Chapter 298: Big project of lithium sulfur battery

Lithium-sulfur batteries are also being made abroad, and have already started a long time.
As an inappropriate but very vivid metaphor, if human civilization lights up this technology tree, 10 technical problems need to be unlocked, and these 10 technical problems can give birth to 100 patents, then foreign research institutions may have established 30 to 40 patents and more.
Under the WTO framework, once a company has formed 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 a rogue, you have no choice but to ask you to publicly authorize your patent.
Because the game is based on the fact that the strengths of the two sides are equal, and when the strengths are not equal, the problem of games does not exist.
The same principle applies to replacing enterprises with countries, except that the main body of action has changed from market share to trade surplus and dependence.
After listening to Lu Lao's request, Lu Zhou froze slightly. After thinking about it for a moment, he replied cautiously: "Although I really want to help you, I just research the anode material, There are not many researches on lithium batteries, and I am afraid it will be difficult to come in handy. "
It wasn't that he was clumsy, he was telling the truth.
Although the modified PDMS film solves the most troublesome lithium dendrite problem, the technical difficulties of lithium-sulfur batteries are not entirely in the lithium anode material.
For example, the first one is the extremely poor electrode cycling performance.
The sulfur cathode does not directly generate lithium sulfide during discharge, but is gradually reduced, with the formation of lithium polysulfide intermediates. Lithium polysulfide will dissolve in most electrolytes, causing dissolution and loss. These dissolved lithium polysulfides are diffused to the negative electrode for reduction, and then oxidized at the positive electrode.
This phenomenon will eventually cause the positive electrode material and the negative electrode to stick together. Although it may not cause safety problems, it will make the entire battery non-recyclable.
And this is the "shuttle effect" of Professor Salot against Professor Krell at the MRS meeting.
If you want to solve this problem, you can start from the positive electrode material or from the electrolyte. Although there are many options, it is not easy to solve.
Half of the drawings that Lu Zhou parsed from the wreckage through the scanning gun have a high probability that the lithium-air battery is far beyond the current level of technology and has jumped at least two steps.
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 does not know whether it is available. Naturally, the problem of "shuttle effect" does not need to be considered.
"Of course this burden will not be placed on you alone," said Lao Lao with a smile. "This research will have more than 20 national scientific research units such as the Institute of Physics and Chemistry Technology of the Chinese Academy of Sciences and the Nanoscience Research Center to invest in projects. In the group, focus on 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, major research units have dedicated research groups to address this. Subject to technical breakthroughs! "
"Speaking of experts in the field of lithium batteries, the professors in our expert group unanimously recommend that you are 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 give priority to it. 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 murmur.
Originally, he thought that Lu Lao was talking about ordinary support policies, but he did not think that the senior management had already done it as a national key project.
If the former is just a short supply for the scientific researchers who are fighting on the front lines, then the latter is equivalent to a "group army" composed of research units at all levels organized by the state will to fight a large-scale Battle.
Outsiders may not immediately feel the impact, but for the industry, this is not a big deal.
For Lu Zhou, this is of course a good thing. Lu Lao's statement is very clear, and he can provide him with the greatest concessions outside of research.
Although he is not short of money, support from the policy side can save him a lot of trouble.
For Lu Lao's proposal, Lu Zhou smiled and nodded.
"If that's the case, of course I'm fine!"
...
Having determined the intention of cooperation, what is discussed next is the specific content of cooperation.
Lu Lao's proposal is to build a material science research institute in the newly-designated high-tech industrial park in Jinling, focusing on the 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 rebate for imported equipment, and three-year new energy research subsidies.
As for funding for scientific research, part of the money is subsidized by the state, and the rest is paid by the enterprise.
At the same time, Jinda can transfer professionals to his laboratory.
Like physics, materials science is also one of Jinda's majors. In the field of organic and nanomaterials, many directions have reached the world's leading level.
Lu Zhou was very satisfied with these conditions.
However, these are not critical.
The focus that most interests him is in the research results.
This is also a question that any researcher will care about.
If it is natural science, it is better to say that there are not so many interests, and the object of any research results is all humanity. But if it is engineering research, the benefited objects will be specific to organizations and individuals in addition to all human beings.
One of the most concrete manifestations is patents.
Regarding Lu Zhou's question ~ EbookFREE.me ~ Lv Laosi thought for a moment and carefully responded: "I am not an entrepreneur, I cannot give you a specific sharing plan. But I can assure you, The achievements you have made in the direction of lithium-sulfur batteries will be guaranteed by the state administration, and they will account for at least 30% of the cooperation with enterprises. "
Under normal circumstances, the vertical issue is that the state will pay you for research. The state does not consider the question of profit and loss, and in principle, it will not let you use the state's money to fatten yourself.
For the horizontal issues of enterprises, most of the results will be taken away by the enterprises. Even if a small number of big cattle can negotiate the conditions with capital, they will never get such a high percentage.
Because scientific research is like gambling, investment is a bottomless pit, and enterprises must bear considerable risks at the same time as funding. Researchers can get 10% of it, and they all pay for the risks themselves.
As for the situation abroad, I remember that an American drama called "The Big Bang Theory" mentioned this topic. In the United States, the results made by the research funds of schools are usually only 25% by professors and 75% by schools. .
And the subject that the company spends money on will require more results.
In contrast, Lu Lao's conditions can be said to be quite favorable, and even to use administrative power to interfere in the market, forcing companies to make concessions.
However, Lu Zhou is not short of money, and he is confident that he will be able to produce results.
After hearing this division ratio, although he knew it was Lu Lao's kindness, he declined it politely.
"I don't need corporate investment, I can fund it myself."
Hearing Lu Zhou's request, Lu Lao laughed heartily.
"That's good to say, if Professor Lu intends to conduct research at his own expense, as long as this institute is built in China, all other preferential policies will remain the same. As for the research results, of course, all of them belong to you!
