If you cheat, money will follow

The first day of National Day.

Chang Le and Jiang Xia packed their luggage and prepared to travel.

For this trip, Jiang Xia spent a lot of energy and made a detailed strategy.

Today is different from the past. She is no longer a free and undisciplined person, and her time is limited.

About to go out, a phone call disrupted their travel rhythm.

The call was from Zeng Xi.

On the phone, Zeng Xi told Chang Le that there was good news from Pingtou Ge Research Institute:

Dr. Shu Zhijie, a student of Liu Chaoyang, led the research team to achieve a breakthrough in the project.

The institute studies many projects.

For general project breakthroughs, Zeng Xi would not alarm Chang Le.

If Zeng Xi can take the initiative to inform him, it means that this project is of great significance.

After ending the call, Chang Le said to Jiang Xia:

"Sorry, I have to go to the institute for a visit, which may take some time."

"It's okay, work is more important. We will leave when you come back." Jiang Xia said with a chuckle.

Chang Le was about to go out, but Jiang Xia stopped him:

"Wait a minute, let me help you change clothes. Wearing a T-shirt and board shorts is really impolite when you go to meet the scientists."

"Oh, that's right, I forgot."

Chang Le put on formal clothes and rushed to Pingtou Ge Research Institute as quickly as possible.

Enter the laboratory through layers of security access control.

inside the laboratory.

Shu Zhijie held a palm-sized square block and introduced it to Zeng Xi and Yu Chengdong.

Next to him, Liu Chaoyang looked proud.

"Mr. Zeng, Mr. Yu, this is the oxide all-solid-state battery we developed based on the ideas provided by the teacher."

"It has strong characteristics such as high energy density, good safety performance, and high number of cycles."

"In terms of energy density, the unit energy density has reached 400wh/kg, which is twice that of the current mainstream ternary lithium batteries and three times that of lithium iron phosphate batteries."

"Under the same quality conditions, it can double the cruising range and easily exceed 1000 kilometers of cruising range on a single charge."

"Moreover, it is estimated that there is still a lot of room for improvement in energy density. By constantly adjusting the material ratio, the upper limit of energy density can be 1000wh/kg."

"We are studying and optimizing the new material ratio and hope to reach the upper limit of 1000wh/kg as soon as possible."

"In terms of safety performance, experiments have shown that the oxide solid electrolyte we developed has very strong chemical and electrochemical stability."

“Even if the rate performance is improved and the electrochemical system is radical, it still will not produce lithium dendrites.”

"The electrolyte made of this material naturally avoids the possibility of lithium dendrites, and there is naturally no risk of internal short circuit."

"The cycle life is long, it can be cycled normally 2000 times, and the service life is more than 10 years."

"According to our experiments, more than 2000% of the capacity is retained after more than 90 cycles, and more than 3000% of the capacity is still maintained after more than 80 cycles."

"In addition..." Shu Zhijie saw Chang Le walking in and paused the introduction:

"boss."

Everyone turned around and automatically gathered around Chang Le.

Shu Zhijie was about to introduce the performance of the battery to Chang Le again, but Chang Le waved his hand and said:

"Dr. Shu, no need, I just heard it. According to Dr. Shu's introduction, then this product can already leave the laboratory?"

"Boss, from a technical point of view, it can be regarded as leaving the laboratory." Shu Zhijie explained:

"Because the technical problems of oxide electrolytes have been overcome, the safety problem of lithium dendrite growth has been fundamentally solved."

"But the cost remains high..."

"The current cost of liquid lithium batteries is US$680/kwh, while the cost of our all-solid lithium batteries is around US$1500/kwh, which is difficult to be accepted by the market."

"So, further research is needed to reduce costs."

"Strictly speaking, this should be the eve of commercialization."

After Chang Le listened, he looked at Zeng Xi: "Sister Zeng, what's your opinion?"

"Boss, the battery industry market size is currently in the hundreds of billions of US dollars, and it can be estimated to reach a trillion US dollars in the future. This project is of great significance to our company..."

"But from a market perspective, even if the cost is controllable, now is not the best time to launch the product."

"Although the country has launched macro policies such as the "Planning Outline" and "Promotion and Application Catalog" this year to guide it, and has implemented new energy subsidies in some areas."

"But from the perspective of market acceptance, it will take some time to cultivate."

"As of the end of August, the total domestic sales of new energy vehicles were less than 8, which is a marginalized product."

After Zeng Xi finished speaking, Yu Chengdong continued:

"Boss, I very much agree with Mr. Zeng's point of view. This technology is very important to us and must be mastered."

"But on the one hand, the market is not mature enough, and it will take a long time for consumers to accept it;"

"On the other hand, Leda Automobile is not ready yet. The new energy division's motor and electronic control research and development has made progress, but it has not yet launched relatively mature products."

After listening to several people's opinions, Chang Le asked Liu Chaoyang:

"Academician Liu, how is the progress of other countries and R&D institutions?"

Liu Chaodong said: "Boss, although many institutions around the world value the prospects of the solid-state battery market and invest in research and development, the progress is not great and there is still a long way to go before commercialization."

"Based on the current situation, no substantial progress has been made in the three technical routes of sulfides, oxides, and polymers, and the polymer direction has even been abandoned."

"Because polymer electrolytes have very low conductivity at room temperature, they need to be developed and applied in a high-temperature environment, and their commercialization prospects are the most uncertain."

"Sulfide electrolytes have poor air stability, and will produce toxic gas hydrogen sulfide when exposed to the air. It will also destroy the electrolyte structure and weaken the electrochemical performance."

"So this route relies heavily on inert gases and drying chambers for synthesis, storage, transportation and application, which is high cost and low safety."

"Oxide electrolyte is the route we take. This kind of route requires high-temperature sintering, which will lead to serious interface chemical reactions."

"Except for the materials from our institute, other known materials still produce lithium dendrites, which does not fundamentally solve the problem."

Chang Le said: "Academician Liu, from what you said, we are leading the world?"

Liu Chaodong said: "Boss, I conservatively estimate that we are about 10 years ahead."

"Moreover, from the perspective of the technology itself, our solid-state batteries are very safe and stable. Once the cost is reduced, we have great prospects for promotion."

Chang Le nodded.

In his opinion, Liu Chaoyang's judgment was generally consistent with the situation he recognized in his previous life.

In the past life, in the next 10 years, many countries and institutions did invest funds into the field of solid-state battery research and development.

The number of papers published in relevant top journals has increased exponentially.

Various propaganda reports emerge one after another.

It just didn't leave the lab or be loaded into the car.

Many institutions or brand manufacturers’ so-called announcements of successful research and development are mostly market hype.

In the previous life, F Tian said it would launch solid-state batteries as early as 2011, but as of 2023, it had not yet seen the product.

This shows that on the one hand, product development is difficult, and on the other hand, F Tian is bragging.
