After New Year's Day, the twelfth lunar month of winter comes, the weather becomes colder and the people's hearts become more and more impetuous.

After a busy year, people's minds have long been away from work, and now they are only thinking about going home to reunite with their loved ones.

The start of the annual Spring Festival Transport has also kicked off the largest population migration cycle on the planet. This year's Spring Festival transportation ticket supply is still tight. In order to allow employees to work with peace of mind, Wu Hao and others specially opened the company's private network for everyone to grab tickets.

But even so, there are still many people who have not grabbed tickets to go back during the Chinese New Year. Some people immediately decided not to go back this year, while others were looking for other options.

For example, there is an employee in the company's marketing department whose family is from the Northeast. In order to buy a ticket home, he found a new way. He first bought a ticket to Japan, and then transferred from there to the Northeast.

Although the ticket price is a bit expensive, I can finally go back. This is the tradition of our people, and it is also the blood-and-blood relationship that is deep in our bones. No matter how much suffering we go through, we just want to reunite our families.

Taking advantage of nothing happening before the year, the company's departmental integration and adjustment work has just begun. Although it has experienced some turbulence, everything is still proceeding in an orderly manner.

However, Zhang Jun, Dong Yiming and others were responsible for all these, while Wu Hao himself got into his personal laboratory.

"Hey, I heard that you went to that charity reception a few days ago and met a girl. I heard that you gave her a pendant worth hundreds of thousands." The big screen showed an image of Zhang Jun sitting in the office. , this guy likes to dress up like a dog now.

A large custom-made suit made him look more like a general manager, but his weight of 230 made him have to start dieting to lose weight.

Wu Hao glanced at the guy on the big screen, and then continued to work: "Why are you gossiping like this? Hurry up and get busy with your work."

"What gossip? I'm only concerned about your life-long affairs, okay? I heard that girl is not bad, so you better hold on tight." Zhang Jun showed a lewd smile at him.

"Go away, you should mind your own business."

Wu Hao snarled angrily, and then said to him: "How is the situation at your place today?"

Seeing Wu Hao talking about business, Zhang Jun immediately put away his smile and said seriously: "It's not going well. There are many problems with the merger of the marketing department and the operations department, and there are also some internal disputes. It may take some time for the two groups to integrate.

In addition, the production department also has a lot of troubles, especially in terms of setting up the department framework, which lacks many talents. In this regard, Dong Yiming and I are working with Lin Jianliang to figure out a way to see if we can first recruit talents for a few key positions from elsewhere, and other personnel will be slowly added after the new year. "

Wu Hao nodded and said: "That's all we have for now, but you have to pay attention to it. You can delegate power in terms of management, but you must keep a tight grip on personnel appointments and not let others interfere. Is that clear?"

"Don't worry, I'm not a fool."

Zhang Jun smiled, and then asked him: "Shen Xiaoxian asked me to inform you that the annual meeting will start at seven o'clock tomorrow evening. The company is on holiday tomorrow afternoon, don't forget it."

"I can't forget it." Wu Hao replied with a smile.

"What have you been tinkering with in the laboratory these days? Have you achieved anything?" Zhang Jun asked curiously, looking at the various equipment placed behind him through the camera.

"There is some progress, but it is still being tested."

"Okay, if you don't want to say forget it, I'll be busy first. You should take some rest and don't forget everything as soon as you get busy." Zhang Jun gave him a few instructions and quickly logged off.

The picture on the big screen flashed, and then Coco's avatar appeared: "The call is over."

Cocoa, how many times have the samples No. 1 to No. 5 been rapidly charged and discharged?

"The rapid charge-discharge cycle experiment of samples No. 1 to 5 has been tested 273 times at 80% full charge state and 1,326 times at half charge state. .”

"How is the sample shape?" Wu Hao looked at the data on the big screen and asked.

"The capacity of sample No. 1 decays to 10% after cycling, and the actual power in the sample is currently 72%. The capacity of sample No. 2 decays from 10% to 14% after cycling. The actual power is 68.8%. The capacity of sample No. 3 decays to 7% after cycling. The sample..."

"So, the sample No. 3 is currently in the best shape?" Wu Hao asked

"Yes, judging from the current testing, sample No. 3 has the least capacity decay after cycling and the most stable shape."

"Seven percent, totaling it to..."

"Five and a half percent, sir!"

"Coco!" Wu Hao looked at the image of Coco on the screen and said seriously.

Coco said with a smile on the screen. "Yes, sir."

"Don't rush to answer in front of me in the future."

On the screen, Coco still smiled and clicked lightly. "Okay, sir!"

"What's the point of following a program?" Wu Hao patted his head, then sat down and took out the sample marked No. 3.

This is a battery that Wu Hao is testing. Simply put, it is still a lithium-ion battery, but he has optimized the battery technology.

In fact, the structure of the battery itself and the formula of the electrolyte have been optimized, which simply means increasing the energy storage density within a single volume.

Take two 30-gram lithium-ion batteries as an example. Among the major lithium-ion batteries currently on the market, the 30-gram battery can hold a thousand milliamp hours of electricity. After optimization by Wu Hao, the capacity of a 30-gram lithium-ion battery will reach about 1,300 mAh, and its energy storage density will be increased to about 30%.

Of course, this is just experimental data in the laboratory. Wu Hao only achieved a relatively ideal result by using the knowledge stored in his mind and combining it with the materials currently available.

Specific results require further experimental data to obtain, and developing a battery not only depends on its capacity, but also a series of other factors.

For example, whether this battery is safe or not? News about battery explosions are common. In a modern society that attaches great importance to safety performance, if the safety of a product is not guaranteed, it will lose its competitiveness.

Take a certain mobile phone brand as an example, because a mobile phone exploded several times within a year. This mobile phone brand has been greatly affected on a global scale, and even caused a serious brand trust crisis. In the end, the mobile phone manufacturer had to apologize and recall all overseas mobile phones of this brand.

In addition, there are also whether the materials used inside the battery are safe and reliable, whether they are toxic, and how much pollution they can cause.

The last and most important thing is the manufacturing cost of this battery. If the cost is too high, it will lose its market competitiveness.
