After New Year's Day, it came to the middle of winter and the twelfth lunar month. The weather became colder and people's hearts became more impetuous.

People who have been busy for a year have long been out of work, and now they are full of thoughts about going home to reunite with their relatives.

The opening of the annual Spring Festival travel work has opened up the largest population migration cycle on the planet. This year's Spring Festival transport ticket source is still tight, in order to allow employees to work with peace of mind, Wu Hao and the others specially opened up the company's dedicated network for everyone to grab tickets.

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

For example, there is an employee in the marketing department of the company. His family is in the Northeast. In order to buy a ticket to go home, he finds another way.

Although the fare is a little expensive, but I can finally go back. This is the tradition of our countrymen, and it is also a family relationship that can be found in the bones. No matter how much suffering you experience, it is for family reunion.

Taking advantage of the fact that there was nothing to do a few years ago, the company's departmental integration and adjustment work has just begun. Although there have been some turmoil, the overall process is still proceeding in an orderly manner.

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

"Hey, how did I hear that you went to that charity reception a few days ago and met a girl, and I heard that you gave her a pendant worth hundreds of thousands." The big screen showed the 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 two hundred and thirty forced him to start a diet to lose weight.

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

"What gossip, I'm concerned about your lifelong affairs, okay? I heard that girl is not bad, you should hold on tight." Zhang Jun showed him a wretched smile.

"Go away, you'd better mind your own business."

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

Seeing Wu Hao talking about the business, Zhang Jun put away his smile and said seriously: "It's not going well, the merger of the marketing department and the operation department has many problems, and there are also some internal disputes.

It may take some time for the two groups to merge.

In addition, there are also many troubles in the production department, especially in the construction of the department framework, which lacks a lot of talents. In this regard, Dong Yiming and I are working with Lin Jianliang to find a way to see if we can poach a few key talents from other places first, and gradually add other personnel after the next year. "

Wu Hao nodded and said: "This is the only way to do it now, but you should also pay attention to it. Management can be delegated, but personnel appointments must be firmly in hand. Can't others interfere with it?"

"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 night. The company is on holiday tomorrow afternoon, don't forget."

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

"What have you been fiddling with in the laboratory these days, have you got any results?" Zhang Jun looked curiously at the various equipment placed behind him through the camera.

"There is some progress, but it is still in the experimental stage."

"Well, if you don't want to say it, forget it, I'm busy first. You should pay attention to rest, and don't forget everything when you get busy." Zhang Jun gave him a few instructions, and quickly logged off.

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

Cocoa, how many times have you done the rapid charge and discharge experiments for samples 1 to 5.

"The rapid charge and discharge cycle experiments of samples 1 to 5 have been tested 273 times at 80% full charge, and 1326 times at half charge. .”

"How about the sample shape?" Wu Hao asked after looking at the data on the big screen.

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

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

"Yes, judging from the current test situation, the capacity fading of sample No. 3 after cycling is the least, and the shape is the most stable."

"Seven percent, calculated to be..."

"Five and six per cent, sir!"

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

Coco smiled on the screen. "Yes, sir."

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

On the screen, Ke Ke still smiled and tapped lightly. "Yes, sir!"

"What do I call 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, it is to optimize the structure of the battery itself and the formula of the electrolyte. Simply put, it increases the energy storage density in a single volume.

Take two lithium-ion batteries with the same weight of 30 grams as an example. The 30-gram lithium-ion batteries currently on the market can hold 1,000 mAh of electricity. After being optimized by Wu Hao, the same 30-gram lithium-ion battery will have a capacity of about 1,300 mAh, and its energy storage density will increase to about 30%.

Of course, this is just experimental data in the laboratory. Wu Hao is only using the knowledge stored in his mind and combining the materials that can be accessed and used at present to achieve a relatively ideal result.

Specific results still need further experimental data to obtain, and the development of a battery not only depends on its capacity, but also considers a series of other factors.

For example, whether this battery is safe or not, the news of battery explosion is endless. In the modern society that attaches great importance to safety performance, a product will lose its competitiveness if its safety is not guaranteed.

Take a mobile phone brand as an example, because a mobile phone has exploded several times within a year. As a result, 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, whether the materials used in the battery are safe and reliable, whether they are toxic, and how much pollution they can cause.

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