In the live broadcast room, according to the process, Feng Hao started the first live broadcast process today to popularize relevant information about sodium-ion batteries.
"No more nonsense. Our first task today is to introduce sodium-ion battery technology that many people are not familiar with."
"Speaking of batteries, in daily life, everyone should have heard of various battery technologies and have access to various batteries."
"First of all, the most common is the dry battery, a chemical battery that uses a paste electrolyte to generate direct current. The dry battery is a disposable battery that is commonly used in daily life. It is commonly found in radios, walkmans, remote controls, flashlights, toys, etc. On top of small appliances.”
As he spoke, Feng Hao took out a few batteries from his pocket and displayed them on the live broadcast room screen.
"The common dry batteries are zinc-manganese batteries, which are the most common and easiest to access batteries."
"But this kind of battery has many shortcomings. It cannot be recharged, the battery capacity is small, etc."
Throwing the dry battery in his hand aside, Feng Hao turned around and picked up a heavy battery from the cart next to him.
"Then there is another common battery, the lead-acid battery, which can be charged and discharged. The battery capacity is larger, but it also has many disadvantages. It is huge in size, has poor battery cycle performance, and has strong attenuation in cold areas."
Feng Hao put the lead-acid battery in his hand back on the cart, and then picked up another battery.
"With the development of battery technology, various lithium batteries have begun to appear!"
“Unlike ordinary lead-acid batteries or dry batteries, lithium batteries have higher energy density.
The amount of electricity that can be stored in the same volume is much greater than that of lead-acid batteries, and the cycle performance is also better. It is a relatively complete battery technology.
Nowadays, in terms of lithium battery technology, Hengxin Battery Company can be said to be the first echelon, or a unique existence!
The lithium iron phosphate batteries produced by our factory, after continuous technological research and development, are far superior to other ternary lithium batteries, polymer physical batteries, etc. in terms of initial safety performance.
Up to now, our lithium iron phosphate batteries have far exceeded ordinary lithium batteries in terms of battery cycle times, energy density, high and low temperature performance, etc. "
"However, the performance of such a battery in all aspects can already meet the needs of automobiles and the use of battery replacement technology."
"But even the lithium iron phosphate batteries produced by Hengxin Battery Company still have some fatal shortcomings."
"The most important one is the scarcity of lithium ore resources, which makes lithium-based batteries unable to be manufactured and applied on a large scale, and the production cost is high, etc."
"Many people are now aware of the difficulties faced by Jiuzhou Automobile. The price of raw materials for lithium iron phosphate battery production has skyrocketed. Industrial-grade lithium carbonate has increased from 30,000 yuan per ton three years ago."
"In the past few years, Jiuzhou Auto's battery production has doubled and the price has increased to 60,000 yuan per ton."
"Now the price has reached an incredible height. In just one month, it has risen to 830,000 yuan per ton!"
"This is a price that is extremely inconsistent with the laws of the market. As for the forces with funds and strength that can cause all this, everyone should be able to guess it."
"But fortunately, Kyushu Motors has already anticipated this situation, and the solution is sodium-ion batteries."
"Industrial-grade lithium carbonate resources can only be produced into the lithium iron phosphate batteries we use today after processing, which is very rare."
"As for sodium-ion batteries, there are not many ores that exist in nature, but sodium is a very common element in our lives, and its extraction is relatively simple."
"The main components of ordinary edible salt are sodium chloride, soda ash contains sodium carbonate, baking soda contains sodium bicarbonate, MSG also contains sodium glutamate, etc. The raw materials for the production of sodium-ion batteries are much better than lithium ore. Resources are simpler and can be obtained more easily.”
"Battery technology based on sodium will no longer have the various problems of lithium-based lithium iron phosphate batteries."
"Of course, if all were benefits, scientists would not give up sodium at the beginning and use lithium as the raw material for batteries."
"Lithium has a lower atomic weight and smaller ionic radius, making its theoretical mass specific capacity 3.3 times that of sodium, and its theoretical volume specific capacity being 1.8 times that of sodium. Moreover, lithium's potential is higher, 12% higher than sodium, which makes it In terms of energy density, batteries made of lithium materials are also more advantageous.”
"Sodium-ion batteries have much higher stability requirements for positive and negative electrode materials than lithium-ion..."
At the center of the stage, Feng Hao popularized relevant information about sodium-ion batteries to the large audience.
In the live broadcast room, the audience listened with gusto, and there were even fewer barrages!
It wasn't until the end when everything was explained clearly that there was an enthusiastic response in the live broadcast room.
————————
"That's it, wonderful, sodium-ion battery!"
"I didn't understand it, but it seems very powerful!"
"Although I don't understand either!"
"In short, it is a lower-cost battery that is not limited by lithium ore resources."
"In terms of performance, will it be much lower than Hengxin Battery's previous lithium iron phosphate battery?"
————————
Looking at the projector screen, many viewers still didn't understand, and Feng Hao sighed helplessly.
But the good thing is that Kyushu Motors already has a specific product. Just talking about performance is OK. The audience actually doesn’t need to know where this battery comes from. Whether it works well or not is what they really care about!
Feng Hao clapped his hands and smiled toward the camera.
"So what is the performance of Kyushu Automobile's sodium-ion battery? I believe everyone must be very curious. Let me take you to understand this question one by one!"
"First of all, in terms of battery performance, let me introduce to you this second-generation sodium-ion battery from Hengxin Battery Company."
"Yes, you heard it right, the second generation sodium-ion battery!"
"In fact, as early as last year, Kyushu Motors had developed the first-generation sodium-ion battery technology."
"It's just that compared to lithium iron phosphate battery technology, the performance of the products produced by the first generation of sodium-ion batteries is much worse than today's lithium iron phosphate batteries."
"Although it is barely usable, it can only be used a little bit, so Kyushu Motors did not mass-produce the first-generation sodium-ion battery technology, but continued to develop the second-generation sodium-ion battery technology."
"With more than a year of continuous research and development efforts, we finally broke through the difficulties of second-generation sodium-ion battery technology a few days ago and successfully achieved mass production of second-generation sodium-ion batteries."
While Feng Hao was talking, a staff member had already rolled out a large battery pack on a cart.
"Behind me is an experimental sample that was just produced today. Let me take you to learn about this battery pack."
"I believe many consumers will recognize the shape of this battery pack."
"That's right, the battery packs that have been standardized by Dongfang Electric Power Company can be used in various new energy trams."
"The volume is the same as the previous lithium iron phosphate battery, but the mass is slightly heavier at 8.2 kilograms, and the amount of electricity it can store has not changed much, it is also 70 kilowatt hours."
"The performance in all aspects is basically the same as the previous lithium iron phosphate battery pack, but there are also some improvements, including stronger high and low temperature performance!"
"It can be used normally at temperatures as low as minus 30 degrees. Even in the winter in northern my country, it can maintain battery attenuation within five percent, which is even better than previous lithium iron phosphate batteries!"
"In terms of battery cycle performance, it is slightly less than the 7,000 cycles of lithium iron phosphate batteries, with only 6,000 battery cycle performance."
——————————
The performance data in various aspects and the comparison with previous lithium iron phosphate batteries made the audience in the live broadcast room more aware of the battery performance of this model.
"My Jiuzhou Automobile Company and Hengxin Battery Company are amazing!"
"I thought that this new battery would be much weaker than the previous batteries in all aspects, but I didn't expect that it would have basically the same performance as the previous lithium iron phosphate batteries!"
"Jiuzhou Motors is well prepared. Is it already the second generation of sodium-ion battery technology?!"
"In other words, I feel that this new battery is more powerful. With the continuous advancement of technology research and development, it will definitely be better in the future!"
"Although the number of cycles is reduced by a thousand times, the production cost should be reduced a lot, sodium can be found everywhere, and there will be no problem of stuck raw materials. Overall, it is much better!"
"You can also buy electric cars in the Northeast. Wow, it's good. I look forward to the construction of battery swap stations in the north. We must support our Jiuzhou Automobile!"
————————
The live broadcast continued while the audience was talking.
Feng Hao showed a bright smile: "After briefly introducing the performance, now comes the focus of today's introduction to sodium-ion batteries, battery safety performance display!"
"Jiuzhou Motors, from the previous low-speed electric vehicle era, we have been emphasizing one attribute, and that is safety, safety, safety!"
"Compared with ordinary fuel vehicles, battery technology has many advantages, but it also has some disadvantages. If the battery quality is not up to standard, it can easily cause a series of serious consequences."
"For example, thermal runaway of the battery may cause safety hazards. Traditional lithium batteries contain huge amounts of energy. If you are not careful, the thermal runaway of the battery may cause a fire," he said.
"And this kind of flame often quickly explodes, deflagrates, or even explodes within a few seconds or more, causing terrible consequences!"
"I wonder if you have noticed the burning incident of new energy electric vehicles caused by some inferior batteries."
When he said this, Feng Hao paused slightly.
The screen in the live broadcast room switched, and a car with a mosaic brand appeared on the scene.
In the video, a high-speed electric car collided with a truck.
Due to the violent collision, the new energy tram vehicle caught fire and burned for more than ten seconds. The raging fire ignited the entire vehicle.
After more than ten minutes, the flames gradually extinguished, and only the remains of a car were left at the scene.
————————
"Hey, hey, can electric cars ignite spontaneously? I didn't know about such a thing!"
"This seems to be a niche electric car brand abroad. It has developed very rapidly in the past two years, but the car seems to have quality problems. This has happened several times."
"It's so shocking. It burned very fully. It was burned directly into the frame of the car. If the car owner was a little slower, he would have been cremated easily without having time to escape from the car after the accident."
"Not to mention the power batteries used in electric vehicles, several lithium batteries that have been used before have caught fire and exploded!"
"Looking back and thinking about it now, several years have passed, and I have never heard of a Jiuzhou car burning violently due to battery problems, causing a vehicle fire!
Whether it is Kyushu Motors, Huaxia Motors, or earlier low-speed electric vehicles, including a large number of two-wheeled electric vehicles, no fire accident has been heard of in these vehicles using Hengxin batteries! "
