Rebirth 2004: I can make money by writing

In the afternoon,

Hao Qiang drove to the lithium battery experimental factory.

The company is currently mainly developing 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 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 NCM (nickel cobalt manganese).

Hao Qiang’s company has research on both types of batteries.

NCM (nickel cobalt manganese) battery is one of the main products of Ningde Times in the early days, and it is also the main battery type for domestic pure electric vehicles.

With the continuous development of technology, Ningde Times has gradually launched high-nickel system NCM batteries, such as NCM811 (nickel cobalt manganese ratio is 8:1:1), etc. This type of battery has higher energy density and lower cost, and is suitable for long-distance vehicles 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 electric vehicles and hybrid vehicles.

The NCM formula in the third-level technology that Hao Qiang got is actually the technology of Ningde Times in the early and middle stages, not NCM811.

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

It’s just that he doesn’t know it for the time being.

Even if he knows, the difficulty of research and development is very high.

The current NCM formula developed has a ratio of 5:2:3 of nickel, cobalt and manganese. Hao Qiang calls it NCM523, which is also the mainstream ternary lithium NCM ratio in the next ten years.

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

The 4-valent nickel ions in high nickel have high catalytic activity, fast oxidation and decomposition, and are easy to destroy the electrolyte structure.

So, it is not that you can develop it 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 nickel and electrolytes.

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

Throughout the year, the average spot price of LME nickel on the London Metal Exchange is US$14,738 per ton;

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

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

A ternary lithium battery pack with a capacity of 50 degrees has a cell weight of about 210 kilograms. According to the NCM523 formula, the total weight of nickel and cobalt materials is about 70 kilograms, and the material cost alone is 15,000 yuan.

This is also the reason why the price of an electric vehicle battery pack is nearly 100,000 yuan.

The production cost of other battery factories is not low.

Hao Qiang put on work clothes and worked with scientific researchers to develop NCM523.

Sometimes, he would operate it himself, but most of the time he was instructing the work.

Although he knew the electrolyte formula, the experiment was carried out step by step. He kept experimenting to get data and analyze the direction, which was not achieved overnight.

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

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

So, Hao Qiang has the right direction, but at the beginning, he will not interfere with the researchers, but let them try and make mistakes and analyze continuously.

After it is almost done, he will guide the researchers in the right direction.

Hao Qiang experimented for an afternoon and left when it was almost time to get off work, leaving behind employees who were constantly shocked.

“The boss is really amazing. It seems that he knows everything. Didn’t he study electronic science and technology?” An engineer was a little puzzled.

“The chairman knows a lot, otherwise why is he called the chairman?” An employee said with a smile, “I’m not flattering him. He’s just a sophomore, but he can read CAD and 3D diagrams, understand 5S, welding technology, machining technology and cutting technology, and he’s even better at playing with lithium batteries.”

“Well, just treat the boss as a genius. Everything is possible with him.”

“The most rare thing is that the boss has no airs and personally experiments with us without fear of getting dirty. If he were an ordinary young rich man, he would probably be picking up girls in KTV.”

“The boss’s grades are the best in his major. He can get full marks in the CET-4. He’s a pervert. We should treat him as a genius among the geniuses in Qingbei.”

“Yes, don’t guess his knowledge based on his major. Maybe he has learned a lot of things in his spare time.Professional knowledge.

Engineers are often surprised by Hao Qiang’s profound knowledge. Don’t think that he doesn’t know because he is young. Maybe he is more professional than you.

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

Not to mention anything else, there are so many people in the company, and he seems to be able to call out everyone’s name.

With Hao Qiang’s participation, various scientific research work progressed smoothly.

On September 27,

F1 electric motorcycles have gone through countless road tests and vehicle optimizations for several times. After three inspections by Hao Qiang, it was truly finalized.

After finalization, we began to design and make tooling and fixtures, and tried to mass produce it.

On September 28,

Hao Qiang attended a discussion meeting on tooling and fixture design. He emphasized at the meeting: “All designed tooling and fixtures must undergo process review. Without review, they cannot be directly produced.

Our products are mass-produced. If the production efficiency of each component is a few seconds faster, or the rework rate is reduced a little, the production cost will be much lower. ”

He worked in a machinery factory and found that many fixtures were not easy 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 fixtures.

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

First, all designers must track the fixtures they design, and after they are made, they must clamp them themselves and check whether they are easy to use;

Second, lightweight;

Third, design lifting points or pallet forklift lifting points to facilitate workers to install and carry. ”

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

In fact, the boss’s demanding requirements are right.

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

In half a month, F1 will be exhibited at the Canton Fair.

Lin Yan is still eager to get a big order, not just for the exhibition.

Two days later, the National Day arrived.

The school is on holiday, the Future Technology Group is also on holiday, and the Renjian Fireworks employees go to work as usual.

The company issued a 200 yuan supermarket shopping voucher to each employee.

Two weeks ago was the Mid-Autumn Festival, and the company also issued 200 yuan supermarket shopping vouchers to employees, allowing employees to buy moon cakes by themselves.

If the moon cakes are not good, they will be complained by employees, so Hao Qiang simply decided to issue shopping vouchers.

If cash is issued, employees are reluctant to spend, and issuing shopping vouchers is to force employees to spend.

The company’s expenditure is the same, but the happiness of employees is different.
