After New Year's Day, it came in the middle of winter, the weather became colder and colder, and people's hearts became more and more impetuous.

After a busy year, people's minds have long been out of work, and now their minds are full of thoughts about going home to reunite with their loved ones.

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

But even so, there are still many people who have not grabbed the ticket to go back for the upcoming 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, his family is from the Northeast, in order to be able to buy a ticket to go home, he found another way, first buy a copy to fly to the country, and then transfer from there to the Northeast.

Although the ticket price is a little expensive, I can finally go back. This is the tradition of our people, and it is also the blood and family relationship in the bones. No matter how much suffering you go through, it is for the sake of family reunion.

Taking advantage of the fact that there was nothing to do before the year, the company's departmental integration and adjustment work was also the beginning. Although there have been some turbulences, the whole is still in an orderly manner.

However, Zhang Jun and Dong Yiming were all in charge of these things, and 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 also gave someone a pendant lot of hundreds of thousands." The big screen shows Jang Jun sitting in his office, and this guy now likes to dress up like a dog.

A wide custom-made suit made him more and more like a general manager, but his weight of two hundred and three made him have to start dieting to lose weight.

Wu Hao glanced at the guy on the big screen, and then continued to work busily: "What are you doing so much gossip, hurry up and busy your work." ”

"What kind of gossip, Lao Tzu is concerned about your life's affairs, okay? I heard that the girl is not bad, you kid hold on. Zhang Jun smiled lewdly at him.

"Fuck off, you'd better mind your own business."

Wu Hao scolded angrily, and then said to him: "How is the situation on your side today?" ”

Seeing Wu Hao talking about business, Zhang Jun immediately put away his smile and said seriously: "It's not going well, there have been many problems with the merger of the marketing department and the operation department, and there have been some internal disputes, and I'm afraid it will take some time for the two groups to integrate."

In addition, there are many troubles on the production department, especially in the construction of the departmental framework, and there is a lack of many talents. In this regard, Dong Yiming and I are working with Lin Jianliang to find a way to see if we can dig up a few key positions from other places to come back, and the rest of the personnel will be slowly replenished after the year. ”

Wu Hao nodded and said: "At present, it has to be like this, but you also have to pay attention to it, the management can be delegated, but the personnel appointment must be firmly grasped in hand, and other people must not be allowed to interfere." ”

"Don't worry, I'm not stupid."

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." Tomorrow afternoon the company has a holiday, don't forget. ”

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

"What have you been fiddling with in the lab for the past few days, and have you achieved any results?" Zhang Jun looked at the various devices behind him through the camera and said with some curiosity.

"There has been some progress, but it's still being tested."

"Well, I don't want to say forget it, I'm busy first. Take your own rest and don't forget everything when you get busy. Zhang Jun instructed him twice and quickly went offline.

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

Cocoa, how many times have samples from one to five been tested for rapid charging and discharging.

"Experiments on rapid charge-discharge cycles for samples 1 to 5 have been tested 273 times at 80 percent full charge, and 1,326 times at half power."

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

"The capacity decay of sample 1 after circulation is 10 percent, and the actual electricity in the sample is currently 72 percent. The capacity decay of sample No. 2 after cycling was 10 to 14 percent, and the actual power in the sample was 68.8 percent. The volume decay of sample No. 3 after cycling was 7%, and the sample ......"

"So, the best form at the moment is sample three?" Wu Hao asked

"Yes, from the current test situation, sample 3 has the least volume decay after cycling, and the body is the most stable."

"Seven percent, which is ......"

"Five .six percent, sir!"

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

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

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

Coco still smiled on the screen and nodded 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, in short, 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 increases the energy storage density in a single volume.

Taking two lithium-ion batteries that are also 30 grams as an example, the main lithium-ion batteries on the market at present, 30 grams can hold 1,000 milliampere-hours of power. After Wu Hao's optimization, the same 30-gram lithium-ion battery will have a capacity of 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 was only using the knowledge stored in his head and the joining of the materials that he could currently access to to achieve a relatively ideal result.

Concrete results require further experimental data to be obtained, and the development of a battery is not only based on its capacity, but also on a series of other factors.

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

Take a mobile phone brand as an example, because a mobile phone exploded several times in a year. As a result, the mobile phone brand was greatly affected around the world, and even caused a serious brand trust crisis, and finally the mobile phone manufacturer had to apologize and recruit back all the mobile phones of this brand overseas.

In addition, there is also whether the materials used inside the battery are safe and reliable, whether they are toxic or not, and how much pollution they can cause.

Last but not least, what is the manufacturing cost of this battery, if the cost is too high, it will also lose its competitiveness in the market.
