Chapter 1138 Technology

Ningde Battery's top executives and technical executives are now like primary school students sitting in a classroom listening to lectures. Not only do they not dare to desert, their eyes are wide open, and they are afraid of missing any news.

“At present, both academic circles and battery manufacturers are increasingly aware of the limitations of lithium batteries. That is, subject to the properties of the material, the energy density of lithium batteries cannot be improved by leaps and bounds, and new energy electric vehicles need to enter the market. The mileage support is getting bigger and bigger.

Top-end batteries can only travel around a thousand kilometers, while most pure electric new energy vehicles can only travel hundreds of kilometers, making it impossible for consumers to easily reduce their range anxiety.

In order to solve range anxiety, the upper limit of battery energy density must be increased, which means that new materials must be used to reform everything.

Compared with ordinary liquid lithium batteries, solid-state batteries inherently have higher energy density, smaller size, and safer properties due to the advantages of materials.

This time, our company has developed the second-generation commercial solid-state battery technology. Its solid-state battery can increase the battery life of current new energy electric vehicles by at least three times and reduce the charging time by half. For example, BYAT's new battery can Fully charged in ten minutes, Ningde era’s Kirin battery can quickly charge 80% of its power in ten minutes.

But if we use our battery technology system, we can perfectly solve the charging problem in ten minutes, changing the time spent playing mobile games into reading a few chapters of novels. The time to quickly charge 80% of the battery can even be compressed to 80%. minutes or so.

At the same time, based on the addition of new carbon-based materials and graphene materials, solid electrolytes are used to replace the electrolytes and separators of traditional lithium-ion batteries.

In the early stages of research and development, professors from Xia Ke Academy were also thinking about how to choose the direction of solid-state batteries, because solid-state electrolyte materials include solid-state battery polymers, oxides and sulfides. Among them, polymer electrolytes are organic electrolytes, and oxides and Sulfide is an inorganic ceramic electrolyte.

Among these three electrolytes, polymer has low room temperature conductivity and is inherently unsuitable for use on trams, so it was rejected by us very early.

The oxide cycle performance is good and is suitable for thin film structure design. Currently, friends from Ningde Times, BYD and other companies are on this route this week. The technical barriers are high, but it is safe enough.

The first road is not suitable, and there are too many people on the second road, so the experimenters in our Titan Star Department and the old academicians from the Xia Ke Academy are like heartless young people. Take the initial billions of resources and rush towards the third path.

To be honest, I don’t know why there are so many stupid young people among the company’s R&D staff. Obviously there are academicians who explain these paths very straightforwardly during lectures, but after class, these academicians also accompany these experimental personnel. Crazy. "

When he said this, Gu Qing shook his head in distress.

But the pride in his words was beyond words.

At the same time, many corporate executives and R&D personnel also read between the lines of his words.

Our battery project at Jiuzhou Technology cost billions in the initial stage of research and development, and we also had a bunch of academicians and senior R&D personnel from the Xia Ke Academy of Sciences. I don’t know how much money was spent later to build it. The other assembly plants and the total business planning funds have just been Enterprises with over 10 billion yuan should not touch porcelain technology.

At least Lei Jun, who was looking excited at this time, heard this meaning.

He focused his eyes on the young man on the stage, and he was even thinking in his heart: He had made a statement in Yanjing before and made tens of billions of investments. If he could directly spend money to get the technology from Jiuzhou Technology, I am afraid it would be a big deal. An extremely good strategy in the short term.

And even if Ningde Times cannot get first-hand technology, Ningde Times will definitely not want BYD to get this technology. Ningde Times will definitely sell products if Ningde Times seizes the decentralization of this technology.

Money comes into play at this time.

While thinking about it, Mr. Lei was already estimating how many billions of funds he had left in his pocket to support the rice new energy vehicle to obtain the new technology products of Jiuzhou Technology.

At this time, Gu Qing stretched out his right hand and lightly tapped the battery pattern in front of him. The latter's Yunjin display screen began to enlarge the pattern, and then the structure of the battery was publicly dismantled.

The technologies that can be released for commercial use are all patented technologies. In a sense, they can already hold on to the pipa and half-cover their faces.

Gu Qing pointed to the internal materials of the solid-state battery and said: "Although the third route is the most difficult, compared to polymers and oxides, the conductivity of sulfides is generally the highest in its class, and even has the potential to exceed organic electrolytes.

I heard that the single energy density of Guoxuan Hi-tech's high-nickel ternary battery has exceeded 302 watt-hours per kilogram. However, Tesla's boasted 4680 has not only not produced a stable and mature product after many years, but even has an energy density of 300 watts. This parameter per kilogram per hour is already behind the batteries of our domestic manufacturers in Daxia, which is really a mistake.

In addition, by using sulfide as a material for solid-state batteries, our scientists can naturally save a large part of the design and development of thermal management systems and safety management systems in the development of traditional battery systems during system integration, reducing work items while also The process of battery production, manufacturing and assembly is reduced, which greatly improves battery production efficiency.

The second generation of commercially available graphene solid-state batteries has a higher volume energy density than liquid lithium batteries due to the new material approach. In the first phase of the experiment, it reached 700Wh/kg. When this set of battery technology is implemented today, the graphene solid-state battery can easily support the new energy electric vehicle with a range of 1,500 kilometers. If the technology of the cooperative manufacturer is strong, the actual range of 2,000 kilometers can also be achieved.

At the same time, I need to emphasize the safety of the battery. The solid electrolyte developed by our scientists can effectively block the growth of lithium dendrites. Lithium batteries are prone to battery fires and even explosions. Although the blade battery is safe enough, due to the special structural design, when a single battery unit has a problem, the total battery of the blade battery has a probability of being limited. It is very easy to make the electric vehicle lose power at some point, and thus break down during driving.

The Jiuzhou solid-state battery using sulfide and graphene materials not only has a non-flammable and non-corrosive solid electrolyte, and solves the lithium dendrite phenomenon, but also has top safety performance. The graphene material film and some specially manufactured packaging materials can allow our solid-state batteries to easily withstand thousands of bending tests, and the performance is basically not attenuated.
