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, 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 run around a thousand kilometers, while most pure electric new energy vehicles can only run a few hundred kilometers, making it difficult for consumers to reduce their range anxiety.

In order to solve range anxiety, the upper limit of energy density of batteries 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, while reducing 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%.

About minutes.

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 belongs to the 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. There are obviously 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 Academy of Science and Technology. We spent who knows how much money to build it later. 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, understood 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'm afraid it would be a big deal.

An extremely good strategy in the short term.

And even if we can't get first-hand technology, Ningde Times will definitely not want BYD to get this technology. If Ningde Times seizes the decentralization of this technology, it will definitely sell products.

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, and whether he could 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, while reducing work items.

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 different volume energy density than liquid lithium batteries due to a different approach to materials. In the first phase of experiments, it reached 700Wh/kg. When today’s battery technology is launched, the graphene

Enene solid-state batteries can easily support new energy electric vehicles with a driving range of 1,500 kilometers. If the technology of the cooperative manufacturers is excellent, the actual driving range of 2,000 kilometers can also be overcome.

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 fire or even explosion. Although the blade battery is safe enough, due to the special structural design, a single battery

When there is a problem with the unit, there is a chance that the total battery of the blade battery will have a limited problem, which can easily cause the tram to lose power at some point, causing it to collapse while driving.

Jiuzhou solid-state batteries using sulfide and graphene materials are not only non-flammable and non-corrosive, but also solve the problem of lithium dendrites. With top safety performance, graphene material films and some specially manufactured packaging materials,
