Start from 1980

Chapter 420 A New Possibility

Because later generations, hundreds of international intellectual property patents for lithium batteries are owned by Japan and the United States.

As for whether the lithium battery can be turned into the power source of the car, this is not in the scope of Su Chen's consideration. His consideration is in the notebook, mobile phone tablet and other mobile products that need to use lithium batteries.

Although some people think that Tesla's cars are awesome, in 1966, Ford had already made charging cars.

He even invented the sodium-sulfur battery—a battery with a new chemical system consisting of a liquid sodium polysulfide positive electrode, a liquid metal sodium negative electrode, and a solid electrolyte.

An electric car equipped with a lead-acid battery can run up to 64 kilometers, while a Ford sedan replaced with a sodium-sulfur battery can easily run 320 kilometers, and then charge for an hour, and can continue to drive another 320 kilometers!

Isn't it awesome?
But Ford's electric car dream turned into a piece of paper after all, because the working temperature range of the solid electrolyte of the sodium-sulfur battery must be kept at 300 to 350 degrees Celsius.

Combined with the technical level at that time, it is known that the diaphragm cannot bear such a high temperature at all, and the melting point of sodium is 98 degrees, and it will burn when it encounters air.

Although electric vehicles were short-lived in the 60s, their impact was far-reaching.

Since then, whether it is the Atlantic or the Pacific Ocean, whether it is governments, corporate giants or research institutions, as well as physicists, materials scientists and chemists, they have begun to explore a new unknown field with great enthusiasm. : A better rechargeable battery.

In this lithium battery industry with extremely high technical threshold, whoever owns the patent representing the core technology means that he has the scepter to rule the entire industry.

The establishment of the strongest legal department is also to deal with possible patent issues.

After finalizing the next development, Su Chen's mood also became more relaxed. He had a leisurely time every day, going out for a walk with his two girlfriends from time to time, having fun together, and then calling two Hollywood people.

It's so leisurely.

……

Today, I just came back from get out of class.

I saw the little secretary was chatting with Cao Jiaxin and an old man in good spirits.

Seeing Su Chen came back, Cao Jiaxin and the little secretary hurriedly greeted: "Boss, good afternoon, Miranda, Avril, good afternoon."

"Hi, hello." The three nodded in response.

"Boss, let me introduce you, this is Professor Goodenough." Cao Jiaxin introduced, "I just came back from England."

"Hello Professor."

Su Chen hurriedly stretched out his hand. In his eyes, this old man had a blingbling aura all over his body.

This old man is really not interested in money. He participated in World War II. Maybe life and death have long been indifferent.

So it was later called the 'father of lithium batteries'.

Cao Jiaxin introduced again: "Professor, this is our boss, Su, these two are his girlfriends."

"Hello Professor, I'm Miranda."

"Professor, welcome to our house as a guest, I am Avril Lavigne."

After a brief greeting, Professor Goodenough said straight to the point: "Su, I heard that you have some experience in lithium batteries, so I came back from England in advance, mainly to meet you."

"Hi, professor, you are an expert in this field, so I won't lie to you." Su Chen said, "Actually, I don't have any experience, and I mainly want to invite you to join my laboratory."

Cao Jiaxin's face was blank for a moment.

When I originally went to the UK, the boss also said that he had experience in lithium battery research.

As a result, when the old man came back from England, the boss actually said that he was lying to him?
Professor Goodenough was not angry, but asked, "Then where is your laboratory?"

"It hasn't been established yet." Su Chen said seriously: "I'm waiting for your professor to help, because you are an expert in the field of lithium batteries."

"Then why should I join your lab?" Professor Goodenough asked.

Su Chen instantly turned to Teacher Ma: "Since the oil crisis, I think we should develop a new type of energy product to replace oil.

However, whether it is a sodium-sulfur battery, a lithium battery invented by Whittingham, or a lithium cobalt oxide battery invented by Professor You, no suitable negative electrode material has been found, resulting in the inability to popularize its usability and serve the general public. "

"Professor, although the lithium cobalt oxide battery you invented has many advantages, it also has many disadvantages."

Professor Goodenough nodded: "There is indeed this problem, so this time I returned to the United States early, just because you said you have experience in lithium batteries, buddy, you can't see me as an old man, just lie to me."

"Professor, how dare I lie to you?" Su Chen said, "I can't provide conditions like Oxford University or any other university that allow you to teach students, but I will provide you with first-class research conditions.

Research on lithium batteries with advantages such as low cost, high charge and discharge efficiency, long service life, and high thermal stability. "

"However, it's hard to impress me like this." Professor Goodenough shook his head: "Dude, I don't know anything about you. I can't just join your laboratory just because of your casual words, right? What's more, your There is no prototype of the laboratory now."

Well, talents with high technology are indeed rare.

Su Chen said: "Professor, if you pay attention to the news in the United States, you will know that Fox in Hollywood has changed. I am the new boss, and I am also the new boss of Acorn, which is engaged in chips in the UK."

"Are you the mysterious buyer?" Professor Goodenough looked at Su Chen seriously.

Su Chen nodded, then took out the papers he had published, and continued: "I also published these papers."

Goodenough took it seriously.

After a long time, he said, "Then are you a student or a businessman?"

"I'm a student and a businessman." Su Chen said, "And I really want to research this new type of energy. In addition to not being able to teach students, I will create a first-class laboratory for you and use [-] million US dollars as the start of this project. funds!"

"One hundred million dollars?"

Not only Professor Goodenough was shocked, but also several girls present.

Su Chen nodded: "Yes, you also know that Japan Benzene and us are feuds, and now Sony is using the patents developed by the professor to do things in this area, so I am also going to enter it."

"The conditions are really attractive." Professor Goodenough thought about it seriously, and said, "Man, I need to think about it."

"Then I'll wait for your reply, professor." Su Chen said: "In addition, I think of a possibility that needs to be verified by people, if we use the lithium iron phosphate naturally formed in the lithium iron phosphate mine, or we synthesize lithium iron phosphate by ourselves , arranged in an olivine-like crystal structure."

"Then use 1% carbon to coat the lithium iron phosphate as the positive electrode of the battery. Can it solve the problem that the lithium iron phosphate material has poor electrical conductivity and is not suitable for high-current re-discharge?"

"At the same time, if we use carbon instead of metal lithium as the negative electrode of lithium batteries, will it make lithium batteries safer? Looking at the world, only you are an expert in this field, so I especially want to invite you to come Test this idea."

Although Su Chen doesn't know how to do it, he has a vague memory of it.

But just having a memory does not mean that a lithium battery with high safety can be developed immediately. At most, it can only make people avoid detours.

It will take at least three to five years to study it.

But as long as it can stay ahead of Sony and Bell.

After all, the two companies are still figuring it out.

Hearing this, Professor Goodenough's eyes lit up: "Man, your idea is very constructive. I want to join your laboratory. When will we start the laboratory?"
