehicles.

The so-called ternary refers to the three main metal elements of the positive electrode material.

The positive electrode is generally a ternary positive electrode material composed of three metal elements: nickel (Ni), cobalt (Co) and manganese (Mn) or aluminum (Al).

Among them, nickel mainly improves the energy density of the battery, cobalt helps to improve the structural stability of the battery, and manganese or aluminum mainly improves the safety and life of the battery.

Therefore, ternary lithium mainly refers to NCA (nickel cobalt aluminum) and NMC (nickel manganese cobalt).

Hao Qiang's company is researching both types of batteries.

NMC (nickel manganese cobalt) batteries were one of CATL's main early products and are also the main battery type for domestic pure electric vehicles.

With the continuous development of technology, CATL has gradually launched high-nickel system NMC batteries, such as NCM811 (nickel, cobalt and manganese ratio is 8:1:1), etc. This type of battery has higher energy density and lower cost, and is suitable for scenarios such as long-distance use and high-end models.

NCA batteries have the characteristics of high energy density, long cycle life and excellent thermal stability, and are widely used in fields such as electric vehicles and hybrid vehicles.

The NMC formula in the third-level technology that Hao Qiang obtained is actually the early and mid-stage technology of Ningde Times, not NCM811.

NCM811 is only found in the ternary lithium formula of the four-level technology.

But he just doesn't know it yet.

Even if we know it, the difficulty of research and development is still very great.

The NMC formula currently under development has a nickel-cobalt-manganese ratio of 5:2:3, which Hao Qiang calls NCM523. It will also be the mainstream NCM ratio for ternary lithium in the next ten years.

As the proportion of nickel in positive electrode materials increases, the research and development of electrolytes also faces challenges.

The tetravalent nickel ions in high nickel have high catalytic activity, fast oxidation and decomposition rate, and can easily destroy the electrolyte structure.

So, it is not possible to develop a product just by having a formula.

If there are slight differences in the process, it may not be successful.

At present, Hao Qiang is mainly responsible for the research and development of electrolytes and is working hard to solve the problems of positive electrode nickel and electrolytes.

At the same time, he is also learning about the current international market prices of nickel, cobalt and manganese.

Throughout the year, the average spot price of nickel on the London Metal Exchange (LME) was US$/ton;

Cobalt metal is much more expensive, about 3.5 times that of nickel.

The price of electrolytic manganese is much cheaper, just like 304 stainless steel, only about 10,000 yuan per ton.

A 50-kWh ternary lithium battery pack has a cell weight of about 210 kilograms. According to the NCM523 formula, the total weight of nickel-cobalt materials is about 70 kilograms, and the material cost alone is 1.5 yuan.

This is also the reason why an electric car battery pack can cost nearly 100,000 yuan.

The production cost of other battery factories is not low.

Hao Qiang changed into work clothes and worked with the researchers to develop NCM523.

Sometimes, he would do the work himself, but mostly he would provide guidance.

Although he knew the electrolyte formula, the experiment was carried out step by step. He had to experiment continuously to obtain data and analyze the trends. It was not something that could be done overnight.

In addition, Hao Qiang would not give the formula directly to employees, but let them make mistakes through trial and error.

Trial and error is also a form of growth. If everything depends on the data he provides, it will not be good for your company.

So, Hao Qiang had the right direction, but at the beginning, he would not interfere with the scientific researchers, but let them continue trial and error and analysis.

Only when it is almost done will he guide the researchers in the right direction.

Hao Qiang experimented for an entire afternoon and left just as get off work was about to end, leaving his employees in constant shock.

"The boss is amazing. He seems to know everything. Didn't he major in electronic science and technology?" An engineer was a little confused.

"The chairman knows so much, otherwise why would he be called the chairman?" an employee said with a smile. "I'm not trying to flatter him. He's just a sophomore, but he can read CAD and 3D drawings, knows 5S, and knows welding, machining, and cutting processes. He's even better at lithium batteries."

"Well, just think of the boss as a genius. Everything is possible for him."

"The most rare thing is that the boss is humble and personally experiments with us, not afraid of getting dirty. If it were any other wealthy young man, he would probably be picking up girls at KTV."

"The boss is the top student in his major and even got a perfect score on the Level 4 exam. He's a complete freak. We should just treat him as the genius among the geniuses in Qingbei Village."

"Yes, don't speculate on his knowledge based on his major. He might have learned a lot of industry knowledge in his spare time."

Engineers are often amazed by Hao Qiang's profound knowledge. Don't think that he doesn't understand because he is young. He may be more professional than you.

Many engineers were a little arrogant before joining the company, but they were soon impressed by Hao Qiang.

Apart from anything else, there are so many people in the company, it seems like he can call out everyone's name.

With Hao Qiang's participation, various scientific research tasks have progressed smoothly.

On April 27th,

The F1 electric motorcycle underwent countless road tests, several rounds of vehicle optimization, and three inspections by Hao Qiang before it was finally finalized.

After the design is finalized, we start designing and making tooling fixtures, and try to find a way to mass-produce it.

9 month 28 day,

Hao Qiang attended a discussion meeting on tooling and fixture design, where he emphasized, "All designed tooling and fixtures must undergo a process review. Without this review, they cannot be put into production directly.

Our products are mass-produced, and if the production efficiency of each component is increased by a few seconds, or the repair rate is reduced a little, the production cost will be much lower."

He had worked in a machinery factory and found that many tooling fixtures were difficult to use and had to be modified after they were made.

Many designers think that product design should be strict, but they can be more relaxed when designing tooling and fixtures.

He then emphasized: "I have three more requirements for fixtures:

First, all designers must track the fixtures they design, install them themselves after they are manufactured, and check whether they work well.

Second, lightweight;

Third, design the lifting points or pallet truck lifting points to facilitate workers’ installation and transportation.”

After the meeting, Lin Yan, vice president of the motorcycle company, personally supervised the design of tooling and fixtures and participated in the review of each set of tooling and fixtures.

In fact, the boss's harsh demands are correct.

Before the F1 is finalized, continuous test runs are carried out in order to optimize the model, make production easier, and thus reduce production costs.

In half a month, F1 will hold an exhibition at the Canton Fair.

Lin Yan is still eager to get big orders, not just exhibitions.

Two days later, National Day arrived.

The school is on holiday, Future Technology Group is also on holiday, but Renjian Fireworks employees are working as usual.

The company gives each employee a supermarket shopping voucher worth 200 yuan.

Two weeks ago was the Mid-Autumn Festival, and the company also distributed 200 yuan supermarket shopping coupons to employees so that they could buy mooncakes themselves.

If the mooncakes were not good enough, employees would complain about it, so Hao Qiang simply decided to give out shopping coupons.

If cash is given out, employees will be reluctant to spend it, but giving shopping vouchers will force them to spend it.

The company's expenditure is the same, but the employee happiness is different.
