The technological empire begins with polymer materials - Chapter 73 Solid-state battery! Unbridled!

When Gao Yuan showed the original battery design drawing, the conference room quickly became quiet, and the company’s researchers began to discuss it privately.

“Researching batteries? We are a chemical fiber company, so the span of developing batteries is too big, right?”

“See clearly, okay? It’s not a matter of span at all.”

“Then what’s the problem?”

“Of course it is Mr. Gao’s design. How can there be such a battery in the world? Without electrolyte, it means ultra-high density. When the battery is fully charged, atoms will inevitably expand inside the battery. Without electrolyte as a buffer, how can Prevent the danger caused by excessive expansion? How to prevent the detachment of atoms caused by repeated contraction?”

“this…”

“It seems reasonable. Brother, you used to study batteries?”

“No, I follow Teacher Li Changxing to do vulcanization technology. Batteries are purely a personal hobby.”

“To be honest, I’m not very optimistic about Mr. Gao’s design. So far, the most advanced technology in the world is Panasonic’s semi-solid-state battery, and Mr. Gao’s plan is completely stupid and will directly enter the all-solid-state era. “

“But having said that, President Gao’s foundation is really good. He actually studies electrical and chemical engineering?”

Unconsciously, Kunlun Company has become a large-scale enterprise with a Ru0026D team of 400 people. At this moment, everyone is talking about it, but in the final analysis, they generally feel that the probability of success in battery research is not very high.

Xu Qingzhou frowned slightly and asked Gao Yuan, “Is this a solid-state battery solution?”

Gao Yuan nodded, “Yes, the lithium battery technology we are currently using is approaching the physical upper limit. The price may decrease with mass production, but the capacity is difficult to exceed 500 watt hours per kilogram.”

Energy-to-weight ratio is an extremely important data in the battery field.

To put it simply, 500 watt-hours per kilogram means that each kilogram of battery can store up to 0.5 kilowatt-hours of electricity. If you want your electric car to hold 100 kilowatt-hours of electricity, you need to stuff 200 watt-hours into the car body. kg battery.

Li Changxing asked curiously from the side: “Excuse me, Mr. Gao, what is the approximate capacity of your solid-state design?”

Gao Yuan pondered for a moment, “According to my preliminary calculations, it is conservatively estimated that it will not be less than two kilowatt-hours per kilogram.”

Huh~

As soon as these words came out, everyone was stunned. It took a full minute before they woke up as if from a dream.

“Two kilowatt hours per kilogram? This is too high, how is it possible!”

“Yes, currently the 811 model with the highest capacity of ternary lithium can only achieve 300 watt hours. Mr. Gao’s design is nearly seven times that of the 811 lithium battery!”

“Ternary lithium has been calculated, and lithium iron phosphate is generally just over 200 watt hours.”

“Although Mr. Gao’s design is a bit out of the ordinary, it won’t increase the capacity so much, right?”

In the face of doubts, Gao Yuan was well prepared. He released a new chart, which shows the current technical routes adopted by major manufacturers, as well as the production scale.

The so-called 811 ternary lithium battery actually contains 80% nickel, 10% cobalt, and 10% manganese in the positive electrode of the battery.

At the beginning, the ratio of positive electrode elements was actually 523, and later evolved to 622, and was finally shaped into 811. It is recognized by the battery industry that the 811 ternary lithium battery is currently the most technologically advanced and highest-capacity solution.

The disadvantage of 811 batteries is that they are not so safe.

Someone once compared CATL’s 811 ternary battery with BYD’s lithium iron phosphate blade battery. The same puncture caused battery damage. The blade battery was basically fine, but the 811 ternary battery caught fire.

Gao Yuan said solemnly: “From this picture, it is not difficult to find that domestic battery manufacturers are already technically on par with the world’s first-tier companies led by Panasonic, and in terms of output and market share, they have already surpassed them!”

“Just a few years ago, we didn’t have so many excellent ternary lithium power battery manufacturers. Now we not only have excellent manufacturers such as CATL, BYD, Guoxuan Hi-Tech, Funeng, etc., we have also completed the production of battery raw materials and components. to the construction of the entire battery production and assembly industry chain!”

“Times are really different. At least in the field of batteries and new energy, we don’t need to belittle ourselves. Whether it’s Tesla, Mercedes-Benz or BMW’s plug-in cars, if you take them apart, there are hundreds of things inside. Seventy or eighty percent of them are masterpieces of the domestic industrial chain. The so-called chips rely on Infineon, the batteries rely on Panasonic and LG, and the electronic controls rely on Continental and Denso. That is all old history. Nowadays, it is not possible to use domestic products. Shame on you!”

“Next, I will tell you about my plan. Please watch the projection.”

As the screen flickered, everyone saw clearly the internal structure of the solid-state battery, which turned out to be composed of countless billions of orbits! The whole is honeycomb shaped!

The diameter of these honeycomb tracks is less than 100 nanometers, ensuring that the lithium metal is completely fixed when the battery is running. It will not de-electrify and touch ions, and there will be no side reactions to form a passivation film.

According to Plateau’s design, solid-state battery cathodes will no longer use nickel and cobalt. These two metals are not only expensive but also highly toxic. Plateau proposed using manganese and oxygen ions as cathode materials.

The problem is that during the battery reaction, oxygen ions will become fluid, which may cause them to escape from the positive electrode, so molten salt needs to be used to coat the surface of the oxygen ions.

Generally speaking, Gao Yuan plans to use the polymer material technology that Kunlun Company is good at to build countless honeycomb nano-orbitals inside the battery to control the dispersion of lithium metal. In this way, the reaction can be completed within the orbits, and the traditional electrolyte is Give up completely.

On the other hand, Plateau has also improved the battery cathode, using cheaper but better-performing manganese and oxygen ions.

As a result, solid-state lithium batteries have achieved higher density, safer, and cheaper, three seemingly impossible major improvements.

Phew~

The students who understood the plateau technical route couldn’t help but gasp.

“I really did it! Mr. Gao really did it!”

“The nanorail is an innovation in the battery structure. The introduction of manganese and oxygen ions is a material innovation. Coating the oxygen ions and forcing them to become stable is a process innovation! Our boss is very powerful, far more powerful than imagined!”

“According to you, the boss’s plan works?”

“It’s definitely fun! It’s so fun!”

“If this kind of solid-state battery can be made, the range of electric vehicles will not be hundreds of kilometers, but thousands of kilometers!”

“The more important applications are in heavy-duty trucks and ocean-going vessels! If even these equipments use electricity, my God, the picture is so beautiful, I can’t even imagine it!”

As a result, the conference room was completely boiling.

Everyone thought that Gao Yuan was just proposing an idea, and ultimately it was up to his researchers to find a solution.

As the saying goes, if the boss talks, the employees will break their legs. This is probably what it means.

But what everyone never expected was that Gao Yuan not only put forward ideas, but also gave specific solutions!

This is really amazing. The design of solid-state batteries is so unconstrained. Who knows how Gao Yuan came up with it!
