Chapter 299 Lithium-Sulfur Battery Project

Lithium-sulfur batteries are also being made abroad, and it has been started for a long time.

To make an inappropriate but vivid metaphor, if human civilization needs to unlock 10 technical problems to light up this technology tree, and these 10 technical problems can produce 100 patents, then foreign research institutions may have established 30 to 100 patents. 40 patents and more.

Under the framework of the WTO, once a certain company forms an insurmountable patent barrier in a certain field, it will be in an absolute advantage for other companies.

For example, in the field of chips, Qualcomm has successfully become the father of other 3C manufacturers. Even if you are so rogue that you are required to publicly authorize your patents, you have nothing to do.

Because the game is established when the strengths of the two parties are equal, and when the strengths are not equal, there is no such thing as a game.

The same rule applies when an enterprise is replaced by a country, except that the main body of action changes from market share to trade surplus, dependence and the like.

Hearing Mr. Lu's request, Lu Zhou froze for a moment, and after thinking about it for a moment, he replied cautiously: "Although I really want to help you, I just do some research on negative electrode materials, and the whole There are not many researches on lithium batteries, and I am afraid it will be difficult to use them.”

It's not that he is hiding his clumsiness, what he said is all the truth.

Although the modified PDMS film solves the most troublesome lithium dendrite problem, the technical difficulty of lithium-sulfur batteries is not entirely on the lithium negative electrode material.

For example, the first one is that the electrode cycle performance is extremely poor.

The sulfur cathode does not directly generate lithium sulfide during discharge, but is gradually reduced, accompanied by the formation of lithium polysulfide intermediates. Lithium polysulfide will dissolve in most of the electrolyte, and the dissolution loss will occur. These dissolved lithium polysulfides will diffuse to the negative electrode for reduction and then oxidize at the positive electrode.

This phenomenon will eventually cause the positive electrode material and the negative electrode to stick together. Although it does not necessarily cause safety problems, it will make the entire battery non-recyclable.

And this is the "shuttle effect" that Professor Sarot criticized Professor Krell at the MRS conference.

To solve this problem, you can start with the positive electrode material or the electrolyte. Although there are many choices, it is not easy to solve.

The half-sheet blueprint that Lu Zhou analyzed from the wreckage with a scanning gun is likely to be a lithium-air battery that is far beyond the current technological level, and it has jumped at least two ranks.

Although lithium-air batteries are also suitable for lithium as the negative electrode, they do not use sulfur as the positive electrode, and even the electrolyte is not known. Naturally, there is no need to consider the issue of "shuttle effect".

"Of course this burden will not be placed on you alone," Mr. Lu said with a smile. In the group, focus on tackling various technical difficulties in the field of new energy. Lithium-sulfur batteries are an important part of our new energy strategic layout. In addition to you, all major research institutes have special research groups for this The subject is going to be technically tackled!"

"Speaking of experts in the field of lithium batteries, the professors in our expert group unanimously recommend you as the most suitable candidate. We are not asking you to change your research plan, but we hope that if you have a new research plan, you can be given priority The direction of lithium-sulfur batteries. Whether you want people or money, we will do our best to meet your conditions!"

Hearing this, Lu Zhou couldn't help but secretly stunned.

Originally, he thought that what Lu Lao was talking about was just an ordinary support policy, but he didn't expect that the high-level officials had already regarded it as a national key project.

If the former is just an empty supply for scientific researchers fighting on the front line, then the latter is equivalent to organizing a "group army" composed of research units at all levels by the will of the state to fight a large-scale battle in the field of new energy. battle.

Outsiders may not be able to immediately feel the impact of this, but for industry insiders, this is not a big deal.

For Lu Zhou, this is of course a good thing. Lu Lao said very clearly that he can provide him with the greatest discount in places other than research.

Although he is not short of money, support from the policy side can save him a lot of trouble.

Regarding Lu Lao's proposal, Lu Zhou nodded with a smile.

"If that's the case, of course I'm fine!"

...

After confirming the intention of cooperation, the next discussion is the specific content of cooperation.

Mr. Lu's proposal is to build a materials science research institute in the newly designated high-tech industrial park in Jinling, focusing on research and development of lithium-sulfur battery-related technologies. At the same time, the state will provide preferential policies such as five-year tax exemption, tax rebates for imported equipment, and three-year research subsidies for new energy projects.

As for scientific research funding, the state subsidizes part of the money, and the rest is paid by enterprises.

At the same time, Jinda can provide professional talents for his laboratory.

Like physics, materials science is also one of King University's advantageous majors. In the field of organic and nanomaterials, many fields have reached the world's cutting-edge level.

Lu Zhou was very satisfied with the conditions offered by Mr. Lu.

However, these are not critical.

What concerned him the most was the research results.

And that's a question any researcher would care about.

If it's natural science, it's okay to say that there are not so many stakes, and any research results will benefit all human beings. But if it is engineering research, the beneficiaries will not only benefit all human beings, but also specific organizations and individuals.

One of the most specific manifestations is patents.

Regarding Lu Zhou's question, after thinking for a while, Mr. Lu replied cautiously: "I am not an entrepreneur, so I can't give you a specific sharing plan. But I can assure you that you are in the direction of lithium-sulfur batteries. The results made will be guaranteed by the state administration, and it will account for at least 30% of the cooperation with enterprises."

Under normal circumstances, the vertical project is that the state pays for your research. The state does not consider the issue of profit and loss, and in principle it will not allow you to enrich yourself with the state's money.

As for the horizontal projects of enterprises, most of the results produced will be taken away by enterprises. Even if a small number of big cows can negotiate terms with capital, they will definitely not get such a high ratio of 30%.

Because scientific research is like gambling, and investment is a bottomless pit. Enterprises bear considerable risks while bearing funds. Researchers can share 10% of their own money to share the risks.

As for the situation in foreign countries, I remember that an American TV series called "The Big Bang Theory" mentioned this topic. In American universities, the research funds made by the school are usually only 25% for professors and 75% for schools. .

And the subject of the company's spending will require more results.

In contrast, the conditions offered by Mr. Lu can be said to be quite generous, and it can even be said that he used administrative power to interfere in the market and force the company to make concessions.

However, Lu Zhou is not short of money, and he is sure that he will be able to produce results.

After hearing about the ratio, although he knew it was Mr. Lu's kind intentions, he still politely declined.

"I don't need corporate investment, I can fund it myself."

Hearing Lu Zhou's request, Old Lu smiled heartily.

"That's easy to say. If Professor Lu plans to do research at his own expense, as long as the research institute is established in China, all other preferential policies will remain the same. As for the research results, of course they all belong to you!"
