In Li Mu's view, with the explosive development of human science and technology, battery is a special field that has been hard to break for a long time.

People have been able to condense tens of thousands of tons of computer equipment needed decades ago into the size and weight of a book, and even the computing power has been increased by thousands of times. According to the development speed of computers, now a mobile power battery should be able to drive a two ton car for 2000 kilometers without stopping.

However, the reality is very cruel. The human technology tree has not found a huge technological breakthrough in the field of battery. All mobile devices are plagued by the specific capacity that battery can not break through.

Fifty years ago, how much energy can a kilogram of battery store? Now, the lithium battery has increased by several times at most. It's hard to improve the energy density of the battery. The notebook is equipped with a heavy battery, which can only store energy for a few hours. After more than ten years, the smart phone, which publicizes power saving, basically needs to charge every day. If we follow the development speed of the computer processing chip In the era of Apple mobile phones, the battery should be reduced to the size and weight of only one yuan coins at the same capacity.

It is precisely because the battery industry cannot find a major breakthrough that the service time of lithium battery will exceed everyone's imagination. We have been used to rapid innovation for a long time. Even contemporary scientists believe that in the near future, someone will be able to find a more advanced power storage scheme than lithium battery, but the terrible thing is that lithium battery, like rubber, has become Part of the industry that has always been irreplaceable.

Since the invention of automobile, there have been more than ten thousand technological innovations at home and abroad. People even try to get rid of the fuel tank and the fuel engine. But up to now, no car can get rid of the rubber.

The more so, Li Mu feels more and more that the layout of lithium battery industry should be grasped. While it has not yet become the mainstay of the information age, it is necessary to dig out the source of this industry.

Nowadays, people's life is far away from lithium batteries, and the popularity of mobile phones is not high, so not everyone can touch lithium batteries. But in the future, mobile phones, laptops, tablet computers, rechargeable batteries, cameras, even flashlights, small vibration toys, new energy vehicles, etc., can't leave lithium batteries. Before the advantages of the industry are highlighted, Put resources in your own hands!

……

As always in Harvard campus, as the academic palace, everything here follows its own rules very much, and there is no change. However, the inner Harvard has started to have some elements different from the usual. This is because in the body of Harvard, there is a very new baby. Its name is Facebook.

With Li Mu's funds, Mark Zuckerberg put most of his energy into the incubation of Facebook project. He has no great ambition. In the early stage of entrepreneurship, his greatest wish is to make Facebook popular in Colleges and universities across the United States and become the new favorite of American college students on the Internet.

In order to achieve this goal, Mark Zuckerberg has invested a considerable amount of energy and money to promote Facebook in Colleges and universities across the country. He and his local twitter team plan to travel all colleges and universities in the United States in the next three months, and push Facebook, a new social product for college students.

When Li Mu arrived at Harvard, Mark Zuckerberg just came back from New York, and his team was working in turn at Columbia University and other universities in New York. Because there were so many universities in New York, Mark Zuckerberg attached great importance to it. Before that, he had been staring at New York for more than a week. This time, Li Mu said he would meet himself at Harvard Face, he just hurried back to Massachusetts.

In Mark Zuckerberg's eyes, Li Mu is his boss, so as soon as he arrived at Harvard, he directly came to see Li Mu, who was very excited to report the current development of Facebook to Li Mu.

According to Mark Zuckerberg, at present, Facebook has millions of registered users, more than 100000 daily users, and more than 90% of the users are college students. This is not only because the focus of publicity is on the university campus, but also because college students have more time to contact the network, and there is a great demand for social networking on campus.

Li Mu asked him, "how many college students are there in the United States now?"

Mark Zuckerberg said without hesitation: "at present, the total number of all undergraduate and graduate students in the United States is about 17 million."

Li Mu nodded and said, "you now have millions of registered users, accounting for 6% of your total target group in the first stage. It's a long way to go."

Mark Zuckerberg said: "although it's only 6% now, at our current promotion speed, it can be increased to 30% at most by the end of the year."

"In about half a year, from 6% to 30%, it's a linear growth," said Li, with his chin on

Mark Zuckerberg didn't understand the meaning of Li Mu's words, but vaguely felt that Li Mu might not be too satisfied with his goal, so he tentatively asked him: "President Li, if you have any opinions and unsatisfied places, please point them out directly, and I will try my best to correct them."Li Mu smiled and said, "don't be too nervous first."

After all, Li said slowly, "in the Internet, good product users are growing linearly. Starting from 10000 users, they have crossed 50000, 100000 and 200000 levels, and have grown to millions, tens or even billions."

Mark Zuckerberg agreed: "you're right. It's really the quality of a good product. The total number of users is steadily increasing, and there are few or no bottlenecks."

Li Mu sighed: "but it's just a good product. It's really a great product. Its users should be growing explosively. Its body contains huge energy like nature. As an ancient Chinese poem describes," suddenly like a night of spring breeze, thousands of trees and pears bloom. "Nature never let Harvard or even Massachusetts trees grow one by one A tree with green buds will use its energy to make most of the trees in Massachusetts pull out green buds at the same time in a very short period of time. A few days later, other latitudes and altitudes will successively take a large area as a unit, green up one by one, and the best products should be like nature. "

Li Mu firmly believes that the theory of "excellent products is explosive development", many products occupy the large market quickly in a very short time. This theory is also the rule that Internet explosions must follow. There are legends, QQ, Taobao, tiktok, micro-blog, iPhone, iPad and Android, or even tremble, but Li Mu has no chance to experience. Over one year, the fire has been around tiktok.

Facebook itself is a blockbuster, but it hasn't opened the blockbuster door in the initial stage. Li Mu knows that Mark Zuckerberg will be able to open the door sooner or later, but he still hopes that this day will come faster.

"Great product..." Mark Zuckerberg murmured to himself, thinking of the scene when everything recovers at the same time when spring comes. He has lived for more than 20 years, and has been used to the change of seasons for a long time, so he never felt how shocking things are when everything recovers at the same time. But now, if you think about it carefully, it's really a powerful force behind this Cut, is that power, can let half of the earth bathe in the warm spring wind in a short time.

If behind the global trees and plants, is the powerful nature driving everything, then behind the global Internet users, what is the driving force? Or, how can we have such power?

Mark Zuckerberg suddenly looked at Li Mu, and his mind suddenly opened!

Isn't Li Mu such a force? Since YY, all products have been growing explosively. The number of users of YY does not need to set a stage of 10000, 50000 and 100000 at all. Its development speed is so fast that its stage is based on the number of one million, five million, ten million and fifty million.

Compared with YY, the development speed of Facebook is more than a little slow. I am still running with my team in a university, a school and a school in the United States. At the beginning of Li Mu's attack, it was almost a national attack. The gap between them is so big that people's backs are cold.

Mark Zuckerberg understood that Li Mugang just said that the good product is linear growth, not praising his work results, but implicitly conveying disappointment! If Facebook develops at this pace, it can only be a good product with linear growth, but it can't be a great product with explosive growth.

All of a sudden, Mark Zuckerberg was filled with frustration.

Li Mu saw his loss and didn't offer any consolation. Instead, he asked him, "what's your current promotion rhythm?"

Mark Zuckerberg said: "I first divided the U.S. into several areas, as a large area, and then defined several areas that need to be broken through. For example, in the New York University circle that is being promoted now, one university after another is constantly promoting. Every time I go to a university, I try to mobilize the students of this university to make them interested in Facebook 。”

Li Mu nodded and said: "it's right to do it, but this way is to follow the rules. You always think that every university student is an independent closed-loop, so you have to open it one by one, so I believe that now your Facebook users are also a closed-loop and a closed-loop independent. For example, Harvard students only follow the rules on Facebook People at Harvard interact with each other. MIT students only communicate with MIT students. Although we are almost separated by a wall, on Facebook, we are like two isolated LANs, right? "

Mark Zuckerberg was shocked, and immediately said with shame, "you are right. Now it is true that users are interacting with schools as a unit, rarely breaking the boundaries of schools..."

Li Mu nodded and asked him, "have you ever set off firecrackers?"

Mark Zuckerberg was stunned and asked him, "are you talking about a string of Chinese firecrackers?"

"That's right."

"I played as a kid," Mark Zuckerberg saidLi Mu said: "in China, firecrackers have one hundred rings, one hundred thousand or even one million rings, but their essence is not different. They are all independent firecrackers, and then they are connected together by fuse. They are called firecrackers by themselves. Firecrackers are connected by many firecrackers, so when you light them, they will explode all the time , until the last one is gone. "

After that, Li Mu turned around and looked at Mark Zuckerberg and said seriously, "but now, you are not setting off firecrackers. You are just setting up firecrackers. A university is a firecracker. You run to it, light it, wait for it to blow up, and then go to the next one. In this way, how long will it take you to finish it?"

Mark Zuckerberg looked at Li Mu and murmured, "Mr. Li, do you mean that I need to solve all colleges and universities as quickly as lighting firecrackers?"

Li Mu waved and said, "I mean, you need to make a fuse first."
