Chapter 119: Plugging into the Battery Industry (Part I)
Liu Lin Office of Jiu'an Technology.
"Xiao Liu, you're finally back!"
"What is Academician Zeng? What is it that actually made the general manager of my company call me several times in a row to urge me to come back?" Liu Lin poured a cup of tea for Academician Zeng (who used to be half of his teacher), and looked at the dignified middle-aged man who came with Academician Zeng!
Academician Zeng is a master of Tsinghua University's research on ion batteries, and Liu Lin once did research with him, and he is also half a teacher, so there is naturally no problem with calling Liu Lin like this.
"Xiao Liu, this is Minister Xu, the number one leader of the Ministry of Energy!" Academician Zeng introduced to Liu Lin.
"Academician Xu, can you give me a thorough explanation? What the hell is going on? I'm a little scared when you come over like this. Liu Lin shook Minister Xu's hand, turned his head curiously and asked Academician Xu.
This is strange, what is the Ministry of Energy doing here, whether it is a sewage treatment center or a super processing center, it has nothing to do with the Ministry of Energy, even if it is a mobile phone wireless charger, it doesn't have much to do with it, right?
"It's not a big deal. Academician Zeng glanced at Minister Xu and nodded, and then continued, "Just 15 days ago, our Ministry of Science and Technology, together with a number of ministries and research institutes, jointly issued a white paper on new energy technology research, and established a series of research directions, from solar energy technology to a new generation of battery technology. In order to respond to the call of the national energy development strategy and the outline of the 18th National Congress of the Communist Party of China, Tsinghua University is one of the best schools in China, and we must be the pacesetter. ”
Liu Lin was stunned, where is this, what are you looking for me?
"We Tsinghua integrated a series of resources, and major enterprises jointly established a lithium battery scientific research project, with a total investment of 680 million RMB. ”
"When I chatted with Minister Xu two days ago, because before, when you were doing research with me, all kinds of abilities were very comprehensive, and many suggestions were very targeted, plus you created Jiu'an Technology, and you can be in the limelight recently, so I specially mentioned you, and Minister Xu planned to come and sit with you!" After speaking, Academician Zeng looked at Liu Lin and smiled kindly.
"Sit down?" ", are the current leaders so idle? There is nothing to sit and sit, Liu Lin is completely confused this time, where is this?
"Mr. Liu, I'm sorry to disturb you!" Minister Xu saw Liu Lin looking at him, knowing that he was out of the horse and said seriously: "Mr. Liu, that's the case, energy development is the top priority of China's industrial production, and before that, it has always been a foreign country that controls the right to speak, and our country is just a bystander." ”
"In order to implement our Huaguo manufacturing A868 plan, our country needs batteries with higher performance and higher storage capacity, preferably low-cost and mass-produced, with a simple production process and high recycling times. ”
"When chatting with Academician Xu, he strongly recommended you, plus your company has its own research institute. So I'm going to talk to you today to see if it's possible for you to get involved in this project. ”
"So what kind of battery do you recommend, lithium battery or nickel separator battery, or lithium polymer battery. Liu Lin doesn't know much about the direction of batteries, but he still knows the mainstream batteries on the market.
"Whether it is a lithium battery or a lithium polymer battery, it has its limitations, and after the lithium battery cell is overcharged to a voltage higher than 4.2V, it will start to have side effects. The higher the overcharge voltage, the higher the danger. ”
"As soon as the voltage is higher than 4.2V, less than half of the lithium atoms remain in the cathode material, and the storage compartment often collapses, resulting in a permanent drop in battery capacity. If the charge is continued, the storage compartment of the negative electrode is already filled with lithium atoms, and the subsequent lithium metal will accumulate on the surface of the negative electrode material. ”
"These lithium atoms grow dendritic crystals from the surface of the anode in the direction where the lithium ions come from. These lithium metal crystals pass through the diaphragm paper, shorting the positive and negative electrodes. Sometimes the battery explodes before the short circuit occurs, because during the overcharging process, the electrolyte and other materials will crack to produce gas, which will cause the battery shell or pressure valve to bulge and rupture, allowing oxygen to enter and react with the lithium atoms accumulated on the surface of the negative electrode, and then explode. ”
"Whether it is a lithium battery or a lithium polymer battery, there will be such limitations. ”
"Therefore, after a lot of research and negotiation with the company, we took into account the life, capacity, and safety of the battery. The future development of batteries is definitely graphene batteries. Graphene battery is a new energy battery developed by using the characteristics of lithium ions to shuttle rapidly and heavily between the graphene surface and electrodes. ”
"If the experimental stage of the new graphene battery is successful, it will undoubtedly become a new development point for the battery industry. Battery technology is the biggest threshold for the vigorous promotion and development of electric vehicles, and the battery industry is in the stage where the development of lead-acid batteries and traditional lithium batteries have encountered bottlenecks. We will also occupy the bridgehead of energy.
"However, after consulting with the industry, the feedback they gave us was that there were still many theoretical problems to be solved in order to produce this kind of battery. Not to mention the high cost, safety is also difficult to guarantee. ”
"Minister Xu, what do you mean?" Although Liu Lin somewhat understood what Minister Xu meant, he still had to confirm it.
Before there was no self-protection ability, Liu Lin has always avoided not participating in these key industries, not managing mobile phone wireless chargers, or sewage treatment centers, and not touching the cake of those oligarchs.
"Although we do not seek hegemony, we will never allow others to establish all kinds of patent barriers on the platform of international trade, sniping at the development of our new energy, and now countries are frantically registering various patents. ”
"In the current situation of global integration, once a certain country or any company forms a patent barrier in a field that cannot be bypassed, it is an extremely passive thing for our country. ”
"For example: in the field of chips, the most obvious is Qualcomm in country M, and now it can be said that the whole world's mobile phone chips are his enclosure of sheep, and he harvests wool at will, and we have no way to pinch him, which can be said to be helpless. ”
"Now it is not a business, or the game between the country and the car is based on the situation of equal strength between the two sides, if the difference in strength is too large, then there is no game but a one-sided negotiation. ”
